Off-Topic and Back Again: “Framing”, Cluetrain Manifesto, and Twitter

“Framing” came up briefly on one of the other small independent blogs I follow. I’d link
to the post but it’s gone now. I sincerely hope its disappearance wasn’t related to the
comment I posted there, unless it was just because of the “don’t feed the trolls” part
of it – (in which case excuse me for a moment while I tell myself what an amazing fountain of useful advice I am and feel self-important for about 15 seconds before I return to reality…). I’m guessing the poster just decided he didn’t want to keep the post, but I won’t let that spoil my brief ego-feeding fantasy.

For those lucky enough to have missed it so far, here’s my flippant and extremely brief explanation
of my understanding of how the “framing” thing goes. An assistant professor of communications popped up among the science blogs one day with what seemed to begin as a couple of reminders of the obvious (mainly because it occasionally seems that people have forgotten). Namely, that if you want someone to understand what you are trying to communicate (particularly scientific matters) and agree with you, you are more likely to succeed if you can connect what you are discussing to something that your audience already cares about, and you are less likely to succeed if you are, shall we say, unfriendly to them as you present your subject.

From there, “framing” seems to have grown into something resembling the brand-name of some kind of mass-market “self-help” product line. Its primary proponent, from the distant vantage point
whence I occasionally catch a glimpse of the fight, starts to seem like the angry Vice President
of Communications for Science, Incorporated, whose office issues angry memos denouncing the insubordinate “screechy monkeys” who insist on deviating from the approved language when discussing Science, inc.’s Mission Statement. The fact that science is a conversation among people rather than a corporation probably explains why so much of the response has been not “Oh, crap, we’d better behave ourselves or we’ll get in trouble” but “Who the heck are you, and why are you telling me what I can say and how I can say it?” And that, I think, is all that needs to be said. (Anyone who stumbles upon my little blog and disagrees is welcome to say so in the comments.)

Book: The Cluetrain ManifestoActually, it’s probably more than needs to be said, and I wouldn’t have even mentioned it except that the problem of trying to apply this sort of approved “Command and Control” approach towards information in the Internet age reminded me of something else. The Cluetrain Manifesto was published so long ago that AOL was still considered a successful and valuable operation at the time, but it still seems to be relevant. (It’s free to read online – follow the link if you want to do so). At its core, its central thesis seems to be that the “Command and Control” approach to information management favored by corporate and political entities is effectively broken now because of the two-way communication made possible by a ubiquitous internet. In essence, “the market” is no longer made of isolated individuals passively sitting on the couch “consuming” the approved messages coming through the television, but a “conversation” of people who can easily tell the difference between a corporate “message” and authentic human conversation. Here’s a relevant passage:

“Imagine for a moment: millions of people sitting in their shuttered homes at night, bathed in that ghostly blue television aura. They’re passive, yeah, but more than that: they’re isolated from each other.

Now imagine another magic wire strung from house to house, hooking all these poor bastards up. They’re still watching the same old crap. Then, during the touching love scene, some joker lobs an off-color aside — and everybody hears it. Whoa! What was that? People are rolling on the floor laughing. And it begins to happen so often, it gets abbreviated: ROTFL. The audience is suddenly connected to itself.

What was once The Show, the hypnotic focus and tee-vee advertising carrier wave, becomes in the context of the Internet a sort of reverse new-media McGuffin — an excuse to get together rather than an excuse not to. Think of Joel and the ‘bots on Mystery Science Theater 3000. The point is not to watch the film, but to outdo each other making fun of it.”

Twitter logoAnd now we take one more step towards on-topicness: One current set of the metaphorical wires described in that passage is Twitter. Twitter is kind of like a gigantic lobby at a convention center where some huge conference is going on. The lobby is filled with little groups of people, collectively discussing with each other all kinds of little thoughts, observations, and events that each person there has encountered. You can easily wander through the lobby for hours, listening for snippets of conversation that relate to your own interests. Sure, being a raw, natural, human group of discussions, Sturgeon’s Law (“90% of Everything is Crap”) is in full effect. Sometimes literally: On Twitter I’m tracking the term “brewing” which seems to pick up more metaphorical uses of the word than literal, and a recent “Tweet” that popped up was somebody commenting that someone didn’t flush the toilet (“someone’s been brewing up a 1.6 gallon pot of turd stew.”)

So why bother? Because I think the remaining 10% has enough potential value to make a little mental effort to sift through the stream of messages worthwhile. I’d say a majority of the messages that come through are related to events happening at that moment. Twitter seems to get a lot of use as a back-channel for commenting on things that are happening, and for organizing impromptu gatherings. In most of these cases I think location information would be a valuable addition…and now I’m finally back to “on-topic”.

I think it’d be exceedingly nifty to be able to map Twitter messages in real-time. If I can convince anyone else that my “geostrings” idea is worth using, and then if one were to track “geostr”, any “tweet” with parseable location information would automatically show up. A small tag containing precise location information would make it possible for your computer automatically alert you if a post was describing something anywhere near where you are. Imagine the case of posts like “I just saw a tornado touch down, I’m going down to the basement now”. Or, say, “Who wants to try the homebrew I’m about to bottle?”

Example code in Javascript and PHP for picking out and parsing geostrings to follow soon. I’ll get back to yeast again shortly thereafter, though.

The care and feeding of Saccharomyces

Let me pause now for a moment to review what I’ve learned so far:

  • Yeast are filthy little jerks
  • No, seriously. I’ve previously reviewed their promiscuous sex lives,
    their sexually-transmitted diseases, and their toiletry habits. Somehow, though I still want to do more brewing, so let’s continue.

    Bag of 'Parodina Yeast Chow'.  I am not affiliated with Purina Mills corporation!  This image is PARODY!

  • Yeast need to be fed particular sugars
  • The three major elements needed by pretty much every living thing for “food” are Carbon, Nitrogen (as reduced “amino” nitrogen), and phosphorus (as oxidized phosphate) (Reduced sulfur is also needed in small amounts for proteins). Glucose (“dextrose” or “corn sugar”), fructose, or sucrose (“table sugar”, each molecule of which is made of a molecule of glucose attached to a molecule of fructose) are all used as carbon sources by Saccharomyces yeasts. Possibly also Galactose under certain conditions[1]. Saccharomyces yeasts don’t appear to be able to use lactose (“milk sugar”, each molecule of which is made of a molecule of glucose and a molecule of galactose), so some recipes include lactose in order to ensure there is some residual “sugar” in the mix at the end, for flavor and “body”.

  • Yeast need reduced nitrogen (amino nitrogen or ammonia…or urea)
  • Aside from sugars, this seems to be possibly the most important yeast nutrient. The most
    “natural” source of this nutrient would seem to be amino acids or very short peptides (2-5 amino acids long). Apparently urea (carbamide) also makes a good yeast nutrient, but:

  • You don’t want TOO much nitrogen available to the yeast, or there’ll be excess urea dumped back into the brew
  • This could combine with the ethanol to make “ethyl carbamate”, which is considered
    a probable carcinogen, at least if it’s present at a high enough level. Obviously if you use urea as a
    yeast nutrient, that’s only going to increase the possibility of a problem.

  • Saccharomyces yeasts are effectively incapable of using proteins for nutrition.
  • Proteins can be a source of amino nitrogen (and carbon and sulfur), but like all real microbes, yeast cells cannot just “eat” chunks of protein. They have to be broken down into very small chains of amino acids or even as individual amino acid molecules before the yeast can suck them up and use them. Saccharomyces yeasts do not appear to normally excrete protein-digesting enzymes, so by themselves they cannot make any use of protein for nutrition[3].

  • Yeast need oxygen
  • Oxygen is necessary for making certain components of the cell membrane, in addition to it’s more obvious role in respiration. Without a way to replace used up membrane components, the yeast stop reproducing and eventually fall apart and die. There seems to be some suggestion that to a certain extent one can substitute some raw membrane material for oxygen here (either as “yeast hulls” or possibly even certain of the natural waxes on some fruits).

  • If you give yeast oxygen, though, they consume the sugars entirely instead of making alcohol…
  • …or do they? Between the “Crabtree effect” (when there are high concentrations of glucose, alcohol production continues even in the presence of oxygen) and indications in scientific papers[2], it seems SMALL amounts of oxygen may not be a problem, and might very well be beneficial.

  • Yeast need vitamins and minerals
  • B1 (“Thiamine”) is commonly mentioned, though apparently the need for it varies from strain to strain. Also potentially important are Pantothenic Acid (B5), Niacin (Nicotinic Acid, Vitamin B3), Biotin, Inositol, as well as Potassium, Magnesium, and trace amounts of calcium and a few other minerals[4].

  • Unhealthy yeasts are more prone to make (EEK!) Off-Flavors and Off-Odors (EEK again!)
  • For one thing, it seems to be a general rule that you don’t want your brew sitting on the corpses of dead yeast (the “lees” of wine, or “trub” of beer), because that is a potential source of (insert dramatic music and crash of thunder here)Off-Flavors and Off-Odors. Yeast dying and falling apart is also a major source of urea being dumped into the brew, too. Some strains of yeast under certain conditions, such as insufficient pantothenic acid, may be prone to producing nasty-smelling sulfides as well.

So, in most cases what we want to do when brewing is keep our yeast as alive and happy as possible, and get them to hurry up and finish our primary fermentation before they start dying off. Coming up: My (as yet untested) plot for accomplishing this – without specialized scientific equipment or materials.

What really counts as a “microbe”?

Just a brief pre-post before the main one I’ve got brewing now (which will be posted either later today or tomorrow).

A tapeworm: Since when does 30-36 feet long count as 'micro'???Microbiology is the dominating topic of this particular blog, but I don’t think I’ve ever addressed what I consider to really count as “micro”biology. This isn’t necessarily an obvious topic. My old “Microbiology” book from 8 years ago, plus the textbook from last year’s “Pathogenic Microbiology” class both contained large sections discussing organisms that are visible without a microscope. Heck, the “Pathogenic Microbiology” text even had a whole section on spider and insect bites. And, tapeworms? Since when is “over 30 feet long” considered “micro”? As I like to say: It’s time for Microbiology to grow up and move out of Medicine’s basement.

So: Here are the defining features of what I consider to be a “microbe”, at least for purposes of what I tend to discuss here on the blog:

  • Obvious: the organism cannot be effectively examined visually without a microscope and individual organisms can virtually never be observed by the “naked eye”.
  • In nature, a full normal population of a microbe can and will develop from a single live cell, and isolated individual cells are reasonably commonly observed.
  • Microbes do not “eat”.

It’s that last point that prompted me to write this post, mainly because it’s such an important part of why microbes work and how they affect their surroundings, especially when it comes to food microbes. What I mean by “do not eat” is that they are incapable of taking large (microbially speaking) chunks of material into themselves to use. Any cell nutrient for a microbe must be in the form of small molecules, like sugars, small peptides or individual amino acids, and so on that can be easily transported across the cell membranes and through the cell wall where applicable.

The importance of this is that for a microbe to grow on a complicated substance like meat or bread (for example), they have to excrete specialized enzymes that break down the substances out in the environment into simpler components like sugars or small peptides. If a microbe cannot secrete a protein-digesting “protease” enzyme, it can be surrounded by tasty, nutritious proteins and still starve to death. If a microbe can’t secrete an amylase (starch-digesting) enzyme, it doesn’t matter that starch is made of nice yummy glucose molecules because they’re all wadded up into long chains of starch that the microbe can’t get at.

And that, finally, is important because it brings up issues of growing multiple microbes together to accomplish something. Sake, for example, is made by fermenting rice, but rice is made primarily of starch. Saccharomyces yeasts don’t make amylases, so in order to make sake, you also have to add a kind of mold (Aspergillus oryzae, one of the types of white-mold-with-little-black-specks that you may see growing on the bread you’ve left sitting around for too long). A. oryzae is also a microbe and therefore can’t “eat”, but it does produce amylase. Since the amylase is breaking down the starches outside of the cells, this means the released glucose is also available for the yeast to use.

Admittedly, my definition above isn’t perfect. On the one hand, it leaves out protozoa (like amoebae and the well-known Paramecium, both of which actually do take in “chunks” of food, but both of which most people would normally consider to be “microbes”. It also leaves IN things like mushrooms, which are not usually thought of as being “microbes” by people who aren’t microbiologists. And, of course, it leaves me with no excuse not to go and learn something about eukaryotic (“plant”) algae (as opposed to bacteria-algae, a.k.a. cyanobacteria) and diatoms. Suggestions for updating my definition may be left in the comments…

Just something that came up while I was assembling what will be the next post. Stay tuned.

New toy: “Twitter”

Wow – Celestron takes 8 business days to get me a terse one-sentence answer. BigC responds in one. Impressive. Apparently their technical people are all at trade-shows at the moment so my bigger question will have to wait until they get back, but they were at least able to answer my question about their “tabletop” digital microscopes magnification (answer: the “600x” really is optical magnification, not digital.)

Another digital microscopy WANT/DO NOT WANT post to follow when I get the followup reply. Meanwhile, after hearing about it on the This Week in Tech podcast for a while, I finally talked myself into signing up to play with the coincidentally named Twitter system.

Twitter logoIt sounds like a really stupid idea – “Oh, goodie, now I can broadcast ‘text messages’ no more than 140 characters long about trivial events in my life to the whole world! Whoopee!” “Wow! I can find out when random strangers are drinking coffee AS IT HAPPENS!” Thrills! Excitement! Adventure!…

On the other hand, having the messaging system watch for particular words might be a handy way of monitoring current events. Plus, there seems to be a lot of potential for fun, off-the-wall uses, even if many of them are kind of silly.

It DOES seem like kind of an ideal context to play with that “geostrings” concept I’ve been toying with. A terse, easily-machine-parsed format for geotag data that can fit into a “twitter” post and still leave room for a sentence or two to go with the geographic information seems like it might be useful. If you’re so incredibly bored that you want to see some examples, you can check out my own Twitter posts, several of which I’ve embedded geostrings into.

Do Not Want: Celestron LDM

Back in Idaho for the moment. The trip was somewhat exhausting, but I thought a followup to The previous post on the Celestron LDM microscope was in order, as I finally got a reply back after almost two weeks.

(20080329:Quick update. I am surprised to see this post is getting more interest that I’d anticipated. I’ve added a brief summary to the end of the post to help clarify my opinion since it seems people may be interested.)

I had asked them if it was possible to replace the objective lenses (so as to be able to use an oil-immersion lens to get 1000X magnification – pretty much a neccessity for decent bacteriological work – such as examining yogurt cultures) and whether the camera could be swapped for a regular eyepiece. Larger yeast cells used in brewing might be okay in 400X, but even there it’d be nice to be able to zoom in adequately to get better detail – like watching conjugation or budding of yeast cells.

The answer:

“The answer is ‘no’ to both because of the sizes, etc. are specific to this unit.”

I guess there’s no point in asking about getting a darkfield condenser for it. On the plus side, they did actually give me a reply at least.

I’ve got to say I’m seriously disappointed that Celestron has evidently intentionally engineered this microscope product (and their other offerings as well, perhaps?) to Not Play Well With Others. Why else go to the trouble and additional expense of coming up with your own special specifications for the parts when standard parts are readily available?

This seems especially absurd in a product aimed at science enthusiasts, who strike me as very likely to be strongly aligned with the “Maker” attitude…at least if they’re any good at Science Enthusiasm. I think the “if you can’t open it, you don’t own it” concept meshes very well with the investigative attitude necessary for science. So, we want “internet”, and they give us “AOL” instead. A sad, sad fate for an otherwise great concept, and on this basis I must render a verdict of “Do Not Want”.

Find me a version of this product – from any vendor – which can accept standard oculars and objective lenses and I’ll sell blood plasma and beg on the street to raise money for it. (If nothing else, it’d give me an excuse to finally start up the “science begging” blog-post series I’ve been threatening for a while now…) Of course, it’d be nice to have an ordinary “real” microscope, too…this blog still doesn’t have enough pictures.
(P.S. Dear Celestron: although I doubt anybody at Celestron will ever even see my obscure blog, and in that respect my previous post’s comment about sending me one to review was just a joke. Despite this, I was sincere, so in the unlikely event that someone out there sees this post and has the authority and inclination to do so, feel free to send me one to review anyway. And a pony.)

SUMMARY (in my opinion):
Good:

  • VERY nice, highly desirable concept overall.
  • Self-contained, platform-neutral design, should work with anything that can support SD cards or USB Storage devices.
  • Potentially a nice field microscope? (Probably not hard to hack together a battery pack that could be used in place of the AC adapter)

Bad:

  • Does NOT appear suitable for bacteriological or similarly high-magnification applications
  • Non-standard components prevent upgrades.
  • Non-standard components mean vendor lock-in problems (if Celestron gets tired of making replacement parts and some kid scratches your objective lenses or cracks the viewscreen, you’re out of luck.)
  • Digital camera and viewscreen appear to be integral, so if the camera or viewscreen dies I’d guess the whole device becomes a useless lump.

My recommendations for Celestron or other microscope manufacturers (should any of them care about the opinion of some nerd on some obscure blog like this one):

  • Please, please use standard parts wherever possible – it makes your device a much safer bet for anyone thinking ahead towards possible upgrades or replacement parts.
  • Don’t ignore bacteriological applications.
  • Easily replaceable parts make for graceful failures. For example, if the camera on this model could be swapped for an ordinary ocular, the microscope would at least be usable while the camera portion was being sent in for repair or replacement.

More on the shocking life of yeasts

(Brief Update: Hello Ontario! Did I attract the attention of a Toronto homebrewing club or something? Anyway – welcome!)

I am amazed at how much depravity I uncover as I explore the mystery that is
Saccharomyces cerevisiae.

I’ve previously discussed how the filthy little beasts have drunken orgies and exchange sexually transmitted diseases with each other. Now I find out the inebriated little jerks are peeing in my beer, possibly to try to give me cancer!

No, seriously. Given enough “Free Amino Nitrogen”, for example in the form of the pirate’s favorite amino acid, like tiny little single-celled bladders, the yeast will start excreting extra nitrogen in the form of Urea all over whatever they’re growing in.

Of course, the whole time they’ve also been excreting ethanol. It turns out, under certain conditions urea (more formally known as “carbamide” nowadays) and ethanol will combine like drunken evil “Wonder Twins” to form Ethyl Carbamate.

Front Cover of the bookI ran into this as I was reading through my shiny new Wine Microbiology book, which has two pages on this yeast pee byproduct. An article linked to from fark.com recently reminded me of it and prompted this post.

To be honest, this seems a lot like the acrylamide media circus (compare the two links…) that popped up back in 2002. In both of these cases, we’re talking about a substance that occurs as a natural result of the preparation process rather than some new industrial chemical, and in both cases the processes in question have been around probably since prehistory. And in both cases, the real situation seems to boil down to something like “pay attention to your preparation technique, and if you try to live entirely on a diet of overcooked French fries and dessert wines, you might be at an increased risk for cancer.” QED. Or perhaps DUH.

Other than not trying to live on a French McDonald’s® diet, there are some things you can do when you brew to limit ethyl carbamate formation. Put very simply: don’t overfertilize your grapes because that can directly lead to unnecessarily high levels of nitrogen available in your wine, and don’t leave your bottles of brew in hot conditions for long, because ethyl carbamate forms faster in hot conditions.

There, problem solved. A more detailed “ethyl carbamate preventative action manual” may be found here. Meanwhile, I’m pretty sure our favorite drunken little micro-hedonists are too busy partying and making our wines and beers to be plotting our cancerous dooms.

WANT(?)

Picture of Celestron's LCD Digital Microscope My parents, apparently comfortable with being microbiology “enablers“, ran into a digital microscope (pictured at right) that they pointed me to. It looks pretty nifty for the price, except for one issue: it only comes with three objectives, topping out at 40X. I can find marketing materials for this microscope, but no technical information beyond what’s on the company’s website (click image to reach that). Therefore, I can’t tell if the objectives are replaceable or not. If they are, the idea of picking up an inexpensive surplus 100X oil-immersion lens and ending up with a decent microscope with which to watch the Yeast Porn and such – on a nice digital screen, no less, rather than squinting into an eyepiece – has a certain appeal to it. The fact that the digital camera takes the pictures itself and only needs a computer connection to transfer files – and not even then if you use an SD card – means that I wouldn’t have to worry about ending up with something that requires Microsoft® Windows® just to look at some microbes (or post glamour shots of them to this blog).

However, I don’t think trying to view conjugating yeast cells or, say, Lactobacillus or Gluconobacter/Acetobacter bacterial cells at 400X would be very rewarding, so an oil-immersion lens is a necessity. And don’t let the “up to 1600 Power with Digital Zoom” thing fool you – it just makes the picture bigger and blockier, not actually more detailed.

So….do I WANT, or not? I sent off an email to Celestron asking about whether I could swap out objective lenses on this model or not. I got back the form “we got your email” email – we’ll see if I get a real reply from them or not. If so, I’ll update this post.

Speaking of which – still no reply from Bristol Brewing Company. Guess they’re either just not “nerd-friendly”, or the person who handles email queries is on vacation or something.

P.S. Dear Celestron – if you were to send me an evaluation model, I’d be happy to review it here on my blog for the thousands hundreds dozens pairs of people who read my elegant prose incoherent babbling…

Where Was I?: “I’m going to have a place like this someday…”

Brewery building for the New Belgium Brewing Company in Fort Collins, CO

Quality Assurance lab at New Belgium Brewing Company, as seen through the 'employees only' door.Incidentally, did you know it’s a long way from southeastern Idaho to southeastern Texas? I made the drive last week, and I’ll be making the drive back as soon as I can get some things FINALLY done around here. On the upside, it’s kind of a fun, if long, drive other than Wyoming’s tendency towards having ridiculously high winds and roads paved with what appears to be a mixture of wet ice and motor oil. I made it down here though, but I’ve already been delayed about a week due to some issues getting inspection arranged on the home we’re trying to buy out here. But you didn’t come here to read me whining about that, did you?

On the way down, I did manage to stop at one of the two Colorado breweries mentioned in the “Wildbrews” book. New Belgium Brewing Company just happened to be only a couple of blocks away from my route through Fort Collins, so I took the opportunity to stop by and check them out.

If you’re familiar with them at all, it’s probably for their “Fat Tire” amber ale which I have seen in stores around the country, but I didn’t care about that. What I cared about is that they actually let their microbiologist (and, it turns out, their other employees too) play, and they have experimental “sour” beers in the same general style as Belgian lambics. Pictured at left is their famous one – “La Folie” (“the folly”). Well, the label on the tap for it, anyway. I’m not certain if cultures other than the standard canned strains of Saccharomyces cerevisiae are used in the initial ferment, but they then move the brew over to barrels that were previously used to age wine, and which no doubt contain a variety of traces of live lactic acid bacteria, other yeasts, and the like (their website also suggests they directly inoculate the beer with lactic acid bacteria as well). The brew sits in the barrel for up to 3 years. The result is nicely carbonated, and tastes almost sweet to me due to the pleasant tartness of the lactic acid. This particular brew is mentioned in the book. Seeing my obvious enthusiasm for the style, I was also allowed to taste a more recent concoction. “Eric’s Ale” was a lighter sour brew made with peaches which I absolutely loved. I really wish they’d had it in bottles for me to buy, but neither it nor “La Folie” were available in portable form, as far as I could tell. Guess I’ll just have to make my own. Once I finally manage to sit in one place long enough to try, dangit.

It was the Belgian Lambic-style ales that convinced me that I really do like beer after all, so long as it isn’t mass-market commercial swill (“Bladderwash”, as Leon Kania, author of “The Alaskan Bootlegger’s Bible” calls it) nor too strongly hops-flavored.

I did taste their “1554” ale – a “black ale” style that they were able to date back to at least 1554 while doing research on the style in Belgium, and several others whose names I don’t recall at the moment. One brew whose name I don’t remember was spiced with Yerba Mate – a caffeine-containing South American herb also found in Celestial Seasoning’s “Morning Thunder tea. (Ethanol is nice and all, but methylxanthines are my favorite…).

And, no, I didn’t forget their names because of drunkenness. When I say “taste” I mean I had a sip or two of each variety I sampled. They had these nifty little glasses like miniature brandy snifters for tasting. I’ll need to get me a set of those one of these days.

An unrelated bit of spiffiness about the brewery is that they seem to run the place as “green” as possible. They even go so far as to subject their brewing wastes to bacterial fermentation to produce methane, which they use to heat their water. How cool is that?

On a final, still unrelated note: there’s evidently been a fad of people selling things on eBay that have shiny surfaces, such as metal teapots. The trick is to take the picture of the item while naked, and standing such that one’s reflection is just visible in the picture of the item that appears on eBay. You know those classical shiny aluminum “Airstream” camping trailers? They had one out in the parking lot.

Photograph of New Belgium Brewing Company's 'Airstream' trailer.

Wait…I don’t see myself in that at all. Dagnabbit, standing in that freezing cold wind with everyone staring at me was a waste of time, wasn’t it…

The other “wild brew” place in Colorado is the Bristol Brewing Company in Colorado Springs. Unfortunately, the only indication I can find of their “wild” brews is a “sour beers” class they did as part of their recent “beer college” series, and a “Skull ‘n Bones” (evidently what they were calling their sour-beer series) T-shirt. As there is also no mention of brewery tours, I did send an email off to the person who appeared to be the contact for such questions, but I’ve yet to hear back. I’d love to stop by on the trip back, but the route will add a couple of hours to the overall trip. This would be well worth it if they’re doing tours, or still doing “sour” beers, or if I could even spend a few minutes chatting with their microbiologist. If not, though, I’ll just have to get on with working on it all myself.

Oh, yes, and the place in Austin that I previously mentioned was called “The Bitter End”…and it ended. Apparently a fire destroyed part of it, and now its being demolished to make way for a massive chain-hotel building. How sad.

Drugs make you stupid. And so does fear.

Ignorance breeds fear. Fear breeds terrorism. Terrorism breeds interruption of homebrewing. There was a disturbing article that came up today. Evidently, someone’s burglar alarm went off, so the security company drove by to check it out. They opened the garage (where I guess the alarm indicated an attempted break-in or something) and thought they saw a “still”. Naturally, anything that looks science-y with copper tubes or whatever can only be for one thing: drugs, right?

A bunch of police officers in both marked and unmarked cars AND the fire department later, somebody finally finds out it’s just somebody’s (completely legal!) homebrewing setup. Of course, officials describe the panic as “an appropriate response”. You might think this was in notoriously over-reacting Boston, but no – it was Hamilton, New Zealand.

My first thought was that it probably wasn’t even a “still”, which due to unrepealed prohibition-era laws is still treated pretty much the same that meth-lab equipment would be in terms of legality here in the US. I kind of assumed it was probably just the owner’s fermentation container, or possibly a wort-chiller (see image – click for context). Without some apparently-rather-expensive permits, it’s extremely illegal to have distillation equipment in the US, and I’m under the impression that most places around the world still criminalize home distillation. It’s worse, though – apparently New Zealand repealed the ban on home distillation for personal use over a decade ago. Even if what the panicky security guys saw really WAS a “still”, it’s STILL a completely legal piece of equipment there. And yet, surrounding the guy’s house with marked and unmarked police cars and firefighting equipment was “appropriate response.” Because somebody said “drugs”.

In fairness to the public officials, it sounds like once the police and fire department showed up, they actually talked to someone at the house (no tasing or teargas required) and had no trouble figuring out that nothing illegal was actually going on, so the damage was pretty much limited to the time wasted by the police and fire-department in responding. What I want to know is why the “security” company gets a free pass on causing all this fuss by reporting a completely legal piece of vaguely science-like equipment as a “clandestine drug lab”? At the very least, I’d expect people to want to know which “security” company is supposed to be protecting their houses but cannot tell the difference between legal homebrewing equipment and real criminal activity.

As a fairly hardcore nerd with an interest in intentional food microbiology (brewing, cheese, etc.) this kind of thing worries me. I intend to build myself a fairly decent science-lab setup for doing food microbiology. I’m already planning to label everything as though it were part of a public museum exhibit, just in case some idiot happens to see it and assume it’s some kind of terrorist drug lab or something.

Here in the US, I consider “amateur” science and technology to be part of the very foundation of my country’s greatness. Think Thomas Edison. Nikolai Tesla [yes, he was a naturalized American citizen]. Benjamin Franklin. And no doubt many, many others who are less famous but nonetheless made major contributions to the advancement of their country. When we set about attacking that, we’re harming our country – yes, you people outside the US, this applies to you, too.

The moral of the story is this: Please, people – science and technology are fun. Yes, there are many of us out here who quite happily set up “science-lab stuff” to play with food, or rocks, or plants, or electronic circuits or whatever else in a completely safe and legal manner. Sure, it’s a good thing when good police-work closes down some drug-crazed freak’s meth-production setup – I don’t want some idiot blowing up my neighborhood with unsafe chemical activity nor attracting violent criminals anywhere near where I live. All I’m asking is, will people please stop panicking and screaming “drugs!” or “terrorism!” every time you see some glass tubes or blinking lights? Please? Thank you.

I has a books.

I also has a bad grammar (curse you, internet!)

The front cover: 'Wine Microbiology - Practical Applications and Procedures'It’s slow going trying to get the mess up here in Idaho organized in preparation for the move to Texas, but I did manage to sacrifice a large number of my old books that I no longer need. Trading them in at the local representative of the “Hastings” bookstore chain got me a decent amount of store credit, and I was able to special-order this wine microbiology book I’ve been lusting after for months. It showed up a couple of days ago.

Very interesting so far, but I’m only a little ways into it. I’m still in the theory sections, so I can’t say if it covers yeast-mating or not (see previous two posts on this blog…)

Front cover: Wildbrews: Beer Beyond the Influence of Brewer's YeastPrior to that, I picked up a book I found at the local brewing-supply place in The Woodlands, Texas. It’s an entire book on the subject of Belgian and “Belgian-style” beers (like Lambic) fermented with “wild” yeasts and bacteria. It’s an excellent mix of history, science, travelogue, and “how-to”. I highly recommend it.

I noted with particularly nerdly glee that there are several breweries here in the U.S. doing non-traditional brewing cultures. At least one was brewing entirely with Brettanomyces yeasts! (Most traditional brewers and vintners shriek in horror at the thought of Brettanomyces in their brew instead of the standard Saccharomyces yeasts, blaming Brettanomyces for – you guessed it – “off-flavors“.)

That is so amazingly spiffy I can hardly stand it. I note that one of them appears to be only a few hours from the area we’re moving to. And two of them are in Colorado, more or less on the road between Idaho and Texas, so on my next trip down which is likely to be as early as next week, I may have to try to arrange to visit at least one of them and see if I can get a tour.
