Coming Down To The Wire

Ordering for BBotE will be turned off this evening at 10pm PST.  For you people who like to wait until the last minute, I have one 1000ml FMJ and one 350ml FMJ Stein of Science on hand.  Grab them now if you want them, otherwise they go in my luggage to Australia & New Zealand.  You never know, a wallaby or kea might steal them from me.

Goddamn keas

Last Call: A Literary Review

Last Call for BBotE.  I’ll stop accepting new orders on June 17th, resuming July 13th.

In other news of a Last Call nature, I highly recommend the book by the same name written by Daniel Okrent.  While the over-arching story of Prohibition, the abolition/temperance/suffragette movement, and the 19th century religious revival is one I am familiar with, this book has been fantastic at filling in the names, dates, and fine detail in the story.  I think I’ve read roughly a third of the book out loud in dramatic style to the delight/annoyance of my girlfriend.

What strikes my most while reading it is how very little has changed in the tactics of the control of illicit substances, attempting to legislate morality, and general manipulation of the American political process since the dawn of the Anti-Saloon League.  We are still inheritors of the temperance movement’s textbook approval process where they gave up on the adults and instead tried to educate a generation that “would hate the bottle” to vote the previous generation away.  Sound familiar?  The marginal politics of micro-targeting and “single issue voters” in the last 20 years are nothing new; the original yes/no political litmus test was “Are you dry or wet?”.

It makes me want to cry into my beer and keep reading.  I am very thankful for my legal beer.

SCIENTIFIC DRINKING TOUR 2010 – Sydney, Australia & Christchurch, NZ(possibly)

To celebrate the upcoming nuptials of Test Subject Astrophysicist, Herr Direktor Funranium will be touring the Dominion of Oceania from June 24th-July13th.  If you are a denizen of Australia or New Zealand and wish a Stein of Science hand carried with significantly reduced shipping, now is the time to drop me a line.

The secret of the Black Blood of the Earth travels with me and batches may be conjured during my travels for lucky locals…yes, I am looking at you KAOS.

SCIENTIFIC DRINKING WORLD TOUR 2010 – Portland, OR

Now in our third day in the Rose City and the stats are pleasing.

Beers consumed: 6 delicious imperial pints and counting

Black Blood of the Earth Distrributed to Portlanders: 2.5L and counting

Hours slept: not enough, but that’s the cost of fun.

To the folks at the Lucky Devil, McMennamins Imbrie Hall, and Deschutes Brewery, thank you for humoring the man with the strange stein and filling it with beer, but only charging me as if it were a normal pint. I happily explained how the steins worked to a few employees and interested fellow patrons at each place. When I shared my belief that beer should be consumed at the temperature it comes off the tap, one of the bartenders nodded sagely and declared, “That’s why I work behind the bar, man.”

BBotE: Recent Developments (2/8/10)

Coffee Science is a forever advancing field. Like other disciplines, it comes in fits and starts, though this could be due to caffeine. Even more important is the role of happenstance in the advancement in the body of human knowledge; the headscratching declaration of “Huh, well, that wasn’t supposed to happen.”

This last Sunday, I went to decant a delicious taste of Kenya BBotE that I’d prepared earlier in the week from one of my many storage Erlenymeyers. To my great distress, the ground glass stopper refused to give, denying me the caffeine boost I so desperately needed after a night of sea chanteys aboard the S.S. Balclutha. Crisis! Brute force did not work, so I resorted to physics.

I ran the flask under the hot tap for a couple of minutes in the hopes that the expanding vapor in the head space would pop the stopper. No such luck. Frustrated, I then placed the flask in a boiling water bath and patiently waited. *Insert Adages Of Pots And Boiling Water Here*

Thirty minutes of boiling later, I finally free the stopper. I take a sniff of the BBotE just to see if boiling harmed it. Oh dear, it smells like the finest of burnt Army Grade sargeant coffee. A taste confirms the smell: revolting.

BUT, this is a valuable learning moment. My previous hypothesis that my cold extraction technique preferentially extracts somethings and not others may still be valid. This little misadventure instructs that the horrible burnt coffee flavor is the result of prolonged overheating of the coffee, regardless of methodology to generate it. Whatever decomposes in heat to create this flavor is present in perc coffee, espresso, and the Black Blood of the Earth. It reinforces my directions on serving preparation: add BBotE to hot water, don’t boil BBotE on the stove, and if you’re gonna have it straight but want it warm, don’t over microwave it.

RECENT DEVELOPMENTS (3/7/10): BBotE vs. Analytical Chemistry FIGHT!!!

So, last week I finally got some quantitative analytical work done on the BBotE courtesy of some chemists who demanded to know exactly how much caffeine they were consuming and why it was so tasty. Thus far, I’ve only had the qualitative results of “Yup, sure seems to make people awake in small quantities.” We’re getting down to brass tacks here and asking how much for the monkey.

First, let’s revisit a toxicology concept known a Lethal Dose, or LD. It is normally quoted like this: LD 50/60. This translates as the acute dose that will kill 50% of the exposed unfortunates (see also: the title of my friends page) within 60 days. This *does not* mean that 50% is all that dose will kill, but it is important to put a milestone for measurement and at some point it is hard to tell if it is the acute dose that killed or something else. Also, this only works for acute dose; chronic exposure is a lot more difficult to quantify. In general, acute dose is organ failure, chronic dose is cancer.

For caffeine the LD50 is 192mg/kg of body weight in rat. It is somewhat concerning to me that the second suggestion from Google when I type in LD50 is “LD50 caffeine”. A normal 7fl.oz. cup of coffee contains between 110-170mg of caffeine depending on the varietal and how much robusta bean they snuck in on you. The standard toxicological model 70kg man would need to drink in the neighborhood of 90 cups of coffee to achieve LD50. Keep in mind that some people are “weak rats” and their lethal dose threshold is considerably lower. Still, that’s a lot of coffee. Just think of all the urination involved with that much fluid!

Okay, now that’s out of the way. For the experimental set up, I made preparations of 24, 48, 72, and 96hr steeped Kona all from the same batch of beans to check time variation in caffeine quantity. From the remaining beans, I also made a small pot of perc coffee and espresso to then test the BBotE against different preparation methodologies. Sadly, the espresso sample did not make it to the lab for analysis. 5ml of each sample was then placed in a small vial and allowed to evaporate in a fume hood. Once this was done, the dried residue was brought back up in a solution of methylene chloride preparation for sample loading into the gas chromatography (GC) unit.

Observations during sample prep:

1. Before serving, I generally recommend people shake the bottle before pouring. The 24hr sample was the most “frothy” with decreasing frothiness with time. This went counter to expectation as I guessed that longer exposure would draw more oils out causing this effect.
2. The light transmissivity was directly proportional to time in solution. The longer the sample had been let steep, the more opaque it was.
3. The evaporation rate was directly proportional to time in solution. The longer the sample had been let steep, the longer it took to evaporate. Strangely, the perc coffee sample took the longest to evaporate.
4. None of the BBotE samples moldered while exposed to open air, though the perc coffee did so within two days.

The samples were presented to the GC lab manager, along with a complimentary bottle of BBotE in thanks for letting us abuse her machine. After a brief training run using ethanol blanks, we ran ran the 24hr sample and saw a really nice sharp caffeine peak comes up on the trace. At this point, I left the lab and handed control of the machine over to the Funranium Labs Staff Chemist. He ran the 48hr, and saw slightly a lower peak…hmm. So then he ran the perc and also saw a lower peak than the 24hr. With some head scratching, he ran the 96hr.

Have you ever played with an oscilloscope and turned the gain up too high such that you lost the top of the peak and looked squared off at the top? Well that’s what we had. It was around this time that the GC lab manager came back in, declared HOLY CRAP!!! and ended the run. She then looked with concern at the trace, then the bottle of BBotE I had given her, and then asked my chemist, “How much of this do I drink to *not* die, because this is awesome.”

And thus she was welcomed to the Esoteric Order of Funranium Labs Test Subjects.

I learned this all by my chemist reporting to my office with a hangdog look on his face. “I’ve got some bad news and some good news, Phil.”

Phil: “Okay, what the bad news?”
Chemist: “There was so much caffeine it over-saturated the detector and probably blew the calibration.”
P: “Crap. What’s the good news?”
C (jumping up and down with glee): “There was so much caffeine it over-saturated the detector and probably blew the calibration!”

We’ll be trying again next week with a 10000:1 dilution in hopes that we’ll get a number that we can use, rather than a borked machine. I am finding it likely that I will need to make an LD50 statement on future bottles of BBotE rather than the imprecise “High Caffeine Content”.
