BBotE Now Has A Pretty Label

Behold the 1L, 750ml, and 375ml bottles in all their labeled glory!  Many thanks to the artist, Erin Hall, who created the erupting Mt. Caffeination and did the much more arduous template design to make things fit on the different bottle sizes.  It is important for a man to be able to admit the things he does not do well and get a professional to help; art is one of those things.

The first express mail test shipment of 1L of Kenya BBotE to England went in the mail this morning.  Shipping cost as much as the precious contents within, with the amusing total of $51.50, so we’ll see how it all goes.

BBotE Update: The Lost Ethiopian Post & Guatemala

For the week of April 1st, I chose to revisit an old favorite that had met with good reviews, Ethiopian Yirgacheffe. Previous iterations of Yirgacheffe BBotE had been described as pleasantly earthy with peanut overtones, but this time came out different. In fact, there was a strong gender based difference in opinion on the flavor when presented to my Usual Subjects.

This particular batch was received within 12 hours of leaving the roaster before being put up into solution. While extracting, it proved one of the more oily creations I’ve had, challenging the Colombian Finca Yara . The surface tension of this BBotE was such that, when shaken, drops would bead on the surface before sinking and merging into the blackness.

When given to men, as a straight cold shot, there was uniform agreement that it was “fatty, greasy…but I like it” on the immediate taste. None of us agreed on the aftertaste. One declared it to be “rich, rich, melty fudge” and other said it was “smoked ribs”. To me, it was like heavily buttered movie theater popcorn. My hypothesis is that there was a good hard stomp on the fatty taste bud and then the rest of the tongue was extremely confused trying to figure out what just happened. This is largely dependent upon the “flavor library” you have trained your tongue and brain with over your life. So many smells and flavors are completely tied up in memories that describing whatever you just drank turns into a small biographical journey to bore your fellow drinkers with, who really wish you’d just shut up and enjoy it already.

The women, save one, uniformly declared the Ethiopian to taste like “burnt caramel”. The exception has a long established her aversion to dark roasts of any shape or form and finds them to be “burnt dirt”, though she did declare that she could see where others might have found caramel. Go figure.

The traditional alcohol test of adding one part straight vodka to three parts BBotE yielded a pleasant cocktail, but very little change in BBotE flavor. The fatty mouth feel was muted, but otherwise unchanged.

To be honest, I am not nearly well read enough in neuroscience to say anything definitive but I find this all tremendously interesting.

A week passed…

For the April 8th experiment, I tried another freshly roasted batch but this time a nice Guatemalan medium roast. The flavor yield was good but the mouth feel was something new and different from the previous week’s Ethiopian. During extraction, it seemed to be far less oily or frothy than the Ethiopian but on initial taste had a strong fatty hit on the tongue. This was immediately followed by an almost martini-like sensation of dryness on the top of the tongue. Aftertaste and mid-palate flavors were uniformly declared to be “nutty…like hazelnut or Brazil nut”. One person found a hint of chocolate that made her ask if I’d added Nutella to her sample.

The traditional alcohol test of adding one part straight vodka to three parts BBotE caused the Kenya-like explosion of sweetness. Indivdually, neither BBotE nor straight vodka are sweet; combined in those proportions, it became dangerously drinkable as a liqueur with no additional sugar.

And now for some well earned beer.

Coffee/Booze Update 4/10/10

I was going to try to recreate the post I made on 4/7/10 before communist fifth columnists who hate freedom destroyed it, but under the conditions of exceptional insobriety courtesy of the nice people at the St. George Distillery that’s not going to happen. They have just held a release party for the Firelit coffee liqueur to which I was invited and do not hesitate to recommend. Imagine, if you will, Kahlua that…well…doesn’t suck.

Kahlua has always been a problematic mixer in my bar as it tended to lend more of a chocolate character to cocktails than coffee. It is syrupy and tends to stick to the palate. As a man with Brimley Disease (AKA Type II Diabetes), this is a sure fire signal that I probably shouldn’t be drinking it or anything using it.

Enter Firelit. Using Bluebottle coffee and a brandy base, the Firelit liqueur manages to capture the essence of the coffee in a manner similar to the Black Blood of the Earth without turning it into treacle. It is has all the flavor but the lightness of brandy that makes it a pleasure to consume on it’s own. I cannot even begin to conceive of taking shots of Kahlua without serious cash money and honor being on the line.

The fact that the K value of caffeine in ethanol is not far off from water means that there is a bit of caffeine kick to it. One BBotE test subject who picked up a bottle of Firelit, excited about having “coffee but able to sleep afterward” was sorely disappointed when she found herself still awake at 4am after having a glass at 9pm.

I am to understand that it is currently sold only in California but that it can be ordered in most of our fair union. K&L is my shipper of choice.

And now, bed. Maybe. I’ll be lying down at the very least.

BBotE Recent Developments (3/26/10) – Shipping Is A Possibility, New Test Subjects, A Chemical Review and Sulawesi

Following a three week countertop exposure of Kona BBotE at room temperature in sealed bottles, the verdict is in: Black Blood of the Earth can survive shipping without prohibitive cold packaging. I did testing with both air in the headspace of the bottle and with carbon dioxide. A future test with nitrogen may need to be done.

The first noticed change in flavor of the air headspace happened in the first 24hrs, which I attribute to the difference in mouth feel between cold and hot beverage. The warm BBotE was similar in flavor to what I am accustomed to when adding one part BBotE to three parts hot water from magical Japanese hot water machine in the breakroom at work. Flavor was consistent thereafter from 2-10 days. At 12 days, I noticed a slight tannic note sneaking in. By 18 days, the flavor had become distinctly “tangy” even when added to hot water. This stayed consistent thereafter.

The carbon dioxide head space had a similar flavor progression, but off the bat had a minor carbonic bite from the dissolved CO2 in solution. The “tangy” character was less at the 18 day mark, but still there.

Interesting to note: at no time did either trial bottle develop mold. This is a corroboration of the observation while evaporating samples for caffeine content analysis that, even while standing open to fume hood air for three weeks, none of the BBotE samples moldered.

In other interesting news, it is possible that I have identified the chemicals responsible for creating “butt cofffee” flavor. You know, the horrible taste from burnt, long ignored coffee. The likely culprits that are known to be present in coffee beans are thiols (well known in chemistry labs for their fishy aroma) and putrescine. Yes, putrescine as in “the smell of corpses”. Really, putrescence is a decay product from the breakdown of proteins, which is something that happens to all living things, including coffee beans and people (special thanks to the Funranium Labs Staff Mortician for explaining this). Of course, heat will accelerate this process which is why being a coroner on the east coast during the summer sucks so very, very much. The same goes for overheated and then ignored coffee. Just beacuse you stopped heating and walked away doesn’t mean the protein breakdown stopped.

At the request of one astute reader, I performed a 48hr BBotE preparation of Sulawesi beans. Sulawesi is well known for making a very pleasant smelling, rich, and low acid hot coffee. Sadly, these characteristics made a somewhat weak BBotE. Perhaps it needed more time to draw more out of the beans, but the defining description from the test panel was “bland but drinkable”. I may try some longer term preparation another day in the interest of science. The aroma of the beans themselves is so delightful that I know something wonderful is hiding in them.

I would like to also welcome Test Subject Puppeteer to the ranks of the BBotE cohort. After approximately 1.5oz each of Kona and Kenya BBotE, in straight and vodka mixed formats, he declared “I feel alert…actually, I feel really competent”. It was as if he had consumed the elixir from Egg Shen’s gourd. He felt kind of invincible. This may explain the later attempts make his mummy puppet dance on the bar while standing on a folding chair. Following a near mishap, he decided it more prudent to instead stand on the table and dance with his puppet. At 2am, he rode his bike from West Hollywood to his home in Koreatown and went to sleep, at his own chosing, not because he was tired. His remaining BBotE supply is now being rationed for a future night of exceptional productivity.

Test Subject Censorian gives this self-assessment:
“4:00am: drank ~1 oz of batch 031510-1-3. Effects were subtle but noticeable. (I was staying up all night in order to get to work on time.) In 22 minutes I went from groggy zombie hell to efficient focused web surf(land). I had five tabs open, all dedicated to different aspects of the California Aqueduct and Los Angeles Aqueduct intersection. At 6:00am I was comparing two different topographical maps of the area around the St. Francis Dam. By 7:00 am, I felt the effects declining, and opted for a Diet Rock Star, rather than waste BBotE on such menial work. At 7:30am I left, feeling quiet but functional, for my first training day at the U.S. Census Bureau.”

In the meantime, keep watching here, the Etsy store, or the Funranium Labs facebook page for the official announcement that Black Blood of the Earth is available for shipping. It won’t be long now…

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.

Figure 3: Samples in methylene chloride, with color gradient presented

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”.
