BBotE Update: Longevity Test, MkII

Okay, as I sit here with a strange tea-like flavor in my mouth I think I can reliably report that BBotE is not meant to be stored for 6+ months.

All five samples that had made it this long were sampled this evening (Papua New Guinea, Sumatra, Ethiopian, Panama, and Yemen).  Why these five you might ask?  To be honest, they were the ones that were left after a party back in December 2009 where most of my 375ml samplers were completely consumed by the happy crowd or purloined before I could hide these ones.

I had previously sampled them at the three month mark and discovered that the flavor had not particularly shifted in any for the worse, although the Yemen was showing acidic hints.  The Panama, however, had aged remarkably well and gained an interesting cinnamon & caramel flavor as it aged.

At the six month mark, they were all undrinkable though with slight variations.  The Panama and Papua New Guinea had a strange acidic green apple flavor that came as a surprise.  The rest were tannic. Tongue to battery terminal, tannic.  They all are now probably eating their way through my pipes as a team since they went down drain.  I remain amazed by the fact that none of them had moldered in the slightest.

So, I stand by my declaration that you should store your BBotE cold and consume it within three months.  I am beginning a new longevity test considering that the previous samples were made with my old pre-January labor intensive and arthritis tempting hand-wringing and pressing process.  While the old hands on approach gave me a good appreciation of how things should look and feel, it also tended to let a lot of grounds through as filters failed.  Those stray grounds, in turn, would continue to leach acid into the BBotE.

More science…

BBotE Update: Malabar Experimentation

CURRENT INSOBRIETY STATUS: two 12oz beers and 85ml of Hangar One vodka.

Last weekend while reconvening the gaming group of old with beers and Steins of Science, I stopped by the Santa Cruz Coffee Roasting Company to see what interesting things they had on offer in the Fair Trade section.  As a hedonistic epicure, I do not require my delights to be procured in an ethical manner, especially if the tears of the downtrodden improve the flavor, but I am always drawn by the oddities the Fair Trade section tends to have.  This week, my discovery was the Malabar.

Where is Malabar you might ask?  To people that have heard me previously rant about the disingenuous use of “natural background” statistics without looking for local variations, you might be more familiar with the modern province of Kerala, in India.  Kerala has some truly beautiful, coconut strewn, purple sand beaches made of the sediment runoff from the Western Ghats…which have a naturally occurring radiation dose rate of roughly 14000mrem/yr (my annual occupational dose limit per the Nuclear Regulatory Commission is 5000mrem/yr).  This is because that beautiful purple sand is mostly monzanite, a thorium/uranium bearing mineral which may ring a bell to those of you that read the Origin of Funranium on the old site, oh so long ago.  By comparison, the natural background in the continental US, on average, at sea level is about 360mrem/yr.

I drunkenly digress. Where’d my glass go?

INSOBRIETY STATUS UPDATE: two 12oz beers and 125ml of Hangar One vodka.

When I opened the jar of freshly roasted Malabar, I was sold on the first sniff.  I am eternally on the hunt for good light roasts which should preserve as much of the fruity flavor of the coffee cherry as possible.  My scorecard currently is 1-1 with Panama (quite good, actually improves with age unlike all the other BBotE, worth repeating and sharing with the world) and Brazil (disappointing flat nutty flavor, maybe I got an old stale batch, not in a hurry to try again).  Several pounds went home with me to play with.

The resulting BBotE was quite complex and I am still wondering about it.  Similar to the Ethiopian, it exhibited high oil extraction with beading on the surface when poured.  Initial aroma struck me as having a hint of cucumber.  No one else agreed with this and questioned my olfactory sanity.  A general synesthesia agreement of a “green” smell was met.  Subsequent tasting I conducted with a different group 7 hours later did not strike me with the same cucumber smell, but the following day it happened again.  My nose may be broken.

On to flavor.

The initial flavor struck me as cool, not quite minty, and coating.  Then the mid and late palate came in and stayed.  To me, it tasted like a walk along the canals outside of Melbourne, FL smelled.  Florida is freakin’ alive compared to California and it is not possible to walk on an unpaved surface in that state without crushing some flowering low to the ground plant.  It was sweet, green, broken leaf & stem smell with the floral aroma of stomped flowers and it kept shifting.

The Vodka Test: as is usual, after my initial tasting I add what is roughly enough straight Hangar One vodka to make a roughly 3:1 BBotE to vodka mix to see what the alcohol can pull out.  Bizarrely enough, I got the taste of honey.  Again, my sanity was questioned and madness of the tongue proclaimed.

The experimental 2L batch of Malabar is now gone, but I think I will be playing with it again.  It’s a shame Santa Cruz Roasting Company is an hour away.

FYI: Impending Vacation Store Closure

Because of the preparation lag time, I will be turning off the ordering for BBotE on June 17th.  Because of the longer lead time for the steins, I’ll be turning off ordering for those on the 10th.  I will turn it all back on come July 12th when I return.

So, if you want something before I head Down Under now’s the time to hammer me with requests.

My Dental Hygienist Was Impressed

On my most recent trip for a dental cleaning, I was complimented by my hygienist for the lack of stains on my teeth for a change.  I told her it was because I’d more or less stopped drinking Coke since diagnosis with Type II diabetes.  She was impressed as the caffeine habit was pretty hard to kick.

Phil: “Oh, I still get my caffeine fix.  I drink coffee now.”

Hygienist: “Coffee?  You don’t have any stains though.”

P: “Oh, well, it’s stuff I make for myself specifically to cut the acidity and bitterness so I don’t have to add sugar.  Also don’t have to drink much of it either to get my fix.”

H: “Well, without the acid it won’t etch itself into your teeth.  That’s why you don’t have any stains.”

Hot damn.  Yet another benefit to add to the list.

Alas, Price Increases

Because my preferred dewar manufacturer has jumped up the prices of that most integral component of a Stein of Sceince, that translates to an increase in prices to you, the Scientific Drinking Public.  Not dramatic jumps, but noticeable.

My apologies, but such is life in the big city.

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.

Black Blood Of The Earth Now Available In CONUS

Alright, I have decided that sufficient testing has been done for survival of flavor in shipment.  I have put BBotE available up on the store in the 1000ml size only.  Though preliminary shipping tests show that the 750ml and 375ml sizes survive without bursting their lids, the locking bail top of the 1000ml bottle gives me comfort that nary a drop will be lost before reaching its destination.

Currently, I am restricting shipping to the continental US.  While I have proven that express mail can get BBotE through a rather stringent customs regime within 48hrs, the international shipping cost is almost as much as the BBotE itself.  Please drop me a line if you are beyond the borders of the 48 and in desperate need so we can figure out how to wrangle this for you.

Now, just to reiterate, while the caffeine content of BBotE is high, I do not know exactly how high.  I strongly recommend keeping consumption below 100ml/day.  By my rough calculation, you’ve got about the equivalent of a month’s worth of caffeination by Starbuck’s Ventis in that bottle.  While you could drink an entire case of Red Bull you picked up at Costco in a day, you probably shouldn’t.  The same wisdom applies to BBotE.  Know your limits and consume accordingly.

I am currently making it available in Sumatra (dark roast), Kona Blend, Kenya (medium roasts), and Panama (light roast) varieties.  Please specify which type you would like so that I know what to make.

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 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…

What Are Dewars?

A minimal jargon explanation, by Herr Direktor Funranium. Written while consuming a carbonated, no H2O Manhattan.  Standards of insobriety, with corresponding misspellings and grammatical errors, are being upheld.

The stupid simple, “Go away, yer botherin’ me, boy” explanation of how a dewar works is that it’s like a really, really good scientific-grade Thermos(TM). The average person will nod and walk away, no better informed than they were a moment before. That kind of behavior encouraging ignorance is inexcusable and is dragging down the march of progress.  We at Funranium Labs wish to enlighten…and drink. When combined, drunken enlightenment of others is also known as raconteurism. Telling a tale while wildly gesticulating, cocktail in hand, is the way we roll here. I seem to have gotten distracted. Where’s my drink?

Anyway, it would be more proper to describe a Thermos(TM) as a cheap commercial knockoff of a dewar. I’ll let the Thermos(TM) wikipedia article defame them properly for me. A beverage container that was a vacuum no better than a tenth of an atmosphere is hardly better than the old styrofoam beer can cozies. They rely primarily on the coefficient of thermal conductivity of select, proprietary insulating materials (usually a styrofoam-like substance) to minimize thermal transfer from the ambient atmosphere to your drink. Ah, I may have lost you there.  Let us take a trip down High School Physics Memory Lane. Please make certain you are wearing pants before wandering the hallways and classrooms of yesteryear…*BEGIN WAVY LINES OF FLASHBACK*

There are three ways to transfer heat from one body/location to another. They are conduction, convection, and radiation. As we flip to the end of the chapter of definitions:

Conduction: transfer of heat directly from body to another by molecular motion. This is entirely dependent upon the physical/chemical properties of the materials in question on how well heat transfers from one body to the next.
Convection: transfer of heat by mass transport of warm fluids/gasses mixing with cooler ones. See Also: your oven (no, not your mom.  I know you were expecting that joke though)
Radiation: transfer of heat by the emission of energy from a warm body as electromagnetic radiation (i.e. light).

Now, let’s review why dewars keep things at a constant temperature, not just cold. To the extent that you can reduce the three modes of heat transfer, you keep whatever at its starting temperature longer. The whole point is to keep temperatures as constant as possible; this is why another term for a dewar is “cryostat”. If it is hot coffee, it stays hot. If it is a frosty Manhattan, it stays refreshingly cold to the last drop. How does it reduce the transfer?

  1. It is made of two layers of material that are very good insulators (don’t conduct heat) with a seriously hard vacuum in the space between them.
  2. It comes with a lovely insulating foam lid.
  3. It is silvered on all possible surfaces containing the fluid.

Good scientific grade dewars are built of borosilicate glass which is fairly good about not conducting heat compared to metal and plastic (see also: most beer cans and cheap thermoses), reducing heat transfer by this route. Similarly, you need a vacuum to prevent both conduction and convection; if there is nothing there with which to conduct heat or convect, then you won’t have conduction and convection in those directions. Good quality scientific dewars will have a vacuum at least as low as .0000001 atmospheres of pressure, as opposed to the 1 to .1 atmospheres most Thermoses are (an atmosphere is defined as the outside air pressure at sea level at standard temperature, 68°F, and 20% relative humidity). The silvering is to help reflect all energy that your fluid could be absorbing from or emitting to the outside world, reducing radiation. Really, the only direction to thermal transfer via convection of warmed or cooled air, conduction to the air/fluid interface or radiation into open space is straight up from the top of your fluid. If you slap a decently insulated lid on top, well, you haven’t eliminated all of those but you’ve reduced them as much as you can such that you can still drink your beer.

How well does all this work, you might ask? At sea level, liquid nitrogen (AKA: LN2 for people in the biz) exists as a -196°C/-321°F fluid; it readily boils off in seconds when poured on the normal room temperature floor, which tends to crack the floor tiles and makes the maintenance staff grumpy. As a cryotech, I am very familiar with the situation where a bench top dewar by is sitting on the counter filled with LN2, lid on, and will still have LN2 in it three days later… much to my surprise when I bumped into it by accident.

THAT is why I use dewars to make these steins.
