A couple of experiments, 'cuz I wanna Options

[BrewBasser]

1. To get a personal on hand view of the max IBU level attainable in a beer, I plan on doing a stovetop boil with enough hops and time to calculate out to the 200-300 IBU range and then have the lab analyze it and let me know what I got.

2. Brew, from grain, a single bottle of beer.

I will post relavent info as I get it.

Both sound like interesting ideas.

for #2 are you going to do all the fermentation in the bottle (like with a small cork and blowoff) then just prime and cap? Or ferment separately?

Oh i do this all the time! I use nice 5 gallon bottles. Just thought I would be the first wisenheimer to post the inevitable. Seriously though that sounds like quite the micro project. When I read BYO a couple mos ago about the minibatches I said "Why?" but just to say you did it would be kinda cool.

2. Brew, from grain, a single bottle of beer.

For #2, maybe primary in a bomber, secondary in a 1/2 litre, and bottle in a regular bottle w/ prime tab. 1/4 cup dme & a dropper of that hop soup your making in #1 should make a decent blond.

[BrewBasser]

The beer will be primaried in a 22oz bottle and secondaried in same, and will be then primed into a 12 oz. Well, at least that is the way I envision it at this point.

Pointless but fun at the same time.

so you guys have a mass spectrometer at sierra nevada? cool!

You don't need one to get the BUs, that is done with a UV spec, but yes we have several mass specs. Our lab is spectacularly equiped.

So, are things supposed to happen at a faster rate, in such a micro climate..or the same as doing 5 gallons?

don't know that i've heard of a uv spectrometer. are you looking at the fluoresence off of the uv? if so, what are the wavelength(s) that lupelin fluoreseces at?

either way, i'm jealous.

Not fluorescence, but absorbance in the UV range. I forget which wavelength 2 hundred something.... Should be easy to find.

Basically you take the beer, extract it with an organic solvent and then measure the absorbance at a specific wavelength and then apply a correction factor.

Naw, I just want to say that I brewed a single bottle of beer for the nerd factor. You know, party conversation...

And then when that single bottle of beer is gone let the heartache begin. It could be like that old fishing story about the "one that got away".... (IMG:style_emoticons/brewboard/biggrin.gif)

BrewBasser: Hey! I brewed a single bottle of beer!
party goers: Cool! Can I try some?
BrewBasser: sorry. All gone. (IMG:style_emoticons/brewboard/sad.gif)

OK,

So I semi did one of the experiments. I brewed some beer to see how accurate ProMash was at calculating BUs.

See, here I'm brewing beer

(IMG:http://img.photobucket.com/albums/v168/MolBasser/ghettorig.jpg)

It calculated out to 18.5 plato and 80 IBU in promash, and I got 17.6 plato (stupid corona mill.....I forgot to adjust my efficiency down after giving back my buddies roller mill) and it is in the lab right now. I am also getting a color calculation from the lab to match to what I got in ProMash.

ah....the curiosity. Once it is fermented out I will have it beeralyzed to get the finished IBU and alcohol content.

I saw this and immediately turned to find Randy Moshers book Radical Brewing because I remembered seeing this...


"Sometime, radical brews can be brewed from quite ordinary ingredients-in stupefying quantities. Nashville hombrewer Tom Vista has anointed himselfthe Hop God and if divinity were based on quantity alone he would surely qualify. If you were wondering how hoppy a beer can be, well, then just brew this one. Although the wort won't absorb much more than 100 ibu of bitterness, this calculates out at 473 ibu! And that's wothout the hops in the mash or in the sparge water."


5 gallons
1.070 o.g.
100 IBU


8lb maris otter or golden promise pale malt
4lb moravian pilsener malt
2lb biscuit/amber malt
1.5lb torrefied wheat
.5lb pale crystal 20L
.5lb medium/dark crystal 60L

mashed between 156 and 158 degrees F, between 1.15 and 1.25 qts/lb
hops can be added to mash and/or sparge water(doesn't give instruction or amounts but recommends pellets)

first wort hopping
4 oz. columbus (15%aa)
4 oz. flavor hop: cascade, liberty, crystal or willamette

standard hopping
4oz. centennial (10%aa)60 min
2oz. centennial or columbus(10%aa)45 min
2oz. centennial or cascade (10%aa)30 min
8oz. aroma hops, your choice(cascade-6%aa)15min
8oz. aroma hops, your choice(cascade-6%aa)end of boil

it states that "these extract figures are calculated for 7 gallon,not 5, as lots of wort remains trapped in the giant pile of hops."
also states that he used to dry hop it but stopped because the final additions seem to be enough.
