- 1 tsp
Irish Moss - (omitted from calculations)
Irish Moss
A dried red-brown marine algae. Fining agent to remove large proteins. Negatively charged polymer attracts positively charged protein-tannin complexes (extracted from grain husks and hops) during the boil. This action is aided by the clumping of proteins in the boiling process. Irish moss settles to the bottom of the brew kettle with spent hops and hot break material at the end of the boil.
- .5 tsp
Wyeast Nutrient - (omitted from calculations)
Wyeast Nutrient
Although wort is a good growth medium for yeast, additional Wyeast Nutrient will reduce lag time, improve yeast viability and provide consistent attenuation rates. Low assimilable nitrogen concentrations (FAN) of grape must or wort have long been known as a cause of sluggish or stuck fermentations. Wyeast yeast nutrient, a blend of vitamin B's, minerals, inorganic nitrogen (DAP), organic nitrogen (amino acids), zinc, phosphates and other trace elements will benefit yeast growth and carbohydrate uptake for a more rapid, complete fermentation. Use 1/4 tsp per pint for beer propagation, 1 tsp per 5 gallons for wine or beer fermentation or 1.5 oz per 10 barrels for beer fermentation.

Holy living f@#% that's a bitter glass of beer! I'm jealous of your resources and deeply impressed by your patience, I'm not sure I could endure a year of aging. It must have been a very special occasion when that monster was decanted. 342 IBU. Wow, fine work.
The best ever.

You cannot believe the IBU calculation. Beertools doesn't allow for the fact that the solution can only hold so much iso-alpha acids. The IBUs are probably around 125.
The best just got better.

I extended the boil time and made a couple of small changes to the hops. If you want the details, just ask.
I have posted changes to the library.

This is a moderately expensive beer to brew, but you cannot get a beer like this from a store or brewpub--they can't afford to brew it. It will cost you about $60.00 to make 5 gallons. But, it's a prize winner and a terrific beer.
