Stone 11th Anniversary Ale Recipe
90% pale malt
5% 60°L Crystal
5% Weyermann Carafa III Special
OG target is 20.5°P (1.082 SG) Terminal Gravity target is 4°P (1.016 SG)
Bittering at start of boil: 100% Chinook
Flavor hops added at end of boil or whirlpool: 50/50 blend of Simcoe and Amarillo
Target 120 IBU’s.
Ferment with good ale yeast. We used our house yeast.
Dry-Hop with 50/50 blend of Simcoe and Amarillo, use LOTS! (we used 1 ½ pounds per barrel).
The carafa and the Crystal can just be steeped, no need to mash. Now just convert the pale malt to pale DME (Again, a good rule of thumb is 1.0lb malt = 0.67lb DME).
I should be in bed so I cannot do the math right now but you need to figure out exactly how much of everything you need... using www.tastybrew.com/calculators/recipe.html
I would guess that, for a 5 gallon batch with a 3 gallon boil, maybe:
12lb Light DME
0.67lb Crystal 60
2.25 oz. Chinook at 60 minutes.
That looks like it is about right. Or I could be horribly wrong. If I am right, that is an awful lot of DME ($$$). Maybe time to do a PM?
