Ha thats awesome you picked the brown... I converted it today!
Here's what I got
Type: All grain Size: 5 gallons
Color: 33 HCU (~16 SRM)
Bitterness: 21 IBU
OG: 1.055 FG: 1.011
Alcohol: 5.6% v/v (4.4% w/w)
Grain: 8 lb. American 2-row
2 lb. American Munich
.5 lb. Belgian CaraMunich
5 oz. Belgian Special B
1 oz. American chocolate
Mash: 70% efficiency
Boil: minutes SG 1.039 7 gallons
Hops: .5 oz. Kent Goldings (5% AA, 60 min.)
.5 oz. Fuggles (4.75% AA, 30 min.)
.5 oz. Kent Goldings (5% AA, 15 min.)
*These aren't the same hops they use bc I'm not exactly sure what they use plus I've got a pound of each...Also, I think the timings need to be redone...like only 60 and 30min hops since it's a brown...just as long as it's around 20-25IBU's
First off, I used this to convert/write the recipe
http://hbd.org/cgi-bin/recipator/recipator
Next, 1 barrel is 31 gallons (or is it 33?) so those recipes are for like 1025 gallons!
Ok and lastly...for extract just steep all of the specialty grains (does munich have to be mashed or can it be steeped? Not sure) and convert the 2row to extra light DME
The equation is (pounds of 2row)X .6875=(pounds of DME)
Hope that helps
