The clone recipe in BYO is a bit different, not sure if it'd make a huge deal:
OG = 1.075; FG = 1.019; IBU = 35; SRM = 13+; ABV = 7.2%
15 lbs/6.8kg pale malt
0.25 lb/110 g roasted barley 300*L
6 AAU Kent Goldings @ 90 mins = 1.5 oz/42g @ 4.4% α-acids
5 AAU Kent Goldings @ 30 mins = 1.25 oz/35g @ 4% α-acids
Wyeast 1728 @ 2.25qt/2.25L starter
0.75 cups corn sugar for priming
Heat 19 qts water to 163 F / 73 C; crush grains; mash in.
Hold at 152 F / 67 C for 60 minutes.
Put first gallon into heavy pot and boil it hard for 30 minutes, stirring often.
Collect a further 7 gallons of wort and start the boil, which will last about 2 hours.
When you have 6.5 gallons of wort and ±90 min left in the boil, add caramelized wort and first hop addition. Add remaining hops @ 30 mins. Cool to 68 F, aerate & pitch. Primary @ 8-10 days at 65 F, transfer to secondary and condition at 50 F for two weeks. Age in bottle for 8-10 weeks.
