I have a recipe that was in BYO several years ago. I've brewed it a couple of times and it's reasonably close. This is an extract recipe so if you're an all grain brewer you'll have to convert it. That's what I did.
Big Sky Moose Drool Brown Ale clone
(5 gallons/19 L, extract with grains); OG = 1.052 FG = 1.013; IBU = 26 SRM = 38 ABV = 5.1%
2.5 lbs. (1.1 kg) light dried malt extract
3.75 lbs. (1.7 kg) light liquid malt extract
1 lb. 2 oz. (0.5 kg) crystal malt (75 °L)
5.0 oz. (0.14 kg) chocolate malt
0.33 oz. (9.4 g) black malt
6 AAU East Kent Goldings (60 mins) (1.2 oz./34 g at 5% alpha acids)
0.5 oz. (14 g) Liberty hops (5 mins)
0.5 oz. (14 g) Willamette hops (5 mins)
Wyeast 1968 (London ESB) or White Labs WLP002 (English Ale) yeast
Step by Step:
Steep grains at 154 °F (68 °C). Boil wort for 70 minutes, adding hops at times indicated. Reserve liquid malt extract for final 15 minutes of the boil. Ferment beer at 70 °F (21 °C).
