Big Sky Brewing Co.’s Missoula Five-O Chocolate Coconut Imperial Porter clone

Big Sky Brewing Co.’s Missoula Five-O Chocolate Coconut Imperial Porter clone

(5 gallons/19 L, extract with grains)
OG = 1.089  FG = 1.018 IBU = 15.4  SRM = 35.8 ABV = 8%
Recipe was created by Zoo City Zymurgist member Bill Ruediger, who won the Community Brew contest hosted by Big Sky Brewing Co. The winner of the contest brews a commercial-sized batch at Big Sky. The beer’s proceeds were donated half to the brew club and half to a charity of the club’s choosing. Bill’s winning beer was inspired by a chocolate coconut porter at Maui Brewing Co. fresh off the taps. It took him eleven batches to finally find the winning combination.
