Bosmo’s Imperial Cream Ale

This recipe by Rick Debar of the Barrel House Brewing Company and Ray Snyder of the Bloatarian Brewing League is from the May/June 2008 issue of Zymurgy magazine. Bosmo’s Imperial Cream Ale was developed as a joint project between the homebrewers and the professional brewers of Greater Cincinnati. The name is in honor of the Bloatarian Brewing League’s iconic mascot, Bosmo; but the style is a tribute to the long history of excellent relationships between the homebrewing community and the professional brewers of the area.

Cream ale was chosen as the base style, because it was popularized in Cincinnati. Some people think ale brewers created cream ale to compete with the new lager beers in the latter part of the 19th century. Others believe the German brewmasters in America simply applied their experience with German ales to create cream ale. Either way we’re sure you will enjoy it!
