It's beer. No, it's coffee. OK, how about a Redhook beer with Starbucks coffee? In one of the more unusual amalgamations Redhook Ale Brewery said Wednesday it will offer a Double Black Stout that adds Starbucks coffee flavoring to a beer. Initially the beer will be sold only on draught in Seattle, where both companies have their headquarters, as well as in the Portland area, but there may be bigger things ahead once the brew gets to bottle next month. Anheuser-Busch has rights to distribute Redhook's brews around the country, but that brewer had no immediate comment on its plans.
