Goose Island declined to offer further information Thursday, but in a statement, brewery President Ken Stout said, "Bourbon County Stout is a brand that represents 25 years of inspiration, perspiration and dedication. While we couldn't have anticipated what we've dealt with around the 2015 Coffee and Barleywine BCS variants, we have taken our learnings from this process and are using it to become an even better barrel-aging brewery moving forward. We'll continue to share our findings with other breweries, and of course, our BCS fans."
