The craft beer world is dotted with provocative names and labeling, but a rising outcry that some aren’t so much racy as they are offensive may lead some in the industry to rein in those tactics when hundreds of breweries take part in this year’s Great American Beer Festival. The Brewers Association, a Boulder-based trade association that hosts the festival, has updated its advertising and marketing code, placing restrictions on the marketing of beer with brand names and labels seen as sexually explicit, lewd or demeaning. The reaction within the beer community here in Colorado, a state with the second-most craft breweries per capita, has been mixed — some wish the rules went further, and others think the association is digging itself into a hole.
