Milwaukee's history is as beer-drenched as any city's in the nation — its baseball team is the Brewers for heaven's sake — but it has been curiously late to the national rise of small and local breweries. During the past decade, the number of breweries in the U.S. has climbed from 1,500 to about 6,500. Craft beer's share of sales rose from less than 4 percent of the industry to more than 12 percent.
