From an article in the WSJ...
You know the beer drinkers have won when you can fill your growler with local craft beer at a drugstore.Well, now. Howzabout THAT? I've been known to fill a growler or three meself, and yeah... we do like to drink locally.
The craft beer craze isn't slowing down, and as the number of breweries grows, so has the popularity of growlers—64-ounce reusable jugs that can be filled to take off the premises. With growlers, you get fresh beer. Often it is beer that is not available in bottles or cans. And you get it in a local, environmentally friendly way.
There are now as many breweries in the U.S.—2,500—as there were before Prohibition, which ran from 1920 to 1933, says Julia Herz, craft beer program director of the Brewers Association, a trade group based in Boulder, Colo. Survey data from the Brewers Association suggests that most craft beer drinkers are young, male and wealthier than average: More than 77% of craft beer volume is consumed by people who make more than $50,000 a year. Surveys show they prefer beer brewed locally to mass-produced, bottled options.
