A funny-tasting pint is often not a brewery's fault. Off flavors are often caused by dirty draft lines, which can harbor bacterial growth. According to the Brewers Association, draft lines should be thoroughly cleaned every two weeks. If your beer tastes strange, ask the bartender about the bar's cleaning regimen. If he doesn't know, then ask for something bottled. Another tip: To better your odds of scoring clean brew, ask which beer is the most popular. The beer with the highest turnover is the most likely to have the cleanest lines.
