A growler (US) (/ˈɡraʊlər/) is a glass, ceramic, or stainless steel bottle (or jug) used to transport draft beer. They are commonly sold at breweries and brewpubs as a means to sell take-out craft beer. Rarely, beers are bottled in growlers for retail sale. The significant growth of craft breweries and the growing popularity of home brewing has also led to an emerging market for the sale of collectible growlers. Some U.S. grocery stores, convenience stores, bars and restaurants have growler filling stations. http://www.qanthermos.com/growler/
