A microbrewery or craft brewery is a brewery that produces a small amount of beer. Exact definitions vary, but the terms are typically applied to breweries that are much smaller than large-scale corporate breweries and are independently owned. Such breweries are generally characterized by their emphasis on quality, flavor and brewing technique. The microbrewing movement began in the United Kingdom in the 1970s — although traditional artisan brewing existed in Europe for centuries — and subsequently spread to other countries. As the movement grew and some breweries expanded their production and distribution, the more encompassing concept of craft brewing emerged. A related term, “brewpub”, refers to a pub or restaurant that brews its own beer for sale on the premises.
