A bar or parlor in Plymouth where brewers prepare their own beer and serve it on the premises, is known as a brew pub. A brew pub may also be referred to as a 'microbrewery', if the production has a substantial distribution beyond the premises. In the earlier times, most of the traditional pubs that brewed their own beer in the brew house at the back of the pub, were bought by larger breweries and the brewing on the premises was ceased. Generally craft beer is brewed for sale in restaurants and bars in Plymouth. In lots of brew pubs in Plymouth, beer is often distributed directly from the brewery's storage tanks through the taps.
