According to wikipedia:A brewpub.
A microbrewery is just a brewery that produces a small amount of beer, it's an industry term.
Wikipedia said:A "brewpub" brews and sells beer on the premises. A brewpub may also be known as a microbrewery if production has a significant distribution beyond the premises - the American Brewers Association use a fixed 75% of production to determine if a company is a microbrewery.[4]
According to wikipedia:
Is there a special name for it?
I mean a pub that's physically attached to the brewery. I think there's one connected to the Fuller's brewery in London (The Fox and Hounds).Are you talking about a tied house? i.e. the opposite of a free house (a pub that has no affiliations with a brewery and so can sell any suppliers products) in pub terms?
A pubery. (pronounced 'pew-berry')
