The brewery=* key is used together with restaurants, bars, pubs and similar features to name the brands of beer that are served or sold at the location, whether on tap (draft beer/draught beer) or by the bottle.
How to map
The common syntax is: brewery=<name_of_brewery>. (e.g. brewery=Krombacher where the beer comes from
Krombacher Brauerei).
If it is selling beer from several breweries, you can use a semicolon to seperate them: brewery=<name_of_brewery>;<name_of_brewery>
Significant usage is also as a property brewery=yes/no to indicate whether a place has a brewery. This is incorrect. microbrewery=yes is the correct tag for this designation.
The value brewery=various should only be used if a very large number of beer brands are offered and this would not justify the effort of listing all brands. As a rule, this is the case with five or more.
Tagging examples
Additional tags
Subkeys
If the different special kinds of beer are sold from different breweries, tag like:
brewery:<kind_of_beer>=<name_of_brewery>, brewery:<kind_of_beer>=<name_of_brewery2>
E.g., brewery:weizen=Paulaner, brewery:pils=Jever.
Brewpubs
A pub which brews beer on site is called a brewpub, and can be considered a kind of microbrewery. Such a pub is tagged with microbrewery=yes.
A brewpub's beer might be sold only for consumption on the premises, or packaged for retail (off sales), or sold elsewhere as well.
Taprooms
A pub focused on craft beers, usually has multiple taps of several beer styles. Such a pub is tagged with drink:craft_beer=yes.
Unlike brewpubs, in a taproom doesn't brew on the premises.
