A brewery is a building, where beer is made or a business (brewing company) whose trade is the production and sale of beer.
Breweries can take up several city blocks, or be a collection of equipment in a homebrewer's kitchen. The diversity of size in breweries is matched by the diversity of processes, degrees of automation, and kinds of beer produced in breweries. Typically a brewery is divided into distinct sections, with each section reserved for one part of the brewing process.
