A brewery that produces less than 15,000 barrels (17,600 hectoliters) of beer per year with 75 percent or more of its beer sold off-site. Microbreweries sell to the public by one or more of the following methods: the traditional three-tier system (brewer to wholesaler to retailer to consumer); the two-tier system (brewer acting as a wholesaler to retailer to consumer); and directly to the consumer through carry-outs and/or on-site taproom or restaurant sales.
A business that hires another brewery to produce its beer. It can also be a brewery that hires another brewery to produce additional beer. The contract brewing company handles marketing, sales, and distribution of its beer, while generally leaving the brewing and packaging to its producer-brewery (which is also sometimes referred to as a contract brewery).
A brewery with an annual beer production of between 15,000 and 6,000,000 barrels.
