http://en.wikipedia.org/wiki/Three-tier_%28alcohol_distribut... "States have various exceptions to this rule, the most prevalent one being the case of a brewpub, which is simultaneously a producer and retailer, and has no requirement to sell to a distributor. Some states allow an entity to have a part in two of the tiers, letting small breweries act as their own distributor, for example. Many states permit wineries to sell bottles of wine on-site to customers."
