The three-tiered beer distribution system can be a bit dizzying. Beer distributors act as the middle man between brewers and the liquor and grocery stores that sell the final product. They also provide transportation, refrigerated storage and maintenance, because producers do not sell directly to bars, liquor stores, or grocery stores. Who cares, right? Well, certain craft breweries are only able to distribute their beers to specific regions. After all, craft beer is best served in its local, where it's brewed. But with the advent of monthly beer clubs and specialty beer shops, more of us can get our hands on what we want: more great beer.
