The layout of the local beer, wine and liquor is the result of the areas various temperance laws.
Local alcohol laws date are typically a mess of restrictions and prohibitions that probably have a variety of intended and unintended effects. Of interest to this website is how it makes beer and wine from 1000's of miles away easier to buy than beer and wine made and produced locally. The wine industry sees the biggest problematic restriction on being able to ship by mail order, and tiered distribution systems. The former means a small producer in MD can't ship to a consumer in VA. These restrictions that have stayed on the books generally are the anti-consumer laws that favor a particular business with clout in the legislature.
Local beer and wines usually is artisinal or premium and usually cost that much.
Alcohol is healthy in range of 0 to 1 drink per day, so please consume responsibly.
Expect to have to drive out to the producer to get local wine, or go to a brew pub to get local beer, although there are some stores that carry local VA wine, often smaller or upscale retailers.
