I saw this handy graphic on the Brookston Bulletin and it really shows where the breweries are no matter the methodology in getting there. There are some empty holes on the map that need to fixed! (Especially if I want to ever finish my quest to have a beer from each of the 50 states) Thanks to Brooklyn Growler for putting this together.
P.S. Click on the graphic to enlarge it.
It should be noted that this map shows the number of breweries per 100,000 people. I was looking at it wondering how the hell Iowa was as big as Minnesota until i noticed that.
The size of the circles do roughly correspond to how I perceive the strength of the craft beer scene across the country though, so that is pretty interesting.
At the rate that new breweries are coming, this stat will have to be changed a bit. It will be interesting to compare it year to year.
