The Southern Tier Brewing Company in New York just made a new beer called Thick Mint . . . which is a high-alcohol stout that's brewed with cocoa and mint to taste like Thin Mints.
Now . . . the beer isn't officially sanctioned by the Girl Scouts, but it dances around a trademark violation just enough that you should be able to get your hands on it if you want to try it. You can find where it's for sale near you at STBCBeer.com.
