I get mine imported from Atlanta when I make a trip there or when friends come to visit. If you are after the high alkeehaul stuff I also recommend Chimay Blue (9%), available at Publix in Atlanta. If you see these words on a beer bottle
Barleywine
Imperial
Dopple
Dubbel
Eisbock
Strong
Tripel
Malt Liquor
you might want to have a designated driver available.
Now we're getting into the high gravity area of beer, which is different that stouts. It can get very dangerous when you drink these. You think to yourself "self, I'll just have the same amount of these that I typically have of my regular beer, and it'll be just fine." Next thing you know you'll be having butt sex with a homeless person in a dark alley.
But, I digress, and highly recommend purchasing a bottle of "Three Philosophers" if you are going the high gravity route. Smooth finish without too much bitterness. Chances are if you like the stouts and want to try something similar, you will make your way to higher gravity beers with a higher APV.
If any of you make it to the Georgia version of Decatur, there is an excellent pub called the Brickstore Pub that has hundreds of high gravity, Belgium beers that taste great and will absolutely fuck you up. First one's on me, but you're on your own when you start mounting the homeless.
