Abita brewing company 20 miles North of New Orleans, LA, one of the fastest breweries in America makes this stuff.
http://www.ratebeer.com/beer/abita-andygator/3/ My friend works at the brewery and employees get 2 free cases a week of whatever brew they like, and higher up employees get free kegs and such. The legendary and elusive and whispered about concoction of "Andygator" was a high ABV brew made SOLELY for employees. You could only get it through employees at the brewery and it came in mysterious brown unlabeled bottles with a steel cap on top, no mention of where it came from or anything. But after one sip you knew it was Andygator. Due to the leak of this brew they started bottling it -- in large bottles only -- you can find it in Fresh Market and Whole Foods and such. The original brew was 13% ABV when it was for employees only, it got stripped down to 8% ABV for the public market, but will still screw you up after only a few, and it will hit you hard. Good stuff, and great beer company, love all their stuff.
