Ever tried "KULMINATOR" Eisbock from Germany??! It has around 9% Alcohol (this is no fake). In Winter they let the barrels freeze so the alcohol is concentrated in the middle. Nothing for sissies. The taste is a disaster, but you do not realize that anymore after drinking the 3rd. bottle.
I had a Dutch beer called "THE MAXIMATOR" that sounded similar to this. Sold in single, oil-drum type cans. After about four of them we were having so much fun saying the name of the beer with a Schwarzeneggar/Hans and Franz accent that we'd forgotten it tasted like vomit.
