Schmidt Ice
We got a ton of this one winter for 3 bucks a 12 pack. It was almost undrinkable. Here is the trick. It was a really cold winter in Bozeman MT so we would take a case and put it on the back porch. Then after it sat outside for a long time we would grab one and drink it as fast as possible, but once your hand touches the can it will start to warm up and if you don't get through the whole can in the first pull just toss the rest it will be tough to finish. The key is getting it really cold and drinking it fast before it warms up. Ice I think is actually a serving suggestion as opposed to a production technique.
