So PizzaPlanet and I got some cask strength Tasmanian single malt whisky while on the road, and since PizzaPlanet isn't much of a whisky drinker I have a lot of it left over. I am now enjoying a glass of the peated bottle, undiluted at 68.1% alcohol by volume -- that's 136.2 proof, for you Americans. It's like getting punched in the mouth by someone with a fistful of peat, which is just the way I like it.
Edit: We actually visited a distillery and got to pour these bottles straight from the casks ourselves. It was totally awesome.
