Hope this isn't considered heresy. I've been drinking good scotch for a while in its many incarnations, but generally in the 80 to 86 proof range. I bought a bottle of single cask Islay from Royal Mile Whiskies at cask strength (60%). Conventional wisdom is that yo add a few drops of water to open the flavor. I did the math and, in order to bring the 60% to a more "normal" range I would add half again as much water as whisky. so one ounce 60% whisky pluse 1/2 ounce water = 40% whisky.

I tried it, it tasted fine, and my 750 ml bottle will now go half again as far. Does anyone else do this? Who drinks their cask strength whisky straight?
