If you don't count open bottles, very little. Mostly Eagle Rare 101, I think I have five of these unopened. One AAA 10 year old, two AAA ten star that I bought thinking it was the ten year old. Since I really liked it I wasn't disappointed. One OGD BIB that I just haven't gotten around to. And a few bottles of Scotch, Irish, and Japanese whiskies that I haven't opened because I drink bourbon so much more often.
Basically, everything I buy gets opened either the evening I buy it or within a few days of getting it. Unless it is something that I won't be able to replace, then I buy a few bottles.
