I finished off a bottle of first-run Baker's bottled in 1992. Man did that bottle drink well. There was only the slightest hint of sour astringency at the outset, but the weeks it had to air out completely vanquished any unpleasantness. It was by far the best Beam product I've ever had. I'll have to try a neat pour at a bar one of these days, but my impression is that the current bottles don't hold a candle. Perfect age, perfect proof, I'd love to find more!
