The best I’ve had was a 40yo. A friend, who hates whisky, had it bought for his 40th and kindly brought it along on a winter climbing trip. I hate whisky aswell, but happily necked this one. It was significantly less horrid than any other single malt I’ve ever disliked. Can’t recall what it was tho, but very nice(ish).
Wine, I’ve had a Penfolds Grange 1998, those in the know will know that is something very special, particularly 1998, and it was. Also had an old Paul Jaboulet La Chapelle, don’t recall the year, but quite old and absolutely stunning.
