I used to HATE all of the sherry Macallans. My friends thought I was nuts. But they all have one common flavor that I found offensive. Before the Mac reached my lips, I could smell that awfulness coming. Then I somehow learned to taste it past that one thing, and love the other things it brings. That was thanks to a friend sharing a bottle that had been open for many months. It turns out that the offensive part of Mac burns off with air exposure. See, Mac is one of the distillers that uses a closed tun for mixing, and that keeps air away from it. Anyway, now Mac is one of my acquired tastes. Currently working on a bottle of Classic Cut 2017; a rare Mac at cask strength (58%).
