Lagavulin. The standard 16 year old is awesome, the 25 and 30 year old special bottlings I picked up in the UK even better. Like Laphroig, this Islay is very much an acquired taste, with an even more pronnounced iodine aftertaste. Macallan 25 ain't shabby at all either.
Best single-malt Scotch...
I have to give credit to Redwiki for the inspiration to start this thread. Yes, certain malts better compliment certain music or certain moods. Of the fifteen or so different malts in my cabinet right now, my favorites are: Aberlour "Antique", similar to the popular Macallan, but not as syrupy; a bit drier, light hearted and less complicated; great with Mozart and Brubeck. Mortlach "Limited Edition" cask strength. Powerful, smoky, mysterious. Great with Bartok, Berg and late 'Trane. Loch Morar 25 yr old. Incredibly complex and intense, with a hint of honey and flowers. Great with Poulenc, Stravinsky and Bill Evans. Any other single-malt aficionados out there?
