Interesting that it's such a young crowd in here. I'm 31 now, I had been drinking Chivas 12 for years but didn't get into the single malts until about 2 years ago. Not interested in Chivas anymore!
The single malts I've had in this time:
Talisker Distiller's Ed
Laphroaig Quarter Cask
Balvenie 14 Golden Cask
Balvenie 15 Single Barrel
And there's a LONG list of those I'd like to try! Glenlivet Nadurra and Aberlour Abunadh are next on the list, both cask strength and sound like great values!
