Gordon & Macphail just released, I think, a series of malts showcasing the various distilleries they own around the place from each region. I've only had the Highland, which is 7 or 8 year old Highland Park, but it was really great. Their Islay is 7 or 8 year old Bunnahabhain, which to me is one of the hidden gems of Islay. That will probably be my next "budget bottle."
When I'm feeling rich, I drink Talisker, which I got as a birthday gift, or my favorite, Laphroaig Quarter Cask.
I just got a bottle of this not too long ago, and it's amazing how different it is from the 10/15. Amazing. Even though I love a nice peaty peppery 10 or 15 sometimes, I generally prefer the Quarter Cask at this point.
EDIT - I also want to put out the notion that too much emphasis is put on age, as if an 18 is going to be infinitely better than a 12 of the same malt. To me, that's preposterous. I could drink 12 year or under whisky for the rest of my life and have a fine time of it. I mean, don't get me wrong, I love Macallan 18, and I love Highland Park 18, and I love all kinds of them, but I'd rather have three 10 or 12 year old bottles before one 18 in almost every case.
+1
That said, at least in the case of the Macallan, while the 18 is a lot more expensive than the 12, IMHO it's worth it, because to me it seems a LOT smoother and richer. Love that. However, I always have a bottle of 12 on hand, as a "regular drinker", and it's also a truly great scotch... no doubt!
