I highly recommend Talisker if you like the peatiest/smokiest Islay malts. The distillery is on the coast of the Isle of Skye, and must have a similar ocean climate. The character is very similar to something like Lagavulin. Talisker doesn't seem to get as much attention as the distilleries on Islay, but it is right up there with them if that's your type of Scotch.Of the three the only one I still haven't tried is Lagavulin...I don't know if the Ron Swanson character made it so popular that it sells before I find it or what.
Yeah, I love Laphroaig, too. Awesome stuff. But Lagavulin is pretty sublime IMO, too. And I bet 'Ron Swanson' drove up the interest and maybe the price a bit.
