Quoted from TheFamilyArcade:Laphroaig for me. Briny and distinctive. 15 year old is great but 10 year is just fine. I prefer the Islay style, but there's quite a few scotches out there that are pretty damn tasty.
I like the peaty Islay style too! Lagavulin 16 is my fave if I have the cash. Its Laphroaig's smoother cousin.
