Caol Ila single malts are definitely in the peaty, Islay style. But their core offerings are notably lighters and less smoky than most of the other Whiskies produced on the island. In fact, they even offer a non-peated "Highland spirit" just to prove the point. But that is an exception.
What you will notice first in their signature 12 YO dram is a whiff of peat on the nose and palate with the flavor of light summer fruits and a bit of toffee. The finish is generally warm and inviting to another round. We consider Caol Ila to be a good introduction to peated Islay Whiskies for the uninitiated.
