Well, here it is... whatever was "wrong" with Laphroaig 15 (which I always liked... and strangely enough I have no formal notes on, gonna have to fix that), the 18 is here to replace it.  And a lot more expensive too.  Let's see...

Smoke on the nose is immediate. Dusty. Bazooka bubblegum. Light caramels.  The palate is tamed smoke, medium-sweet. Medicinal aspects are present but not overwhelming.  Light fruits.  The finish is very long, and peaks after a moment, being where the 48% is most noticeable.  If you weren't a fan of the 15-year, then this probably won't do it for you -- although the ABV does keep it rather punchy, it's nonetheless still rather refined and elegant flavor-wise.  I actually find it rather similar to the 15, it's kind of like they just turned up the volume somewhat.  Makes a great peated digestif.
