At 307.2 PPM, Octomore 15.3 is our second most heavily peated release to date. Using 100% Islay barley, matured in bourbon casks and Spanish Oloroso hogsheads. Formidable smoke is countered by ripe fruit from its patient distillation.

From OCTOMORE EDITION 15.3 -BRUICHLADDICH DISTILLERY COMPANY official site-

I think I once bought an Octomore for home drinking. I remember being amazed that I could “relive” at home the peat shock I first experienced when trying Octomore at a bar (￣▽￣). If you’re interested in this whisky, definitely give it a try. However… if you plan to taste several other whiskies, I recommend saving this one for last. If you drink it first, the flavors of the whiskies you try afterward will inevitably seem weak and muted for a while.
