Famous for being the whisky with the highest peat concentration in the world, Bruichladdich’s Octomore series reaches edition 6.3 with this 2015 release. The USP of this particular whisky is that all of the barley used to make it was grown at the local Octomore farm that gives the series its name. Not only that, but a small label on the bottle even states the specific field it was grown in; now that’s dedication to provenance.
