Octomore is Bruichladdich's limited edition range of ever popular super peated whiskies; some of the most peated whiskies on the entire planet! Octomore 03.1 is aged for 5 years and made with malt that has a phenol content of 152 ppm (parts per million). To place that into perspective, 40-60 ppm would usually be considered an intensely peated Islay whisky.
