This year's 13.1 release is peated to an insane 137.3 parts per million, which—to give you some context—is roughly quadruple the amount of peat you'll find in Lagavulin 16. Aged entirely in ex-Bourbon casks and distilled from 100% Scottish barley, the vanilla from the American oak and the creaminess of the malt provide a striking contrast to the salinity and brininess of the whisky, to say nothing of the smoke!
