The biscotti is there in the forefront but the peated whisky crushes that pretty handily in the aftertaste. The dark sweetness plus smoke gives a bit of a barbecue sauce vibe which was not what I was looking for when I picked this. Sad as a big fan of both smokiness and Averna together, Devil's Soul is one of my favorites.
I'm guessing your choice of whisky (and possibly cognac?) might determine if you get a "barbecue sauce vibe". I just made this with Camus VSOP Cognac & Laphroaig 10 Year, and I'm noticing any sort of barbecue sauce flavors.
