I've not noticed it, but I don't (as has been noted) drink much Scotch.
(And, yes, +Margie Kleerup, I looked it up, and the same can occur with certain toasted wine barrels used for some chardonnays.)

FYI: Why Does Scotch Smell Like Band-Aids?
Also disinfectant, crude oil, Sharpies, synthetic insulin…

I always thought it smelled like Iodine.
Actually, the peatiest is another Islay mal, Bruichladdich’s (80.5 PPM) malt with the name ‘Octomore’. I can’t recall if I have bought any of this!
Sharpies, ick! Don’t smell a bit like my Islays, for which I’m grateful. If you should hear of anthing that reminds the taster of tea-tree oil or any other melaleuca, let me know so that I can avoid it for the sake of my health.
