As for the Ardbeg, there may have been something wrong with it. I don't remember the taste exactly and I couldn't identify it at the time, but let's say it was like chlorine or some other chemical taste.

I like various types of Glenlivet, Glenmorangie, Lagavulin, Caol Ila and more, so it's not like I'm averse to peaty, or non-peaty...

I really thought it had been contaminated. I don't know it there's any record of such a thing happening. I tried to google it but didn't find anything.
