I'm very grateful for that very detailed answer! The Whisky I bought was at about 40-50 Euros (Bought in Denmark), if that could be a hint. Didn't know that Bowmore was available as a provenance but I'm sure going to look for it now, since the original Bowmore is a great Whisky and I suspect that the Provenance whisky is even better.
I've tasted the Caol Ila and while I'm not thrileed about the original, the Provenance version is really tasty and good value for money. Never heard of the Port Ellen, but if it's rare I suspect it will be out of my financial reach, cause even if a whisky is great, I have an upper limit at about 50 Euros for whisky.
Thanks once again for this answer, now I know what to look for!
