Lloydelee, I completely agree about the Macallan 18 vs the 25. I have been saying the same thing for some time and gotten frowns from some friends. I have always felt the 18 is THE ONE.
Recently received a gift of Macallan "cask-strength". No indication as to age. I am a fan of cask strength malts, but while this is interesting and I do enjoy it, I find it surprisingly rough and syrupy even with a couple of drops of water (spring, of course) added to relax things. Disappointing overall.
Far more interesting and one that I never would have guessed I would enjoy as much as I do (given my past experience with non-Scottish single malt whiskies, particularly Japan) is the Amrut "Fusion" from (are you ready?) India! I know , I know.... But, a very interesting malt with lots of spice and chocolate notes. Very reasonably priced too. Recommended!
