If you asked whisky drinkers what their primary association is with Glenmorangie these days, my guess is that they would say 'cask finishes'. They have become far more prolific in recent years, but Bill Lumsden has been churning them out for decades now.
This whisky used to be a part of the distiller's core lineup in the early-2000s, but was later replaced with the 18 Year. It's made from ex-bourbon cask whisky that was finished in new oak for an indeterminate amount of time, then bottled at 43% with chill filtration and possibly coloring.
Thanks to Michael Kravitz for splitting this bottle with me.
Glenmorangie 15 Year
Nose: mostly oak - but not too sharp, gentle floral malt, caramel, honey, lots of vanilla, a little chipotle pepper, cacao, fresh vegetation in the background. After adding a few drops of water more caramel comes out but it is flatter overall.
Taste: rather sweet, balanced malt/oak, caramel, not very tannic, vaguely fruity throughout. After dilution it is similar but flatter.
Finish: sweet, oak, malt, grapefruit
I'll admit to being a bit disappointed by this whisky. I was hoping for something like the Original, but with more refinement and complexity from the extra age. While I wouldn't say that the virgin oak finish ruined the whisky, it did overwrite a lot of the more subtle character that I like in a Glenmorangie. So all in all, I can't say that I'm sad to see the end of this (small) bottle.
Check out Michael's review from the same bottle for a slightly more positive take.
