Rare Perfection 15-year is interesting, to say the least. There are certainly things I loved about it, and others I was a bit unsure about. However, when I let this pour rest a bit I did find that the nose really opened up and revealed some very pleasant and unique notes. Further, while the viscosity was almost too much at times, I found that a few drops of water really helped to thin it out and allow more of those sweet and smoky flavors to develop on the palate. Although this is a great whiskey to enjoy neat, I can’t help but wonder just how incredible it would be in a cocktail. Might I suggest you give it a taste neat, then with a bit of water, finally mixed into a Manhattan to see what happens!
