Grain whiskies get a bad rap in the scotch whisky world, but that's why an accomplished blender like Compass Box set themselves the challenge of debunking that perception. This is a bravura performance from John Glaser, Compass Box's mastermind. I just criticized Compass Box yesterday for having some mediocre blends, but this is not one of them. Hedonism is a bit one-note, but the note is spectacular and clear, and Glaser deserves credit for purifying it to this point. Hedonism tastes exactly like vanilla, more than any other whisky I've ever tried. It is like a vanilla-heavy bourbon, if you then stripped out the toffee or caramel notes. It is like hearing a perfect, pure note from a well-tuned piano or violin. It's beautiful to behold. The finish reveals some aged oak lurking in the profile, but that vanilla is the absolute star here, and it's virtually a one-man show. It's a credit to Compass Box that the one note not only keeps my attention, but captivates it.
