To be a triple oak barrel blend there is a surprising absence of wood on the nose. There's lots of sweet fruit and flowers with just a hint of oak and sherry cask. The oak waits until it rolls across your tongue, then it makes a big presence- vanilla and heavy spice. Just a tiny bit of raisiny sweetness before finishing pretty smooth like almost every Mac I've had. My notes lead me to believe the 15 is marginally better than the 10, and I wanna say the price point was only $20-30 more than the entry level of the fine oak series (the 15 was $70 IIRC). Unfortunately I don't have any 10 year laying around to do a proper side by side, but I'm pretty sure the 15 would win and be the one I'd recommend. I always recommend Macallan because they are the pinnacle of Highland/Speyside scotches IMO. Sadly, they know it and are almost always significantly more expensive than most of their neighbors. A lot of times though they really are worth it. Cheers.
