Macallan 18yo from 1974 (maybe)
Nose: Somewhat similar to the 12 with some Band-aids (or some other solvent) in the background. Not in your face, but noticeable. Sherry much less noticeable. The 12's nose is much cleaner...
Palate: A bit flat. None of the attack that I've experienced with the other two, but maybe the 18 is supposed to be like that. Don't have another 18 open to compare it to, and can't really remember my previous experiences with the 18. Nice enough sherriedness. Fuller than the CS with water. (The CS with water became a bit dodgy upon standing.

Huh??) Very engaging fruit. Some apples but without the tartness?
Finish: Very easy to drink. Fruity. There's a hint of bread or dough here too.
Overall: Nice enough but need to compare it to some other 18s before I render an opinion...
