This is an interesting old Ben Nevis. High marks for complexity, though I didn't find all the flavors very pleasant.
The nose is classic Ben Nevis with the funky sourness that we all know, and some of us love. It's on the palate that things get a little off track in my opinion. Again the classic Ben Nevis profile is there, but it is accompanied by some soapy wet cardboard flavors with I don't care for.
I would definitely recommend that Ben Nevis fans find a sample if they can, but try it before spending this much on a full bottle.
