Tried my first bottle (not the whole thing honest) of Black bottle this weekend.
It wounds me to say it but I really can't help feeling that the grain dominates too much in this and all the cheaper blended scotch whiskies.
I was having an Islay afternoon - Black Bottle, Ardberg 10YO, and some Safeway's Islay (a vatted supermarket malt that is very good).
Bottom line: malt tastes better than grain in scotch no matter what the expression (imho).
The only blend that really cuts it for me is JW black label.
Cheers,
Bamber.
