Hi,
I've never had the pleasure of trying JWB, but having tried both the Black and the Red, I won't be investing
It's simply a matter of taste, I find the JW blends i've tried so far to be a little 'sour' for my pallete. Maybe I needed to try a couple more glasses to make sure?? ;-)
As a suggestion, try to source a miniature of the whisky before purchasing the expensive bottle, I've found it an excellent way of tuning my wallet to my tastebuds
Cheers
Bry
