Re: J&B Ultima
Definitely 'worth a go' as far as I'm concerned. But you have to be a believer in the whole concept of blended whiskies to really enjoy it.
This was, as far as I'm aware, a '1-off' melding of 128 different malt and grain whiskies. It's certainly a fine pour, with a lot of subtleties emerging as you sip your way through it. Smooth as silk, too. A real class act!
