I have never tried any J&B..
but in a liquor store recently, they had 50ml bottles of J&B JET, which I had never seen anywhere in Chicagoland before.. so I picked up a 50ml bottle for 2.99 to try eventually..
they also had 1, VERY dusty box for J&B Ultima.. at $149.99.. i guess this stuff was cancelled it 2001, so it has been sitting there for a good 4 years... apparently it was a special limited ediiton of J&B, anyone ever try it?
