Amazing! It absolutely is better than any of the three stouts it is inspired by, it's the best stout I've ever had by a country mile. Some people may say it's a little too sweet at frist with lots of caramel and licorice before some balsamic takes over. After this initial sweetness a smokey coffee like taste comes across, you can definitely feel the alcohol but you certainly can't taste it which is the main thing for me. It certainly warms you up, maybe too much as I'm getting a tad warm as I write this. Unusually for a stout there appears to be significant hopping to this beer, and by their bite you can tell they are of excellent quality, I would suggest the Norwegian brewery, Nøgne Ø, produced these hops. The finish is very thick and has elements of the aforementioned dark fruits and bitterness from the chocolate and something that reminds me of aniseed. My words definitely haven't done this beer justice, there is just far too much going on to describe. Incredible!
I will leave you with more words from the commemorative box, which I feel sum up this beer perfectly. "A chorus of non-conformity emerges to venture down a path untraveled. With loads of dark malts and prodigious hops, this ultimate imperial stout yields an aura of mystery and adventure, inspiring imaginations and challenging convention and jaded orthodoxy. This is an unearthing; this is the Black Tokyo Horizon." And it's absolutely Brilliant! Simply the best beer I've ever had!
