Does anyone have info on Brewdog Tokyo.

It is to be featured at a beer festival at Pub Du Vin in Birmingham 1 - 4 April but no ABV is given. Flyer says it has never been offered in cask before.

Bottled variety is 18% ABV. Beer Mad has a Tokyo listed as 12% ABV.

I may be wrong, but I am sure it was on at Tamworth beer festival called Tokyo Black possibly 2008.

Are there 2 different Tokyo's out there?
