UK Craft beers:
Brewdog - Tactical Nuclear Penguin (32% ABV
There are stronger ones, but TNP tastes best IMO.
Brewdoh- Sink the Bismark (41%ABV!!!) is a good chaser! haha
Brewdog -Abstrakt (any of them), Tokyo
Kernel Brewery - IPA Citra
Based in the UK, but often can get my hands on some of the good American craft beers:
Dogfish head 90 Minute comes to mind, Boulevard - The Sixth Glass and Boulevard - Dark Truth. All fantastic! There are thousands more really, loving the craft beer revolution
Delirium Tremens (a good gateway beer
Bush - Skaldis
