Favourites include:
Oakham Oblivion
Howerd's town Wren Nest,
Abbeydale black mass,
abbeydale moonshine,
Loads of other Pale ales, generally anything hoppy and fairly strong. I'm often drinking something I've never tried before. If I'm in the sort of shit hole people go to vomit, fight and be deafened in, Guiness is usually the pick of a poor bunch...
