Uhmmm, tough one. I mainly only like lager but I like tonnes of them. Erm, I'll narrow it down to the ones i prefer to buy...

Corona (lime wedge essential)
Chang (a Thai variety that I enjoyed whilst there)
Kronenbourg 1664
Tiger (mainly when in restaurants)

And, for those nights when my liver has been naughty and needs to be punished:

Delerium Nocturnum (not a lager, an ale. The only one I drink. It's got a tonne of flavour. weirdest stuff around).

Hyz.
