I've just worked at The Liverpool Beer Festival. Liverpool Organic sponsored it. They have done an Imperial Russian Stout at 7.9% and it was bloody lovely.
There are many that have been posted that I enjoy. My favourites would have to be:
Kronenbourg 1664 (my daily)
Hobgoblin
Jennings Snecklifter
Erdinger
Leffe Blonde
Duvel
Innis and Gunn (think it was the whisky aged but recently tried the rum aged and that was good too)
T.T Landlord
Fullers ESB is an absolute favourite
York Brewery Guzzler (glad someone mentioned it)
Can't think of anymore!
Regarding Adnams - a family member works there but I never liked any of them apart from Broadside which was decent, but the rest all have a strange taste to me - must be Marmite beer!
