So many options but heres a few : Samual Smith Old Brewery Bitter, Timothy Taylor Landlord, Black Sheep Bitter, Youngs Double Chocolate, anything from the Pitfield Brewery if you can find it, from the UK. From Belguim try Hoegarten, Rodenbach, Leffe, try lambic beers by Morte Subite, or an Abbey Beer by Orval. etc. From the US try Samual Adams, Brooklyn Lager, Steam. Of course if its hot or even if its not you could have a Heineken, and that would be fine too !
