Held each year at the Earls Court Exhibition Centre, the Great British Beer Festival is the top-drawer event in any British beer enthusiast's diary. Organised by CAMRA (The Campaign for Real Ale), it’s a mind-boggling, discombobulating overload of more beer than it’s possible to imagine. Every non-corporate brewer is here, from the heard of (Fullers, Thwaites) to the local and barely heard of. Beer is central, but there’s food and games too. People are here too. Masses of them. And they’re all happy, friendly and full of good vibes. This event has a great atmosphere.
