The four-day event, which is split into six sessions, is a “celebration” of great beer featuring 50 breweries from across the globe.

Breweries will each bring 12 kegs to the event and showcase two each session. Those that have already signed up include Weird Beard, Evil Twin, Magic Rock, Prairie Artisan Ales and Thornbridge.

The carnival takes place at The Vaults underneath Waterloo Station and each five-hour session will set you back £50.

For this, you get a limited edition glass, brochure and, importantly, unlimited 90ml samples throughout the session.
