Award-winning Meantime Brewery knows all about beer. It’s even won a gold medal at the World Beer Cup (yes, that exists) for Britain’s first Fairtrade beer. You have the chance to tour the second largest brewery in London, taste five beers, and sample a beer not available anywhere else. You even get to try the raw ingredients that go into a brew, before moving on to the real deal. General admission. Over 18s only. Note: sensible closed shoes are required to go on this tour, no heels or sandals.
