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, and taste 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.
