Fourpure Brewing Co

Jezza says

This one is not quite under a railway arch but it's close to South Bermondsey station (trains from London Bridge, which take just 5 minutes). Slightly tricky to find despite its proximity to the station: from South Bermondsey station, go onto Rotherhithe New Road and turn right. Take a right into the industrial estate at its main entrance c.100 metres before the railway bridge; follow the road round to the left inside the estate and go under the railway; you'll eventually see Fourpure ahead of you at No 22. The tap room set up has changed and been moved around a few times over the years, and the July 2019 incarnation sees the biggest version yet: it's very smart and spacious, with a total of 43 taps, though this is basically two banks of the same beers duplicated, so an overall total of around 22 different beers at any given time.
