Thought I would add this as there are now three German Kraft brewpubs listed on here and it may help the admins.
There was some debate about whether Mayfair were really brewing but the equipment is in the crypt:
“…the underground crypt bar opposite our 250l micro brewery, where we brew speciality beers.” For context, they also now have a venue in Brixton and that does not mention anything about brewing. (Also gone international and now have a brewpub in Vienna).
The annoying thing is that the pumpclips design is the same whichever of the brewpubs you go to. However if someone adds a new beer you can see which locations it’s brewed at:
Our Beer • Crafted in the heart of London (germankraft.com)
Some are available at all three or a couple. However when I went to the Dalston venue I had Peter and that only specifies Dalton on the list.
Have to be quick though because, whilst there is a beer archive, they delete the venue/s and state ‘Drank Dry!’ once the beer’s gone.
(If they are brewed by one or more venue they seen to always be brewed at Elephant & Castle so perhaps default to that one?)
Edit: just spotted the following!
