Abigale seems to have ceased production.
I thought there was one more – in Medway – but it’s resisting my googlefu (unless it’s Brupart, Cuxton, Rochester). I’ve read about so many in the county recently I’m forgetting what’s current and what’s gone. There’s Pig and Porter, but that’s Sussex, still to be listed.
Ah, I was right: Kettledrum, Rochester, with no web presence I can yet spot. There is talk of the Phoenix, Canterbury, setting up brewing.
