There has been roamers about a Trappist brewery joining the other seven but it seem like it’s not happening. Not yet at least. The roamer was that Abbey Mont des Cats from France was going to start brewing Trappist beer. Mont des Cats have started to brew beer but it will not carry the official Trappits beer logo. There are also roamers that  Abbey Zundert in the Netherlands will brew Trappist beer. So there might be an eighth Trappist brewery soon after all.
