Not long ago I learned from the Green Dragon's Facebook (they posted about it on the 10th) and from sources within the Green Dragon that a new brewery has started in the pub as a separate entity called Buckman Brewing. The brewery is named after the Buckman neighborhood where the Green Dragon resides.
The brewery is being managed by Joe Mattoon and the head brewer is John Couchout who was previously with Rogue as a Master Distiller down in Newport. Buckman Brewing's first beer will be a Chamomile Ale and should be released around July 22nd according to Mattoon.
That's all the information I have at this point. I look forward to trying some of their beers and see what direction they take with new brewery.
