Welcome to Greenbrew

Who are we?

Greenbrew emerged from a joint venture between Jean-Marie Rock and Jean-Didier Buisset.

Jean-Marie ROCK

Brewery engineer

With more than 40 years’ experience behind him, Jean-Marie Rock is making his childhood dream a reality: to set up his own brewery and recreate a beer with a recipe long forgotten by brewers.

Jean-Didier BUISSET


Frequently in contact with breweries during his career, Jean-Didier Buisset’s involvement in the Greenbrew project is also due to a desire to revive family traditions.

Where is Monsieur Rock brewed?

While we await the construction of our Noirefontaine (Bouillon) brewery, we brew Monsieur Rock at the Meantime Brewing Company in Greenwich, London.
