Located on the site of the former Coulon dairy, Claude Thiery opened the brewery of organic craft beers in 1999. In 2014 the brewery was taken over by the current owners.

Sébastien Courtin has long had a passion for beer. When the Brasserie du Marais, in Coulon, launched a call for projects to take over the brewery, he seized the opportunity to turn his passion into a profession, after obtaining a University Diploma in Brewery Operator at the University of La Rochelle.

In 2014, the first brews were made with the help of the University of La Rochelle. Today, the Brasserie du Marais offers 9 beers including a blonde, an amber, a triple, an IPA, a white and even a lemonade for children. It works with the Bellefois brewery in Neuville-de-Poitou, for barley which is then malted in the Indre in Issoudun, pending the creation of a sector for Poitou-Charentes. The beer is neither filtered nor pasteurized.
