For years, Jenlain organized a beer fair. The idea having been taken up by Curgies, a neighboring village, the municipality and the AJT (Association Jenlinoise de Tourisme) have preferred to abandon this festival in favor of the Christmas Markets. Curgies no longer organizing this fair, the AJT was able to relaunch its idea of a beer festival by relying on a Brotherhood.

A ceremony therefore took place at the village hall on September 10, 2000 to formalize his birth. This was the first Chapter. In accordance with traditional protocol, Mr. Philippe WATTIER, vice president of the AJT was enthroned by two other brotherhoods. The Guilde des Eswards Cervoisiers and the Confrérie Cervoise Saint Médard volunteered to play the role of godfathers. So Mr. WATTIER was appointed Grand Master and was in turn able to induct 5 other dignitary members, themselves having sponsored 6 plenary members.

The whole village mobilized to set up the Brotherhood: the costumes were made by Madame Marie-Christine GRAVEZ, the only woman of the Brotherhood. The Jenlin association of Lacemakers was responsible for the production of the standard bearer, representing a devil armed with a pitchfork. The latter and Jenlain's crest were reproduced by a painter, also from the village. The Lutrin and the Tinet are the work of cabinetmakers from the region. The Fourquets as well as the medals were made by local craft companies or those nearby.
