Yes, in a bavarian context "bruennele" refers to an "[small] [old] well" where water for the village (or just the nearby cottages) is fetched. Because of this, its a place where the people inevitably meet, for a chat or, as in this case, just take a rest from days work and enjoy a glass of wine or two at the nearby located inn.
