Georges Duboeuf Moulin-a-Vent Beaujolais

In the 19th Century, Romanèche-Thorins had four manganese mines – among the biggest in France – from which the famous “glazier’s soap” was extracted and used to whiten glass. The mines used for growing vines were closed in 1919. But the manganese remained, which gives the wines their particular Moulin-à-Vent cachet.
