Domain Diochon is a 12-acre estate in the Moulin-a-Vent appellation in Beaujolais. It was founded in 1935 and run by the Diochon family for two generations. In 2007 Thomas Patenotre was brought in to take over the estate when Bernard Diochon retired. The estate makes just one wine, a Gamay Vieilles Vignes Cru from vines at least 50 years old.
