The estate owns approximately 80% of the Grand Cru Le Musigny, one of the most hallowed vineyards in Burgundy. Production remains deliberately limited: only the fruit from the oldest vines (40 years and above) goes into the signature cuvée, of which fewer than 1,000 cases are produced per vintage. This low volume, combined with the excellence of the terroir, explains the extreme rarity of these bottles on the market.
