At the end of the 19th Century, the vast majority of the Cognac vineyard was ravaged by the disease Phylloxera.
B. Léon Croizet refused to let his estate die away.

Instead, he planted experimental vines from America. In order to protect them, he built stone walls around certain small vineyards.

His techniques were adopted by many vineyards owners and this helped to replant the vineyards of Cognac. In recognition of his work, B. Léon Croizet was awarded in 1883 the Légion d’Honneur by the President.
