Rescued from dereliction in 1954 by Georges Brunet, La Lagune was subsequently sold to the Ducellier family of Champagne Ayala. In 2000, both La Lagune and Champagne Ayala were sold to the Frey family.
Ayala was then sold to the House of Bollinger, and the Frey family acquired Maison Jaboulet in the Rhone. The Freys are also a substantial but not majority shareholders of Billecart-Salmon, the producer in Mareuil-sur-Aÿ.
