Château La Lagune is a winery in the Haut-Médoc appellation of the Bordeaux region of France. The wine produced here was classified as one of fourteen Troisièmes Crus (Third Growths) in the historic Bordeaux Wine Official Classification of 1855.

History 

Chateau La Lagune has a long history that dates all the way back to the 16th century, under King Henri IV. This was at the same time the Dutch engineers began the modern age for Bordeaux when they started draining the water from the marshes and swamps. The beautiful, classically styled chateau was built in 1715.

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. 

Vineyards

Located in the commune of Ludon, La Lagune has 72 hectares under vine with a grape variety distribution of 60% Cabernet Sauvignon, 20% Merlot, 10% Cabernet Franc, and 10% Petit Verdot.

Wines

To produce the wine of Chateau La Lagune, the wine is fermented in a total of 72 different, temperature controlled, stainless steel vats that vary in size from 22 hectoliters to 200 hectoliters to allow for parcel by parcel vinification. The vats are laid out in a functional and architecturally interesting pattern. Malolactic fermentation takes place in vat. The wine is blended before the aging process begins. This is similar to what takes place at Chateau Haut Brion. The wine is aged in between 50% and 60% new French, oak barrels for 18 months before bottling.

Chateau La Lagune has produced 2 different wines in small quantities blending Syrah from the Northern Rhone Valley with Cabernet Sauvignon with their Bordeaux vineyards. In 2010, they released Evidence, a wine that is made from 50% Cabernet Sauvignon and 50% Syrah coming from vines they own in Crozes-Hermitage.

They also produce one barrel each year, blending Syrah from Jaboulet La Chapelle with Cabernet Sauvignon from La Lagune, calling it Duo. The wine is bottled only in large formats and is sold primarily at auction. Both wines are sold as Vin de France.

There is a second wine, Moulin de La Lagune. The Frey family also produce a third wine, Mademoiselle L from 30 hectares of vines planted in the Haut Medoc appellation. Denis Dubourdieu is the winemaking consultant. On average, Chateau La Lagune produces between 18,000 and 20,000 cases of Bordeaux wine per vintage.
