Our wines

Classified in 2020 as a Cru Bourgeois Exceptionnel, Château Le Boscq is a prestigious, elegant Saint-Estèphe wine, harmoniously allying the power of Cabernet Sauvignon and Petit Verdot with the delicacy of Merlot.

Refined and well-balanced, the wine shows great potential and will improve with ageing.


Château Le Boscq is blessed with one of the finest aspects in Saint-Estèphe. The exceptional terroir, reaching 18m at the highest point, and gravel and clay outcrop, run alongside the Gironde, Europe’s largest estuary. Like the finest classic Medoc estates, Le Boscq lies on the front line where the microclimate often proves a godsend.

No expense is spared in revealing the exceptional quality of this premium terroir. Careful mapping of the vineyards has brought in-depth knowledge of each parcel and micro-parcel. The grape variety-terroir mix has therefore been carefully planned. The gravel outcrop promotes optimum ripeness in the late-ripening Cabernet Sauvignon and Petit Verdot, while the slopes, with their cooler soils, are ideally suited to Merlot.

The estuary, which acts as a natural regulator, mitigates the effects of cold winters and very hot summers. The vineyard therefore manages to escape devastating frosts in 2017 and 1991, and also the 2003 heatwave.

Winemaking and ageing

Chateau Le Boscq - Dourthe

The grapes are received in a gravity-flow winery. The tank room is equipped with a system of optical sorting backed by densimetric sorting, to ensure a very precise selection of grapes, which are then gently transported by conveyor belt. The wines are aged in barriques, separated into batches until the blending stage, in two partly underground cellars.

Interestingly, not a single pump is used to receive the grapes in the winery in order to protect the quality of the grapes and keep the berries whole. Vinification takes place in small-capacity stainless-steel tanks. This way, small parcels of identical grapes can be vinified together, continuing the precision-led approach initiated in the vineyard.

The winery is equipped with optical and densimetric sorting for greater precision in sorting the grapes.
