Situated on one of the highest hills in Sauternes is the second growth property Château Lamothe-Guignard, named after the Guignard family who bought it in 1981, and who have owned it ever since.
It had been part of Château Lamothe until the early 20th century, at which point the property split in two, with Lamothe-Guignard taking the majority of the vineyards. These now total 32 hectares, 18 of which come under its second growth status, and which are planted with 90% semillon, 5% sauvignon blanc and 5% muscadelle.
The vineyards are planted in two separate sections: some are on plateaus of gravel soils, whereas the rest are on the chalky-gravel slopes of the Ciron Valley, facing north and north-west. The Ciron river moderates the climate and provides the humidity needed to cause the famous noble rot - or botrytis cinerea - used for sweet wine production here, which shrinks the grapes and concentrates the sugars. At harvest time, there are several successive pickings here to ensure that grapes are only selected at the optimum stage of the rot.
The grapes are then transferred to the estate's winery, which Jacques and Philippe Guignard fully renovated in 1990, introducing the stainless-steel tanks which are now used for fermentation. The wines then age in oak barriques.
