Château Bastor-Lamontagne is a first-class estate located in the commune of Preignac in Sauternes. Bastor Lamontagne has a long and colourful history - since 1936 it has been owned by Crédit Foncier. Its 50 hectares of vineyards border those of Château Suduiraut and are planted with 80% Sémillon and 20% Sauvignon Blanc.

Bastor Lamontagne's wine is fermented in a combination of stainless steel and oak barrels and is then matured in small oak barriques (25% new) for 15 months. Typically it is medium to full-bodied and packed with lusciously sweet, honeyed fruit. Bastor Lamontagne can be drunk young, though develops further complexity with 5-10 years of cellaring.
