Château Marquis de Terme is a historic winery in the Margaux appellation of Bordeaux, classified as a Fourth Growth in the 1855 Bordeaux Wine Official Classification. Its origins trace back to the mid-17th century when it was part of the vast Rauzan estate owned by Pierre de Mesures de Rauzan. Over time, the estate was divided into Chateau Rauzan-Gassies, Chateau Rauzan-Segla, Chateau Desmirail, and Chateau Marquis de Terme. The château officially took its name in 1762 when Ledoulex d’Emplet gave the property as a dowry to Francois de Peguilhan, Marquis de Terme. Its reputation was already established by the 1700s, with American President Thomas Jefferson, a noted Bordeaux connoisseur, declaring it one of the 16 best wines he tasted during his 1787 visit to Bordeaux. Today, the estate remains in the hands of the Seneclauze family, who acquired it in 1935. The 35-hectare vineyard produces approximately 13,000 cases annually. Located in the heart of the Margaux appellation, the property benefits from the moderating effects of the Gironde estuary and the Bay of Biscay, while coastal pine forests shelter the vines from prevailing winds. The vineyard is planted to 55% Cabernet Sauvignon, 35% Merlot, 7% Petit Verdot, and 3% Cabernet Franc on gravelly-clay soils, with a planting density of 10,000 vines per hectare. The Grand Vin is typically blended as 60% Merlot, 35% Cabernet Sauvignon, and 5% Petit Verdot. Vinification includes fermentation and maceration in oak barrels for two months, followed by ageing partly in cement eggs with lees in suspension and 50% in new oak barrels. Since 2012, Château Marquis de Terme has produced a limited cuvée known as Cuvée 9, aged entirely in cement eggs, with only 999 bottles made each year. The estate’s second wine, Termes de Gondats, was formerly called La Mariotte Margaux. With its rich heritage, precise vineyard management, and investment-grade wines, Château Marquis de Terme remains a sought-after property for collectors and fine wine investors.
