Established in 1987, the Pessac-Léognan appellation is relatively young compared to other Bordeaux appellations. However, its history is deeply rooted in the ancient vineyards of the Graves region, which have been producing wine since Roman times. The Pessac-Léognan appellation lies just south of the city of Bordeaux, and its terroir is characterised by gravelly soils, providing excellent drainage and heat retention, which are essential for producing the region's highly-regarded wines.

The production methods used in Pessac-Léognan reflect the region's dedication to quality, innovation, and tradition. Winemakers here employ a combination of traditional and modern techniques, including hand harvesting, meticulous grape selection, and temperature-controlled fermentation. The use of oak barrels for ageing is common, imparting complexity and elegance to the wines. The region is best known for its red wines, which are typically a blend of Cabernet Sauvignon, Merlot, and Cabernet Franc, with smaller amounts of Petit Verdot and Malbec. However, Pessac-Léognan also produces exceptional white wines, made primarily from Sauvignon Blanc and Sémillon grapes, often with a touch of Muscadelle.

One of the most iconic wine producers in Pessac-Léognan is Château Haut-Brion, a First Growth estate with a history dating back to the 16th century. Haut-Brion is known for its robust, full-bodied red wines, which exude elegance and complexity with layers of dark fruit, graphite, and earthy undertones. The estate is also renowned for its dry white wines, crafted from a blend of Sauvignon Blanc and Sémillon, displaying notes of citrus, honeysuckle, and mineral complexity.

Another celebrated producer in the Pessac-Léognan appellation is Château La Mission Haut-Brion, a historic estate dating back to the 17th century. La Mission Haut-Brion produces exceptional red wines with a reputation for intensity, depth, and longevity. These wines are characterised by their opulent fruit flavours, integrated tannins, and notes of tobacco, leather, and truffle.

Domaine de Chevalier is a highly-regarded producer of both red and white wines in Pessac-Léognan. Established in the 19th century, Domaine de Chevalier is committed to sustainable viticulture practices and a deep respect for its terroir. The estate's red wines are known for their elegance and finesse, with a focus on Cabernet Sauvignon and Merlot, while its white wines showcase the complex interplay between Sauvignon Blanc and Sémillon, offering notes of citrus, pear, and subtle oak influence.

Smith Haut Lafitte is dedicated to organic and biodynamic farming practices and is known for its refined red wines, which display a harmonious balance of fruit, tannins, and acidity, with notes of blackcurrant, cedar, and spice. The estate's white wines are equally impressive, offering a vibrant expression of Sauvignon Blanc, Sémillon, and Sauvignon Gris, with hints of citrus, white flowers, and minerality.
