Once a sister property to Thomas Barton's Châteaux Langoa and Léoville Barton, 18th-century Château Le Boscq was purchased by Maison Dourthe in 1995. It then went through a complete renovation and a big step up in the quality of its wine. Its 18 hectares of vineyard, unusually in one single block, are planted on gravel and clay soils in the northern part of Saint-Estèphe.

Clay provides a cooler soil which favours Merlot, hence a higher than normal proportion of Merlot is planted – just over half, with 35% Cabernet Sauvignon, the usual hero of the Left Bank, plus Petit Verdot and Cabernet Franc. A year's ageing in nearly half new oak barrels adds to the gravity and longevity of this firm claret. Open early and decant or cellar a while.

Founded 200 years ago, Château Pédesclaux is a magnificent estate, both in terms of wine and architecture. It combines the beauty of the 19th century with the modernity and technological advances of the 21st.

The additional work was undertaken by architect Jean-Michel Wilmotte, whose aim was to place “production at the heart of the estate within a high-performance building that is entirely fit for purpose and makes a harmonious whole with both the château and its surroundings”. It's quite something to behold.

Since the Lorenzetti family took ownership they've converted to organic. Their top wine is a rich, Cabernet-based claret, supported by Merlot, and finely expresses its gravel terroir. Still a young wine – best to cellar or open early.

Gascony used to be a one-trick pony, making the fine spirit of Armagnac. The market for that dropped dramatically 30 years ago, and growers had to search for another use for their grapes. They discovered that their Atlantic influenced climate was ideal for producing crisp, fruity whites. Good value too. Domaine de Mouchan, on the edge of the Landes de Gascony forest, has been the pride and joy of the Braisant family since 1949.

They have 58 hectares of vines growing local heroes Colombard, Ugni Blanc, Gros Manseng, even the red grape Tannat, plus Sauvignon and Chardonnay. They still produce eau de vie Armagnac, but also bright crisp, fruit driven whites like this gem. Chill down, it makes a delightful apéritif or partner to lighter dishes.

Provence is France’s premier rosé region and Domaine de Paris is one of its most stylish and elegant. A previous vintage even gained mention in the prestigious US journal Wine Spectator: “Very good – a wine with special qualities. Dry and refined, with dried berry and cherry flavors and plenty of minerally notes.” The estate has been owned since 1900 by three generations of the Brun family.

50 year old Syrah and Grenache vines produce fruit of superb concentration and impeccable purity. There’s a tantalising steeliness to the structure, a flinty backbone coupled with wild strawberries and a lovely savoury note. Fine Provence rosé is not just for summer! The locals enjoy it all year round, on its own or with seafood, chicken or ratatouille.

Our scout and buyer for the Languedoc-Roussillon is Mark Hoddy. He's always searching the region's vineyards, to check out the vintage and the finest parcels of grapes. This is an ace find Mark discovered first in 2019 via an old friend in Corbières. Close by is Domaine La Lirande, a small estate founded in 1912 by the grandfather, François, in the tiny village of Coulobres. Every year, the Syrah from the domaine's 8 hectares of 40-year-old vines stands out for quality. Just taste the richness of this seductive red. Ripe black fruit, velvety, with smoky liquorice and wild herb notes, it's young, so best with hearty dishes like pasta bake or at a barbecue.
