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.

Château de Birot is an elegant, 17th-century property with vineyards perched on a high plateau looking down on the Garonne river and across to famous Sauternes. Until a few years ago, it belonged to the renowned Castéja family. They sold it and the new owners have been working hard, updating the estate. In the cellar, they discovered a forgotten batch of château wine from 2007.

Despite its 17 years’ age, it’s still tasting delicious, complex and long. It’s Merlot dominated from estate vineyards in the superior Premières Côtes, with a little of both Cabernets. After 17 years of maturing in the cellars, it has developed some sediment in bottle. A good sign. Stand the bottle upright for a few hours and carefully decant just before serving.

Renowned French winemaker Gérard Bertrand makes his £40+ a bottle Corbières in craggy Boutenac. Just across a small country road is the village of Fabrezan and its equally amazing vineyards. It's where, in fact, Tony Laithwaite bought his first Corbières shipment back in 1971. Today young couple Amelie and Jean-Baptiste work tirelessly, in evenings and weekends (after their day jobs as consultant winemakers), tending their ancient vines and making their cru quality Corbières.

The vines were planted by J-B's great grandfather, a cellar built by his son, but more recently the grapes were all sold to the local coop. J-B and Amelie took over in 2007 and decided they could make something much better. This fabulous Grand Cru style is the result.

Jean-Marc Diffonty’s flagship red is a rich, opulent, no-holds-barred style of Châteauneuf. It offers layers of dark, smoky, red berry fruit complexity, with a rich seam of spice. From the superb 2021 vintage, it scored 92-94 points from Decanter.
