Castillon's limestone plateau is the "seamless" extension of the fabled Saint-Émilion (Oz Clarke), and these days any vineyard in the area that comes up for sale is snapped up by big Bordeaux names. They've finally latched on to the fact that little Castillon produces wines just as good as its grand neighbour! We were very lucky to get Colombe when we did, and we are excited to share its majestic wines with you. Like La Clarière, it's a silky Merlot-rich blend, and aged only briefly in oak, so it's fruitrich and supple and drinking beautifully now. It's a regular Gold-medal winner (11 Golds in the last five vintages) and is a must for any fine Bordeaux fan.

Its vineyards are nearly all planted to Merlot, with a small amount of Cabernet Franc, and tended with meticulous care. As you can see from critics' scores, it is an admired claret and one that ages very well too. Matured in French oak (50% new), it has structure and length, but above all an appealing depth of luscious fruit and spice – like Christmas in a glass! It’s a luxurious sipper, ideal with cheese after the Christmas feast. “Spiced plums and cocoa-dusted blueberries ... Succulent" (James Suckling, 94pts)

So we were delighted when we finally secured access to some nearby white vineyards with incredible fruit that has allowed us to create the prestigious La Clarière Blanc. This dazzling white Bordeaux combines bright, character-filled Sauvignon Blanc and richer, creamier Sauvignon Gris to create an extraordinarily sensuous wine. It has enjoyed all the same lavish, no-expense-spared treatment in the winery usually accorded to the red, and the result is a citrussy, complex, textured wine that is absolutely irresistible. Oak fermented, lees stirred, and then aged in partnew oak barrels, the richness and complexity is reminiscent of the grand wines of Pessac Léognan. Smooth, rich, long and lavish … it's simply magnificent – a very worthy partner to the red. It's a truly fine dining partner that really shines when served with luxury cuisine.

An exciting, pure and complex dry white that’s reshaping Sauternes’s winemaking history. It's a daring pairing of Grand Cru Classé winemaking skills and the fine terroirs of Sauternes, home to France’s finest sweet wines. Owner, Olivier Bernard, believed that the region’s amazing panoply of soils could also make top quality dry Sémillon. In 2011, he set out to prove it.

He brought in the team from the Graves' Grand Cru Classé Domaine de Chevalier, to help achieve his vision. Using intense, old-vine Sémillon from three terroirs, and a dash of Sauvignon, this cuvée was aged for six months on its fine lees, with 25% in new oak. Together they add layers of complexity and creamy weighty. A masterpiece of luscious fruit, spice and freshness.

Corbières is one of the best-known regions of southern France, adored for its characterful, robust reds, laced with dark fruit, wild herb and tobacco notes. This is a terrific find from the Terre d'Expression cellar in Fabrezan. It's a cooperative cellar, that works with its growers to gain exceptional quality grapes. All the fruit for Villa Pech Fourcat comes from a single estate in Boutenac, the only village in Corbières which may be named on the label.

Its wines are supreme thanks to very stony soils, hot dry summers and cooling winds. Vines for this red are, on average, 65 years old and very low yielding, which only adds to the power and intensity of this fabulous wine. For drinking now, open a couple of hours beforehand and decant.

This is one of those 'under-the-radar' regions I love to search out, home to the finest quality wines, but not so well-known. As Wine International says, "If it weren't for the [political] line dividing Castillon from Saint-Émilion, its wines would be twice the price. The hills are the same, the soil is the same, the exposure is the same." The estate has won over 150 awards, including the Paris Lauréat Prix d'Excellence – not once, but twice – and Decanter magazine calls it the "leading estate in the Côtes de Castillon". La Clarière is our flagship wine and absolutely no expense is spared. Low yields, careful hand-sorting, months ageing in the finest new French oak, and rigorous tasting ensure only the best parcels become La Clarière. Mostly Merlot, silky, elegant, and supple, with a dash of Cabernet Sauvignon for structure, and slightly portioned Malbec and Cabernet Franc for balance. It's truly magnificent!
