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.

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.

Finding a parcel of 2010 claret nine years after this 5-Star vintage was a coup for our Buyer Jean-Marc Sauboua. Critic Michael Schuster described the wines of 2010 on release as “massively elegant, fresher, firmer, more tannic”, Suckling praised them for being “very precise, focused and fresh to taste”, “dangerously good” said Jancis Robinson MW.

Médoc wines that year proved particularly good value too. The 40 hectare estate Château Carcanieux has very gravelly soils, hence its original name Carcanieux Les Graves. This encourages superb concentration and ripeness in the wines. Cabernet with Merlot, and aged in barrel, this silky claret has a fine balance of fruit and maturity, with spice from the oak. Decant and serve with steak au poivre.

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!

Lying close to Margaux's Châteaux Giscours and du Tertre, Château Cazauviel remains surprisingly under the radar. It was inherited by Régis Bernaleau from his father in 1978 and today remains in family hands. It is situated on the prized gravel soils of the Arsac plateau, which lends both an intensity and a finesse to the wine. This pretty claret is from a vintage struck by early April frosts – the most devastating for many years.

It reduced yields, but as Decanter wrote, "there are some excellent wines." Most, like Cazauviel 2017, are not long keepers, but makes delightful drinking now. Ideally open a couple of hours before serving and decant. It'll make a delicious glass with roast chicken with morels or a mushroom croustade.
