Opi Sadler has brought us the customer favourite ‘Waxed Bat’, now he presents the ‘Big Bat’. If you didn’t think a wine could get any richer, silkier and packed with luxurious layers of flavour, you were mistaken. But then, Opi is one of Argentina’s most internationally renowned winemakers and he adores the Cabernet Sauvignon grape.

To achieve such an ageworthy perfection, he selected grapes from the finest, high-altitude vineyards in Altamira, Uco Valley, ageing this grand red for 18 months in French oak barrels. This lends a spicy edge to the rich black fruits. Opi states that Argentina makes "undoubtedly the best Cabernet wines in the world". A big statement, but judging by this wine, he may well be right. An elegant, mature steak red.

Take a minute to read the (literally thousands of) 5-star online reviews for Cabalié. This one is typical: “When my time comes to shuffle off this mortal coil, this is the wine I want in that final glass. It is simply, utterly, indescribably fantastic.” Its secret? It’s crafted by a master winemaker, Hervé Sabardeil, following the centuries-old style beloved of Roman centurions, who first made wine there. Raspberry-rich Grenache, with herby Syrah and Carignan, Cabalié has impressive concentration.

That’s due to the maturity of the vines, most well over 50 years old. The tiny berries they produce give Cabalié extraordinarily rich, ripe flavours. Boasting 8 Golds in as many vintages, this much-loved red is warming solo or with hearty dishes.

Cabalié's popularity is down to a rare combination of imposing richness and easy drinking smoothness. Recreating that in white was no easy task. But Cabalié maestro Hervé Sabardeil has done it – years of searching, blending and hard work come to fruition in this, his ultimate expression of a southern French white. The magical grape mix is old-vine Viognier for intense honeysuckle aroma and soft texture, Muscat for dazzling grapey notes, and Colombard to keep it all zesty. And of course the other key ingredients are bright southern French sunshine, which ripens the grapes to perfection, sea breezes to keep them healthy and night harvesting to ensure maximum freshness. Bursting with tropical fruit, Cabalié is perfect with seafood or chicken.

Fronsac's fine Château Dalem perches high on a hill, surrounded by its 14 hectares of sloping vineyards. It's an historic estate, with records dating back to 1610, that stayed in the same family until 1955. Michel Rullier then took it over and today it's run with great success by his descendant, Brigitte Rullier-Loussert. 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 (92 points from James Suckling and 94 from Vertedevin), 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 fruity depth. Perfect with roast meat or wild mushroom risotto.

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)

Until 1997, Château Haut Brisson was an 8-hectare estate in the Vignonet section of Saint Emilion. New owner Peter Kwok was keen to expand its vineyards and the range of terroir, so began to buy up vine parcels to make it up to the 18 hectares it has today. Judging by today's scores and the quality of the wine, Kwok purchased wisely and quality has soared. Today it is under the ownership of Stephane Schinazi and continues its stellar projection, with Michel Rolland as consultant.

All its top grapes go into this wine (they no longer make La Réserve), ageing 30% of it in new French barriques, so as not to overwwhelm the fruit with oak notes. Now certified organic, with the aim of going biodynamic too, the 2020 is a magnificent wine.

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!
