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.

When I came over the high pass south into the Agly Valley in the 70s, I was captivated by the ancient vines on steep, terraced hills, topped by high, ruined castles. It was wild 'unknown' territory. That's where bestselling Cabalié, made by the legendary Hervé Sabardeil, is from. Hervé buys grapes for Cabalié from many vineyards, but the best grapes came from two vineyards of 100-year-old vines on schist/granite soils. They are two of France's oldest vineyards, lying on steep, terraced hillsides. When Hervé learned the farmer was retiring, he bought those two vineyards – and thus we have the 'Grand Cru' Origine … the purest essence of Cabalié … made solely from those two vineyards. It's a nearly all dark, spiced Carignan, with a few rows of silky Grenache, Syrah and Mourvèdre, which add to the incredibly rich fruit and luscious texture.

Formerly known as Capbern Gasqueton, this Cru Bourgeois Saint-Estèphe estate has been in the same family for 10 generations. It's the same family that owns 3ème Cru Classé Calon Ségur. It lies in one of the finest parts of the appellation, between Phelan Ségur and Meyney, and every aspect is given Grand Cru care. Hand picking of the 41 hectares of vines, with ageing in top-quality oak, all adds up to the exceptional quality.

This vintage has gathered many top scores from wine critics such as Jeb Dunnuck and James Suckling, who called it "full-bodied with a deep character". Two thirds Cabernet with almost the same in new oak, it has “gorgeous cassis, violets, classy oak, with beautiful tannins” (Jeb Dunnuck). One to cellar for a few years.

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.

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)

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.
