Let’s go back in time! To the 1st century AD and vineyards planted to serve the ruling elite at the thriving Roman port of Troia. Here, on Portugal’s windswept Atlantic coast, the only grape that thrives in the dry, sandy soils and super-hot sun is local star Castelão. This small, dark-skinned grape boasts fathomless depths of flavour – if you know how to unlock it. Back to today and enter Gold-medal maestro Jaime Quendera at Portugal’s most awarded winery, Casa Ermelinda Freitas. Only made in the best years, this Black Red flies of our shelves as soon as it's in stock. So our advice is: if you see it, buy it! Rippling with ripe plums, black fruits and laced with chocolate, with a spicy oak finish. At 14.5% it’s got power, so sip slowly.

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.

Martinborough may be less high profile than other Kiwi wine regions (it's only small) but the quality of its cool climate wines is second to none. It lies in the southern corner of North Island and is renowned for Pinot Noir. A government report in 1979 had highlighted that the conditions of the region were remarkably similar to Burgundy – free-draining gravel soils, with moderate temperatures and rainfall. Jeremy Corban and Katherine Jacobs founded their beautiful family estate in 2005, after a wine stint in France.

They chose a site in Martinborough's Te Muna valley and planted Pinot Noir. This is their gloriously fragrant, expressive flagship wine. Aged in new oak, it has a lovely balance of ripe fruit, spice and savouriness. Open early.

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.

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)

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.

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.
