But our top insider secret? There's another 'M' out there making truly brilliant Sauvignon – Moldova.

Like Marlborough, Codru in Moldova has a long, slow ripening season.

It’s cold winds keep the grapes healthy and mean the vineyards can easily be grown organically.

Albastrele is made with handpicked grapes from the Tvarditsa Estate at an award-winning cellar well equipped for producing bright, modern whites.

Made from carefully selected handpicked grapes, winemaker Marian Haraba has crafted a truly impressive white wine.

Bursting with vibrant gooseberry and citrus aromas, Albastrele makes an elegant apéritif or a delicious match for grilled fish or smoked salmon.

Thanks to snowmelt from the Andes and the wonders of irrigation, green and flourishing vineyards stand out in contrast to their lunar-like surroundings.

Alta Tierra is from Viña Falernia, owned by cousins Aldo Olivier and Giorgio Flessati.

They have 135 hectares of beautifully manicured vineyards and an ultra modern cellar. In 2005 their first vintage won a Trophy and put Elqui on the map.

This dazzling Sauvignon Blanc displays classic varietal character of elderflower and freshly mown grass with ripe melon and citrus fruit.

Serve as an aperitif or partner with spicy Asian dishes or fish.

When Hermann Schroeder decided to build a winery in 2001, little did he expect to unearth the fossilised bones of a 75-million-year-old dinosaur, later named Panamericansaurus Schroederi after the family. Aside from dabbling in accidental palaeontology, the Schroeders also make a range of award-winning wines. Their brand ‘Saurus’ paid tribute to the amazing discovery, whereas ‘Bariloche’ is named after a modern treasure of Patagonia.

The quaint town of Bariloche, a hot spot for winter sports, hosts the source of a number of meltwater rivers that feed into the valley where Schroeder’s vineyards lie. Made from handpicked Malbec grapes with a touch of oak, its bright cherry fruits come forth with a swirl of the glass. Ideal with grilled meats.

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.

Since he took over the family estate in 1990, he has also acquired sites in Languedoc, Roussillon, Provence, Alsace – and far afield in Oregon, Australia’s Heathcote and Portugal. Domaine de Bila-Haut is his prize in the Roussillon’s Latour de France.

Its rugged slopes include soils of gneiss, schist, chalk and limestone, lending richness, depth, power and finesse.

This white is made from Grenache Blanc, Grenache Gris and Macabeu, with a little this vintage of Marsanne, Viognier and Roussanne for a more aromatic style.

Pure, unoaked and with white peach fruit, it pairs well with trout or chicken, but is great solo, too.

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.

The Pic Saint-Loup was elevated to AOC status in 2016 in recognition of the region’s consistently outstanding wines. Named after the peak which bears the same name, the waters here are pristine, and the south-facing vineyards embrace the cool breezes of the Mediterranean.

La Closiere is an 80/20 split of the region’s iconic Syrah and Grenache. Small barrels are used for the Syrah (half of them new), while the Grenache is left to its own devices in larger 2,000L foudres. At 15% alcohol level, this is a hefty beast of a red but retains a beautiful elegance thanks to exquisite craftsmanship.

Château Lavabre La Closerie 2018 has been racking up some excellent scores from the world’s top wine critics…

“… a blockbuster bouquet of black fruits, camphor, graphite, ground pepper, and cured meats. With a touch more finesse and focus compared to the appellation release, it's full-bodied and has a beautifully balanced, concentrated, elegant mouthfeel, ripe tannins, and a great finish…”

“Blueberries, blackberries and licorice notes mark the nose, supported by hints of crushed stone and spicy oak. It's full-bodied and ripe but still balanced, with a more streamlined feel than the other Lavabre reds, along with silky tannins and a long, licorice-laden finish.”

“Opulent! Incredibly concentrated… Lots of sweetness but at the same time it isn't sweet. Fig molasses. Coal dust. Graphite. Caraway. Lots of texture on those tannins… Huge power and broad, glossy, muscled shoulders. Nothing understated about this wine."

Once a sister property to Thomas Barton's Châteaux Langoa and Léoville Barton, 18th-century Château Le Boscq was purchased by Maison Dourthe in 1995. It then went through a complete renovation and a big step up in the quality of its wine. Its 18 hectares of vineyard, unusually in one single block, are planted on gravel and clay soils in the northern part of Saint-Estèphe.

Clay provides a cooler soil which favours Merlot, hence a higher than normal proportion of Merlot is planted – just over half, with 35% Cabernet Sauvignon, the usual hero of the Left Bank, plus Petit Verdot and Cabernet Franc. A year's ageing in nearly half new oak barrels adds to the gravity and longevity of this firm claret. Open early and decant or cellar a while.
