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.

For piercing, ultra-fresh Sauvignon, Elqui Valley is a top spot. It’s an extraordinary region in the north of Chile next to the Atacama desert. 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. Enjoy on its own or partner with spicy Asian dishes or fish.

Since 1980, Jacky Gilson has been a grower and winemaker in the tiny, forgotten Burgundy region of Saint-Bris. In fact, the appellation was only created in 2003. It lies just 10 miles west of Chablis and is the only one permitted to use Sauvignon Blanc in its wines. Jacky himself grows both Sauvignon and Aligoté in his 40 hectares of vines, specialising in tantalisingly fresh, pure, crisp whites.

Hard work in the vineyard and minimal intervention in the cellar makes for very pure fruit whites, big on aromatics and with a core of freshness. Aged on its lees for six months, it has roundness too. Chill and enjoy as an apéritif, with garlicky snails or grilled fish. And from such an exceptional vintage, there is no rush with this wine.
