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 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.

Michel Chapoutier is renowned for his brilliant Rhône wines, but this region alone couldn’t contain his brilliance.

Southern Burgundy’s Mâconnais has long been known for being a hotspot for good value but in the last decade its winemakers have proved that this goes hand in hand with remarkable quality too. They may not be able to put ‘Grand Cru’ on the label, but some of the bottles certainly warrant it. The Greuzards have been crafting superb wines at their Greffière estate for four generations now.

In fact there is evidence the property was making wine from 1585. Their top vineyard – La Roche Vineuse – is 12 hectares with vines 30 to 50-years-old. No wonder the fruit is so deliciously concentrated and long. Slow fermentation with lees stirring results in this rich complex style. Serve lightly chilled with white meats, risotto or a creamy fish dish.

So we were delighted when we finally secured access to some nearby white vineyards with incredible fruit that has allowed us to create the prestigious La Clarière Blanc. This dazzling white Bordeaux combines bright, character-filled Sauvignon Blanc and richer, creamier Sauvignon Gris to create an extraordinarily sensuous wine. It has enjoyed all the same lavish, no-expense-spared treatment in the winery usually accorded to the red, and the result is a citrussy, complex, textured wine that is absolutely irresistible. Oak fermented, lees stirred, and then aged in partnew oak barrels, the richness and complexity is reminiscent of the grand wines of Pessac Léognan. Smooth, rich, long and lavish … it's simply magnificent – a very worthy partner to the red. It's a truly fine dining partner that really shines when served with luxury cuisine.
