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.

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.

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.

Gascony used to be a one-trick pony, making the fine spirit of Armagnac. The market for that dropped dramatically 30 years ago, and growers had to search for another use for their grapes. They discovered that their Atlantic influenced climate was ideal for producing crisp, fruity whites. Good value too. Domaine de Mouchan, on the edge of the Landes de Gascony forest, has been the pride and joy of the Braisant family since 1949.

They have 58 hectares of vines growing local heroes Colombard, Ugni Blanc, Gros Manseng, even the red grape Tannat, plus Sauvignon and Chardonnay. They still produce eau de vie Armagnac, but also bright crisp, fruit driven whites like this gem. Chill down, it makes a delightful apéritif or partner to lighter dishes.

Pinot Grigio has staged something of a coup in fridge doors and on dining tables in recent years. Gorgeously fruity, well-priced examples like our Il Papavero are rare, however. The wine is from Scipione Giuliani, who searches throughout Italy to find the finest parcels of grapes, usually blending them to get the perfect balance in a wine. For this Pinot Grigio, however, he was so taken with the fruit from the high hills of Sicily, with its idyllic sunshine and sea breezes, there was no need to look elsewhere.

Il Papavero is mouthwatering stuff, a moreish mix of pear and citrus flavours with both ripeness and bracing freshness thanks to the coastal cooled location of the vines. Pure delight on its own or with white meats or risotto.

We're delighted to joined forces with the internationally respected Royal Botanic Gardens, Kew, home to the largest living plant collection on the planet. Together we have produced a small range of wines that champion little-known grape varieties, often on the verge of extinction. Both parties champion biodiversity and work with nature to create beautiful things. In this case, a wine from a small family estate in Sicily.

This refreshing white is pure Carricante, an indigenous grape of the island, in particular of the volcanic slopes of Etna. Bright and zingy, with ripe stone fruits, floral hints and a crisp, mineral finish, this wine is a perfect foil for light, creamy pasta, risotto or seafood.

If you enjoy the freshness of Loire Sauvignon, you must try this great-value rival from the sunny south. It's from Hervé Sabardeil, a very gifted winemaker we've known for many years. His plan was to make the freshest, most aromatic, good-value white he could from whichever vineyards it took. Hence its ‘Vin de France’ classification. For Hervé, wine is an expression of nature's finest – the soil, the sunshine, the grape. La Belle Saison does that very well.

Pure and full of citrus zip, this wine has the freshness you'd expect from a Sauvignon, plus a light tropical fruit note thanks to the warmth of southern France. Delightfully refreshing, this Sauvignon is crisp, fruity and easy, on its own or with light dishes of grilled fish or salads.
