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.

Reuilly is a real gem for lovers of classic Loire Sauvignon. It offers the dazzling mineral finesse of nearby Sancerre and Pouilly-Fumé, but its wines come at a more affordable price. It's a bit of a rescue story, in fact. In the 1970s, its wines almost disappeared and the little that was produced was only enjoyed locally. Enter Claude Lafond – the saviour of Reuilly. He encouraged the planting of vines, established a shared winemaking facility for all Reuilly producers, and built an impressive, modern winery at Domaine Claude Lafond.

Now run by his daughter, Nathalie, the domaine is farmed organically and continues to go from strength to strength – just like Reuilly itself. La Raie is crisp and elegant. Ideal with goat's cheese.

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.

Winemaker Jean-Marc Sauboua has made wine all over the world. He's won loads of prizes too. But Bordeaux was where he was born and raised and where he's searched out the grapes for this snappy fresh white. He's worked with an award-winning ecological cellar on Bordeaux's Right Bank, Les Vignerons de Tutiac in the Côtes de Bordeaux. This is where you'll find some excellent clarets, but Jean-Marc was out to prove that white grapes could perform just as well. It's pure Sauvignon Blanc, taken from a variety of vineyards in both Côtes de Bourg and Blaye, each parcel contributing a different character to the wine. Bright, lemony and intense, it's an elegant white, as you'd expect from Bordeaux. Chill and serve with panfried white fish or solo.

You couldn’t hope to find Sauvignon of this quality for the price in any of the Loire’s more famous regions, like Sancerre or Pouilly. Blended from the year’s tastiest vats, this wine is as subtle and complex as it is refreshing and zingy. It’s made exclusively for us by our trusted friend Franck Chatelain at Noël Bougrier’s renowned cellar in the Touraine. The original Abbesse was one Louise de Bourbon of the nearby Abbaye de Fontevraud and a major figure in Loire history. This delicious expression of the region’s reigning grape, Sauvignon Blanc, is a fitting tribute to her. With its appealing, crisp, lemony fruit and zippy freshness, it’s delicious on its own any time and goes ever so well with goat’s cheese and lighter fish dishes.
