Terry Kirby selects the best bottles to buy

The first weekend of spring is time to savour some refreshing Southern Hemisphere whites…

Sunday lunch

Delta Sauvignon Blanc Marlborough 2012

This zesty mix of grassy acidity and tropical fruits, with a shot of citric grapefruit and lime, will refresh the palate and invigorate the soul. Shellfish or a prime white fish such as brill are ideal. £11.65, etonvintners.com; £11.95, slurp.co.uk (minimum order: six bottles)

Midweek meal

Valcheta Torrontes 2013

The enticingly floral aromas of an Argentine Torrontes from the Mendoza valley can, paradoxically, remind us of the joys of our spring hedgerows, bursting with wild flowers. Despite the floral nose, this is bone-dry, and its light, peachy flavours marry well with all types of fish, particularly if cooked with Asian spices. £8.65, jascots.co.uk

Bargain basement

Cono Sur Bicicleta Viognier 2012

This Chilean Viognier is a gorgeous rendition of a grape that can command ridiculous prices as Condrieu in France. Characteristic floral aromas and flavours of honey, apricots and hint of smoke, but wonderfully fresh and clean on the palate. £7.49, morrisonscellar.com; £7.50, Asda
