Terry Kirby selects the best bottles to buy

Sunday lunch

Trapiche Estacion Malbec 2011

The first of three enticing South American wines is a benchmark Malbec from Mendoza in Argentina. A lovely freshness surrounds the smooth, intense flavours of vanilla, blueberries, sweet cherries and a hint of chocolate. Matches a rare steak, but also all roasted red meats. £10.50, winedirect.co.uk; £11.18, thedrinkshop.com

Midweek meal

Casa Silva Viognier Reserva 2013

A really pure expression of Viognier from Chile's Colchagua Valley displays vibrant flavours of apricots, peaches and the characteristic underpinning of spice and honey. Fabulous with linguine and shellfish or scallops with black pudding. £9.89, sandhamswine.co.uk; £9.95, stainton-wines.co.uk

Bargain basement

Pisano Cisplatino Tannat 2014

Full marks to M&S for unearthing this brilliant gem from Uruguay, one of the less well-known wine-producing countries. The Tannat grape here creates lighter and more elegant wines than in its main home in South-west France, delivering gorgeously juicy red fruits and a real depth of flavour. £7 (until 8 June; normally £9), Marks & Spencer
