Domaine de Villargeau 2010 Côteaux du Giennois
Currently on a deal at Majestic, this was in Decanter a couple of years ago as one of France's top wines for under £10, so now, at £9 each if you buy two, it is a real bargain.
A Sauvignon Blanc from the Loire's Central Vineyard areas, bargain price I suspect because this relatively young appelation (est. 1998) simply doesn't have the reputation that its more prestigious neighbours in Pouilly and Sancerre do - in a similar way to Mentetou-Salon.
Don't expect a kiwi tropical fruit bomb, this is Sauvignon at its most graceful - a glass of elegant, steely finesse.
