Where can the real bargains be discovered? Mostly in the south, including the deep south of France. Under the name Vin de Pays d Oc, there are varietal wines that can sometimes turn out sensational. For example, this Sauvignon blanc from Astruc, which can stand up to even a good Sancerre with its mineral-grassy fruit. Wonderfully fine fruity wine - and at the price an unbeatable bargain.
