Supermarket own label wines are on the agenda for Anthony Rose with most chains having "a basic own label and at least a higher quality tier". Own label brands almost faced extinction in the 80s but were saved by the advent of new world wines from the likes of Australia, Chile, Argentina and South Africa. Separating the wheat from the chaff has always been the main challenge, Rose says, but a recent own-brand tasting competition of 427 products in London went some way to providing the answers. The 2007 Sancerre Joseph Mellot (10.49, Waitrose), with its "nettley aromas and flinty mineraliy", won the trophy for best white while the 2006 Shiraz from St Hallett (7.99, Marks & Spencer) took home the plaudits for best red.
