Malborough Sauvignon Blanc is the most profitable wine in the world, reveals Tim Atkin MW. He adds "it rarely sells for less than 6 and often costs considerably more". What is most surprising about this, he says, is that "if you'd visited the region in the early seventies, you'd have seen enough sheep to set up a knitwear empire". The average bottle price given the high demand is 6.26, which is "the envy of every other wine-producing country". So down to business then and Atkin suggests the "fabulous" 2007 Malborough Blind River Sauvignon Blanc (Oddbins, 10.99) and the "richer, more perfumed" 2007 Fern Bay Sauvignon Blanc (Tesco, 4.99).
