British wine experts were left dumbstruck by a Hawke's Bay winery that went head-to-head with some of the greats in a blind tasting in London.

Craggy Range winemaker Rod Easthope took six 2005 and 2006 blends to the taste-off to compete with six 2005 clarets.

According to The Daily Telegraph’s wine writer, Jonathan Ray, none of the 30 UK wine masters, including Jancis Robinson, sommeliers, Wine Society buffs and wine journalists were told anything else about the dozen vintages they were sampling at the event at NZ House.
