Men may think they know their wine, but it is women who make most of the decisions about what to buy, according to research by French wine exhibition organiser Vinexpo.

UK women bought eight out of 10 bottles drunk at home, reveals the survey of 4,000 women in five countries. They also knew more about wine and were more confident about buying it than their international counterparts, it showed. Six out of 10 said they drank wine at least once a week and just over half said they saw it as a healthier alternative to other alcoholic drinks.

"Women's buying is now driven by price and special occasions," said wine industry consultant Angela Mount. "Wine is now more of a commodity on a woman's shopping list and she decides on a bottle faster, and sticks to familiar variants. Retailers can encourage experimentation by making PoS information more accessible."
