THE latest James Bond film has revived the popularity of the Martini cocktail ingredient dry white vermouth, a retailer said today.

Tesco reported a record 65% rise in sales since Casino Royale hit the big screen.

Demand has been fuelled by fans creating their versions of the famous "shaken not stirred" drink at Bond-themed parties, the retailer said.

Sales of dry white vermouth - which is made by Martini and other brands - usually peak only during the warm summer months, Tesco said.

The chain's spirits buyer Simon Dunn said: "Martini cocktails have made a bit of a comeback in trendy city bars in the last year but this is the first time we have seen a significant rise in demand for bottles of vermouth."

Martini cocktails are made with dry white vermouth plus either gin or vodka with an added green olive.
