The Sherry Institute of Spain is to hold its first Sherry Trail in designated London bars from October 14-27.
The Trail is part of The Great Sherry Festival, which runs nationwide and includes more than 30 wine merchant events, as well as discounts and competitions.
To take part in the Sherry Trail, Londoners visit one of the participating bars to collect a loyalty card, and then ask the bar staff to stamp their card for each glass of sherry they drink. Stamps can be collected throughout the two-week period, at any of the sherry bars taking part. Then, when their card is full, consumers hand them in to the bar and they'll be contacted if they're a winner.
Prizes include books on sherry, T-shirts, aprons, bottles of sherry and the main prize - a trip for two to Jerez, Spain.
Graham Hines, UK director of the Sherry Institute of Spain, said: "Visiting a variety of bars in an evening is commonplace in Spain and we wanted to bring a little of that tradition to London's growing number of sherry bars." He continued: "The trail lends itself perfectly to sherry, with so many styles of it to enjoy we think Londoners will love trying a different sherry around the fabulous selection of sherry bars now available to them, salud!"
The Sherry Trail takes place only in the following London venues:
