Run by Enotria and BigHospitality, the competition was designed to generate some buzz around the wine category after research showed that the presentation of wine has a huge influence on how much diners spend on it.
The winning entry was of a sign (pictured) drawn by The Don's assistant manager Baptiste Bernard to advertise an event for the restaurant's wine club.
Entries were judged by a team at Enotria and the restaurant and commercial catering design company Catering Design Group before they chose their winner.
"The judges felt it presented wine in a really captivating and creative way, and proves that a strong visual sense doesn't need a huge marketing budget to make it effective," said Enotria communications manager Ben Smith.
Bernard wins a trip for two to Champagne Jacquart this autumn.
