The festival - launched in 2014 to coincide with the London Wine Fair – offered self-guided wine tours designed to encourage consumers to discover new grapes, blends and vintages in some of London’s best bars and restaurants.
More than 100 venues served tasting flights of wine to wristband wearers for £5 per flight, and early estimations show that over 10,000 flights were served.
Emma Murphy, London Wine Week festival director, said: “It was a roaring success. We are overwhelmed by the response to this year’s festival, with more than double the number of wristband wearers getting out in London's bars to try new wines and expand their knowledge.
"It shows what a growing thirst there is for approachable and innovative wine events in the capital.”
