The Duchess became president of the United Kingdom Vineyards Association last year.
She enjoyed her first social event with members at Vintnerís Hall in London last night, where OLN joined leading lights from the industry including Oz Clarke and Michael Cox to welcome her.
After trying wines from the likes of Ridgeview and Three Choirs at the English Wine Producers event, she raised a toast to the efforts of UK winegrowers.
ďFrench wines have been going a little bit longer than us but it is a bit like cheeses - we will catch up with them yet,Ē she said.
She also tasted a dessert wine from Denbies Estate in Dorking, Surrey. This land once belonged to her family.
She told guests she has always had a passion for wine because her father, Major Bruce Shand, was in the business.
The Duchess added that some of the functions she attends feel like work, but that this was most certainly a pleasure.
English wine producer Mark Driver, of Rathfinny Estate in East Sussex, said that the climate in the south of England is similar to the Champagne region 20 years ago, and that England is primed to continue producing sparkling wines superior to their French counterparts.
