The Sussex Cellar is the third cellar to open underneath the shop in St James’s.
Demetri Walters MW, sales manager for private wine events, said: “Our new Sussex Cellar affords us much-needed extra capacity in bringing wine education and entertainment to our clients. This latest venue is of a completely novel design that combines the feel of one of our traditional wine cellars with the exciting architecture, convenience and state-of-the-art gadgetry of a purpose-built venue.”
Berry Bros hosts more than 800 events a year.
The new cellar is named after the Duke of Sussex, who was a regular customer in the early 19th century.
