Located near Richmond railway station and Kew Gardens, the shop covers two floors and is double the size of the original Chipstead store. A tasting room on the lower floor will be available for private functions and wine tasting events.
Established in 2004, Essentially Wine specialises in estate-bottled fine wine from small and unusual vineyards. It also sells wine accessories, glasses, and cellars.
The expansion follows the launch of essentiallywine.com last June.
Founding director Stephen Forward said: “This project has taken a year to plan and execute, and I am delighted with the results. The support we’ve received from the local community since opening has been overwhelming.
"I am passionate about supporting the smaller wine producer and vineyard and hope to inspire people to buy wine in a more bespoke, informative and personal environment.”
