Sainsury’s will close the site, www.sainsburyswine.co.uk, from the end of July, in preparation for the launch of a non-food sales website early next year.
Extra resources will also be given to the main online grocery site, which will continue to include wine and Champagne.
A company spokesperson told OLN the group was unable to break out online wine sales, but added: “It’s a very small proportion of sales. Most people will shop in-store for their wines.”
Sainsburywine.co.uk was launched in 2001 as a site for specialist wines.
