Discount supermarket chain Aldi has reported strong Christmas trading, driven by growth both in-store and online with its wine and special-buys offer.

For the four weeks to December 24, Aldi sales grew 10.6% year on year, while online wine and special-buy sales soared 75% year on year. 

The retailer said “shoppers’ desire to treat themselves after a difficult year” saw its premium Specially Selected range outperform year on year. It also saw strong demand for its beers, wine and spirits – selling 4.5 million bottles of champagne, sparkling wine and prosecco last month.

Aldi reported that “thousands” of customers ordered their groceries online through its click-and-collect service and on-demand delivery partnership with Deliveroo.

Aldi UK chief executive Giles Hurley said: “We had a record Christmas with unprecedented demand for our award-winning products as customers pushed the boat out more than ever before.

“We are expecting significant sales growth this year as we open new stores and bring Aldi to more locations across the UK. With the vast majority of our grocery products now coming from British suppliers, our growth will lead to additional jobs and investment in our UK supply chain.”

The retailer has committed to spending an additional £3.5bn a year with British suppliers by 2025 as part of its expansion plans. It is also targeting operating 1,200 UK stores by 2025.
