The private-label “Specially Selected” premium range saw demand increase by over 12%, with sales exceeding 5.5 million bottles.
CEO of Aldi UK and Ireland, Giles Hurley, said: “This Christmas proved once again that a great quality Christmas can still be affordable. We delivered a Christmas without compromise, offering customers award-winning British products at unbeatable prices.
“We’re grateful that more people than ever chose Aldi for their Christmas shop and trusted us to deliver both quality and value during what remains a challenging time for many.”
As part of a £325m investment to keep prices low throughout the year, the supermarket promised the lowest possible prices at Christmas.
Hurley added: “As we move into 2026, our focus remains unchanged, keeping prices low and quality high so that every household in Britain can enjoy amazing food all year round.”
