Tesco plans to make Localchoice milk more widely available on the back of strong sales figures for its first year.
The supermarket has sold 18 million litres of the milk since it was launched last May, the company reported this week.
Tesco would extend the scheme to further stores this year, confirmed director Lucy Neville-Rolfe, and would also be rolling out new packaging and promotional material.
"We hope to make Localchoice milk the nation's first choice," Neville-Rolfe said.
Localchoice was originally launched in 14 regions, though this has since been extended to 20 regions and 800 stores across England, Scotland and Wales. Until now the line has only been sold in supermarkets and Metros, but it will be rolled out to 200 Express stores over the coming months.
"It gives customers the choice to buy milk from their area and support farmers from their region," Neville-Rolfe added.
