Sainsbury's Unsalted British Butter

Sainsbury's Unsalted British Butter is a private-label dairy product sold by J Sainsbury plc, one of the United Kingdom's leading supermarket chains. As indicated by the 'British Butter' branding and the Union Jack imagery on the packaging, the product is sourced and manufactured within the United Kingdom using milk from British farms.

Sainsbury's was founded by John James Sainsbury and his wife Mary Ann in London in 1869. Over the decades, it grew from a small dairy shop into a nationwide retail giant. As a 'by Sainsbury's' product, it is manufactured under contract by British dairy processors to meet the retailer's specific quality standards. The brand remains under the ultimate ownership of J Sainsbury plc, which is a public limited company listed on the London Stock Exchange and headquartered in London.
