Sainsbury's Diet Cola

Sainsbury's Diet Cola is a low-calorie, sugar-free soft drink under the private label of the British supermarket giant J Sainsbury plc. The brand was established in the United Kingdom as part of Sainsbury's extensive range of own-brand alternatives to international names.

As a private-label product, it is manufactured within the United Kingdom through a network of bottling partners, often companies like Refresco or Cott, though the specific facility can vary based on the supply chain regional logistics. Ownership remains entirely with J Sainsbury plc, which is one of the 'Big Four' supermarkets in the UK, headquartered in London. The brand reflects the company's long-standing strategy of providing affordable British-made grocery staples to the UK market.
