Blue Keld B'free Lemon-Lime soft drink

Blue Keld is a prominent British brand of natural mineral water and flavored beverages. The water is sourced from a genuine artesian spring located on the edge of the Yorkshire Wolds in Driffield, East Yorkshire, United Kingdom. The brand's name, 'Keld', is derived from an ancient Viking word for 'water' or 'spring', paying homage to the historical Norse influence in the Yorkshire region.

The company was originally founded in the early 1990s by John Thompson, a local farmer who discovered the pure, chalk-filtered water beneath his land. In 2003, the business was acquired by the J Marr Limited group (also known as the Marr Group), a major industrial entity based in Hull. Today, Blue Keld is recognized for its distinctive blue bottles and its range of 'B'free' products, which provide flavored hydration with zero sugar and zero calories, catering to health-conscious consumers across the UK and international markets.
