About Castle Dairies
Castle Dairies is a family-run Welsh butter producer based in Caerphilly with nearly 60 years of butter-making expertise. Originally established as a milk bottling dairy and Caerphilly cheese maker by Lord Macpherson of Drumochter, the company was purchased by John Emyr Lloyd in 1986, who has dedicated over 40 years to mastering the art of churning cream into premium Welsh butter. The Castle Dairies philosophy centres on quality ingredients and traditional craftsmanship. Every product uses 100% British cream and 100% natural ingredients sourced from the UK, earning the brand multiple Great Taste Awards for exceptional quality. Their partnership with Halen Môn Sea Salt, the renowned Welsh artisan salt producer, began in 2018, bringing together two family businesses committed to authentic Welsh food traditions. Investment exceeding £1 million in recent years has expanded production capabilities, including state-of-the-art Cold Mix spreads technology—a speciality process that only a handful of UK dairies possess. This positions Castle Dairies as a leader in both traditional churned butter and modern spreadable formats. The company now employs over 65 people at their Caerphilly facility, serving both retail and contract butter packing markets. Castle Dairies has achieved remarkable growth, ranking number 23 in The Grocer's 2021 list of fastest-growing food and beverage brands with a 23% two-year compound growth rate. UK shoppers can find Castle Dairies Welsh butter at major supermarkets including Tesco, Sainsbury's, Waitrose, Morrisons, and Ocado, bringing authentic Welsh dairy excellence to breakfast tables nationwide.
