Roger and Mary Mead moved to Holt Farms in 1961. It forms the centre of Yeo Valley's organic farming business, Holt Farms. Today, Yeo Valley is the largest organic brand in the UK and number 73 in The grocer's 2014 Top 100 Food Brands. Holt Farms produce three million litres of milk a year. Triodos Bank has funded the installation of a 500kW solar array and the establishment of an educational link between the conference centre, the farm and the Yeo Valley Organic Garden to demonstrate renewable energy projects, good agricultural, environmental practices and a sustainable and profitable farming system.
