The Yeo Valley dairy brand was founded in 1974 on a Somerset farm by entrepreneurial West Country farmer Roger Mead and his wife Mary. Now run by son Tim, from the outset the products have centred on being organic and passing the ‘yummy’ test.The brand flourished by seizing the opportunities offered by the boom in organic food buying and enjoyed over a 60% share of the organic yoghurt market in 2000. Nine years later it was the country’s most successful organic dairy company.
