Trewithen Dairy is a family business and leading supplier of great tasting dairy products to the South West and beyond. Proud ... to be part of the thriving Cornish dairy sector, we buy every drop of milk that is produced by our local herds all within 25 miles of our Dairy here in the Glynn Valley. 100% Cornish from our local herds, our award winning products are full of natural goodness. Our hero products are bottled fresh milk and Cornish clotted cream, as well as butter churned with Cornish cream and yoghurt made with Cornish milk. We operate a chilled delivery fleet servicing independent retailers and food service customers throughout the South West, as well as working with a network of wholesale partners to service further afield. You will also find our products on the shelves of many national retailers, including Tesco, Morrisons, Asda, Waitrose, Costco, Coop, Spar. Or online with Ocado and Milk & More. We also supply in bulk formats to food manufacturers, who benefit from provenance claims on their ingredients declaration. read more
