About Trewithen

Trewithen Dairy grew from generations of dairy farming, and now we supply and produce the highest quality Cornish produce by working closely with local farmers to ensure their future for generations to come.

We hold a passion for natural and nourishing fresh dairy products with that distinctive Cornish quality. We've learnt from a history of hands-on experience that such produce can be achieved only from happy, healthy cows fed on a nutritious diet of Cornish grass and living a stress free, comfortable life.

Our aim is to offer a professional production and distribution service, without losing the quality and integrity only a company who work directly with the local farmers and valued customers can achieve, selling to local shops, caterers and food manufacturers.

We offer a range of fresh dairy produce, specialising in hearty Cornish milk, pasteurised and bottled fresh on site, and smooth Cornish clotted cream, made using traditional methods to achieve the iconic golden crust and nutty flavour of a quintessential Cornish delicacy.

The Clarke family have been at Greymare Farm since 1977, start with just one employee and expanding cow numbers from 70 to 300. They started processing in 1994 and the latest investments are in bottled milk, with soft cheese available soon. The dairy's existing products also include Cornish clotted and liquid creams, butter, yoghurt and crème fraiche.
