Discover our delicious dairy products

Cornish Cream

Our indulgent, award winning cream is as fresh and as natural as it is unbelievably creamy and rich.

Cornish Milk

Our Cornish milk comes from our own directly contracted farmers, all based within a 25-mile radius of our dairy. We are caretakers of the land; we and our farmers recognise the need to look after the environment for future generations.

Cornish Butter

Our creamy butter is as deliciously rich as it looks. We’re not sure if it’s the luxuriously smooth texture, the buttercup yellow colour, the rich flavour or the fact that it’s churned using Cornish cream that makes it so special.

Cornish Yoghurt

Our indulgent yoghurts are bio live and a source of protein. Thick, rich and creamy with a distinctively luxurious taste, Greek style has never been so simply delicious. Drizzle with honey, top with granola or pair with your favourite fruit.

Our story

Trewithen Dairy was founded and run by the Clarke family, who owned Greymare Farm in the Glynn Valley since 1976, and started crafting dairy products there in March 1994. Still located in the Glynn Valley, we now have over 250 amazing employees and work with over 35 local family farms. Together we craft award winning products like our famous clotted cream and salted butter.
