Trewithen Dairy Cornwall

1976

Trewithen Dairy is owned and run by the Clarke family, who have owned Greymare Farm in the Glynn Valley since 1976.

1994

The Clarke family started crafting dairy products there in March 1994.

1994-2000

In the early days the Clarkes had their own herd. Bill and Rachel would bottle the milk once the children were in bed and deliver it early the next morning.

1994-2000

They cooked the clotted cream themselves, in open trays and potted it by hand. Their customers loved all of the Cornish dairy goodness and soon the Clarkes were supplying more and more happy customers.

2001

By 2001 the milk bottling and cream making side of the business had become so successful that a big decision had to be made. To continue dairy farming or switch completely over to processing milk.

2001

It wasn’t an easy decision, but the family sold their herd and moved full time into producing milk, cream and, more recently, butter and yoghurt.

2001-2023

Son Francis now has a key role as Director in the business working alongside a talented and committed management team.

2024

The Clarke family sold the business in June 2024 to the Ehrmann group, an independent 3rd Generation family-owned business, which is one of Germany’s leading dairy companies.

Moving forward it will be very much business as usual. We will continue to be known as Trewithen Dairy and Ehrmann has been very clear that it is committed to harnessing our Cornish provenance and investing in the growth of Trewithen’s Cornish dairy products.
