Frequently asked questions

As we look to the future, we want our name to reflect what makes us truly special: our Cornish heritage and joy we bring through food. That’s why Trewithen Dairy has become Cornish Dairy Co. This name is proudly about who we are, tells our story, and is a promise to keep delivering the same exceptional quality to your table.

We can confirm none of our partner farms are involved in the Bovaer feed additive trial. At Cornish Dairy Co, we remain committed to reducing carbon emissions through regenerative farming practices.

The Cornish way to enjoy a cream tea is to break the scone with your hands, before spreading each side with a layer of jam followed by a generous dollop of Cornish clotted cream. The jam prevents the warm scone from melting the cream!

Is it possible to have leftover clotted cream?! We love it stirred through scrambled eggs, spooned into mashed potato and added to ragus to add depth and richness. It’s so versatile for both savoury and sweet dishes – check out our recipes pages for inspiration.

We don’t produce organic milk. We work to a set of high standards and we work with farmers who are exploring regenerative farming tools and techniques.

All our products are made from pasteurised milk, and suitable for pregnant women but always consult with a health professional if you are ever unsure.

Wherever possible our cows graze on pastures and this is independently audited as part of the annual Red Tractor audit.

Although no two Cornish Dairy Co farms are the same, all our farmers share a common set of values and comply with a comprehensive set of standards that ensure high levels of animal health, welfare and husbandry.

We share our farmers’ commitment to continuous improvement in the area of animal health and welfare. As such, we are determined to work with and support them, to ensure that their on-farm practices and performance levels meet the expectations of our customers and ultimately those who consume our products.

Yes, our Cornish milk comes from our own directly contracted farmers, all based within a 25 mile radius of our dairy.

Yes, they are.

We make our clotted cream very carefully, in line with the requirements of its Protected Designation of Origin (PDO) status. We heat our Cornish cream very slowly at a low temperature until we have a generous, golden crust.

Always check the use by date on the pack and consume within three days of opening.

We recommend that you do not freeze our Cornish Clotted Cream as it’s best enjoyed fresh. Freezing affects it’s creamy texture once thawed, leading to it becoming dry and crumbly. Check out our recipes page for inspiration on how to use up any leftovers. Read our blog about ‘can you freeze clotted cream‘ for more information.

Yes, we encourage all our milk bottles and lids to be recycled so they can be made into more milk bottles.

They crush down perfectly just as they are and can be left with your council recycling collection. The lids can be recycled too.

Give them a hot wash in the dishwasher or hot soapy water and ensure there are no visible remnants left after the wash. Leave to dry and you’re ready to take back to refill again.

Wherever possible, our cows are out grazing on Cornish pastures. When the weather doesn’t allow, they’re fed on locally foraged food, so they’re always well looked after, the proper Cornish way.  Some of our farms have salt/mineral licks and scratching brushes for when they’re housed inside, which our cows love!

No. The business is part of the Ehrmann group, an independent 3rd generation family-owned business, which is one of Germany’s leading dairy companies with over 100 years of dairy heritage. Everything is still made locally sourced milk.

Yes. We’re still based at our original site in Lostwithiel, with milk from over 40 Cornish farms within 25 miles, and a 200-strong local team. The Clarke family started farming in 1976 and the brand began in 1994, it has since been sold to the Ehrmann group in June 2024, but the dairy, the people and the farms are all right where they’ve always been.

We wanted a name that says clearly who we are and where we’re from, instantly recognisable as Cornish wherever you find us. The name has changed, but the recipes, the team, the farms and the standards all stay exactly the same.

All our milk comes from our own directly contracted farmers, every one of them based within a 25-mile radius of our dairy in Lostwithiel. It’s the same Cornish milk it’s always been.

No. Same recipes, same Cornish milk, same high standards, made in the same dairy by the same people. The only thing that’s changed is the name on the front.

The business is owned by the Ehrmann group, an independent 3rd generation family-owned dairy business with over 100 years of heritage. Production stays in Cornwall, with ongoing investment in our dairy, our local team and our Cornish farming partnerships.
