Ehrmann Cornish Dairy invests US$25.3M in its Trewithen site

UK – Ehrmann Cornish Dairy, a German-based company, has unveiled plans for a £20 million investment in its new state-of-the-art chilled dessert production facility at the Trewithen Dairy site in Glynn Valley, Cornwall.

Scheduled to open in 2026, the facility will manufacture Ehrmann’s flagship ranges, including High Protein, Grand Desserts, and Robby, directly in the UK, reducing reliance on imports and strengthening supply chain resilience.

The company said the investment will support its UK growth strategy, enabling expansion into nationwide retail listings and greater flexibility to tailor products to local consumer preferences. The project will also create new opportunities in both innovation and manufacturing.

“This bold new chapter of Ehrmann Cornish Dairy reflects our ambition to grow a future-focused dairy business in the UK, based on innovation, sustainability and local sourcing. By bringing together Ehrmann’s global experience with Trewithen’s strong regional roots, we’re in a great position to serve both retail partners and consumers with high-quality, home-produced dairy products,” Ed Watts, chief commercial officer at Ehrmann Cornish Dairy.

The news follows the merger of Ehrmann and the Cornish-based Trewithen Dairy, which created Ehrmann Cornish Dairy and combined one of Germany’s largest privately owned dairy companies with the UK’s Cornish dairy heritage. The business serves as the UK home to both brands.

Paul Berne, CEO of Trewithen Dairy, said: “This partnership strengthens our position as a leader in Cornish dairy while accelerating out reach nationwide. With new investment, innovation and manufacturing capability, we’re well placed to continue growing our national presence without losing sight of our Cornish heritage.”

Ehrmann Cornish Dairy is positioning itself as a key player in the UK dairy and chilled desserts market with investment in domestic production and a strengthened brand identity. This growth is already being reflected through increased distribution of Trewithen Dairy products in UK supermarkets.

Trewithen Dairy launches new milk

Recently, the company introduced Cornwall Gold milk, expanding its offerings. The golden milk contains 5% fat, delivering a smooth, rich taste. Trewithen Dairy describes Cornwall Gold as a modern take on traditional gold top milk, with the cream blended throughout for a consistent texture and flavour.

The launch coincides with growing consumer demand for full-fat dairy and products made with fewer, recognisable ingredients, as shoppers move away from ultra-processed alternatives. Cornwall Gold is positioned to meet this demand with a focus on natural ingredients and traditional production.

Mark Moody, Marketing Director at Trewithen Dairy & Ehrmann UK, said: “We’re proud to be expanding our range with Cornwall Gold, a premium milk that showcases the quality of Cornish milk with delivering a beautifully blended, decadent experience. It’s a standout addition that strengthens our offering in the premium dairy space and provides retailers with a distinctive product to add to their shelves.”
