Acorn Dairy was awarded the Tye Trophy for the Tyne Tees region from the Yorkshire Agricultural Society at this week’s Great Yorkshire Show in Harrogate.
The accolade recognises the efforts of the Tweddle family to operate a successful business while conserving the environment and boosting animal welfare.
It is the latest in a line of awards for the farm which became organic more than a decade ago.
Last year, Acorn Dairy was awarded an organic ‘Oscar’ by the Soil Association and the Good Dairy Award by Compassion in World Farming, the international welfare campaign group.
Brother and sister Caroline and Graham operate farms at Archdeacon Newton, Darlington and Spennithorne, near Leyburn.
The organic farming movement, which rejects artificial feeds, insecticides and the over-use of antibiotics in favour of natural processes, is concentrated in the South West of the country.
But Acorn Dairy decided to convert to organic more than a decade ago and has built up a loyal following of 4,000 customers, schools, cafes, restaurants and supermarkets including Waitrose and Morrisons across the North East and North Yorkshire.
Chairman of the judging panel Charles Mills said: “In all the years I’ve been involved in judging this competition, this year’s regional winners are amongst the finest.
“What struck us was that, not only do we have enterprises that combine good conservation practices with running a commercial business, but a host of new jobs have also been secured and created.”
Caroline said: “Organic farming is in our blood and something we all feel passionate about. Running a business should not be at the expense of animals or the environment and I think the success of Acorn, with the support of all our loyal customers, proves that ethical practices also make commercial sense.”
