Pembrokeshire potato producers, Trehill Farm, have dug up the ultimate accolade for their super spuds.

The Marloes farm was named as the decade's best producer at the tenth National Trust Fine Farm Produce Awards, which were held in London last night (Tuesday).

The farm's tenants, Peter and Gina Smithies, grow potatoes on 600 acres overlooking Marloes Sands and Skomer and Skokholm.

The couple took over Trehill Farm from Gina's parents in 2001 and have entered and won an award for their crop every year since 2007.

"This award gives our product a distinctive point of difference," said a delighted Gina.

"The high profile National Trust brand helps drive sales by linking the charity's core purposes with food production. The award itself gives us the confidence to present our potatoes to all customers, large or small."

National Trust general manager for Pembrokeshire, Jonathan Hughes, said: "I'm thrilled for Gina and Peter to have won this award. Not only have they consistently produced high-quality products, but they have farmed with biodiversity and conservation benefits in mind.

"Additionally, they have allowed improved public access and enjoyment on their land. So, this is a well-deserved accolade for their produce and the other benefits their efforts have brought."

The annual awards celebrate the very best produce from the National Trust's 1,500 tenant farmers and estates across England, Wales and Northern Ireland.

Products not only have to excel in the obligatory taste test, but entrants also have to pass a checklist of environmental standards to guarantee the quality and origin of ingredients alongside high standards of production.

The winners were decided by a judging panel consisting of ten food and drink experts, including representatives from Selfridges' food team.

Rob Macklin, Head of Food and Farming at the National Trust, and chair of the judges said that this was a "landmark year" for the awards with more tenants and food producers than ever before winning awards.

It is the first time that so many products met or exceeded the strict judging criteria of the conservation charity's food and farming awards.

"It really is the best way to mark the dedication and work our tenants put in to their businesses," he said.
