Boycott Farm Shop, which is based in Welsh Lane in Stowe, opened its doors in 2001 to sell surplus eggs provided by the farm's flock of 6,000 free-range hens.

In 2006, it widened its services to sell home-produced meats and home-cooked meals.

Since 1920, the farm has been owned by the Hilsdon family who bought it from the Stowe Estate, and it is now run by Richard and Rosemary Hilsdon.

The farm shop has recently undertaken a major expansion, moving the retail area into a restored, listed barn with a butchery and tea room.

The shop specialises in food produced on the farm, including Aberdeen Angus beef and Gloucester Old Spot pork, and other food sourced locally.

Mr Hilsdon said: "We have our own farm butcher, so the beef and pork are our own. The lamb is sourced from Radclive and some of the meat is cooked to make the food and meals we produce in our kitchen. We try to source locally as much of the produce as we can."

Honey is sourced from Ged Marshall, from British Honey Producers Ltd, in Steeple Claydon, while jams and chutneys come from Dadford. Cheeses are also sourced from the Oxford area.

Mr Hilsdon added the appeal of the farm shop had increased as more people were interested in knowing where their food came from.

He said: "People are definitely wanting to buy things which are produced locally and they want to know where it comes from.

"This farm shop has been open for five weeks and has really taken off."
