But the business has now expanded rapidly - to the extent that the farm now delivers around 47,000 boxes a week to homes around the UK. To match the demand, Riverford Organic have formed a mutual cooperative of British farmers around the country.
The weekly boxes come with a newsletter explaining the content of the box, giving farm news from Riverford and providing appropriate recipes.
The firm believes in good food, good farming and good business - everything that the firm produces is 100 per cent organic.
And it’s not just boxes of spuds and carrots Guy loves experimenting with new crops and other products.
Customers can order everything from vintage cheddar cheese to clementines, hazelnut truffles to fresh turmeric and everything in between.
Customers can specify the type of veg they want in their box – with a bewildering range of options. And it’s not just vegetables, Riverford Organic Farms are now a one-stop shop for fish, herbs and spices, mushrooms, organic meat, classy regional cheeses and even wine.
For keen cooks, or those looking for inspiration, Riverford also delivers seasonal recipe boxes complete with absolutely all of the ingredients needed to produce complete meals, from squash, kale and Stilton pie to chicken and mushroom stew with juniper and smashed celeriac.
