Cheesemaking couple Allison and Jonathan in Teesdale are determined to work and live sustainably on their smallholding and do it with gusto. But with a dairy, café and glamping huts to run, as well as animals to feed, selling their award-winning cheeses at Barnard Castle Farmers' Market in County Durham is a vital source of income.Jonathan is armed with samples of their new dessert cheese and is keen to coax customers to try before they buy. Meanwhile, near Darlington, Olly and Francesca, with help from mum Heather and their young daughter, are bottling up their home-grown rapeseed oil on the family farm. Francesca's keen eye for design means she's focused on making sure their bottles catch the eye of passing customers. Both families rely on Barnard Castle Farmers' Market for their livelihood, and it's full-on for five hours to secure a successful day's takings.
