Jimmy Doherty, Kate Quilton and Matt Tebbutt continue to reveal the secrets of the food on our supermarket shelves.

Tonight Kate journeys to the mountains of southern Peru, home to some of the world's finest coffee, before visiting one of Europe's largest coffee makers to learn about the astonishing freeze-drying process that turns coffee beans into everyday instant granules.

Jimmy immerses himself in vodka and wonders what is the difference between the high-end expensive stuff and the cheaper versions? Is it really worth splashing out on?

And Matt gets up close and personal with a flock of dairy sheep as he investigates Wensleydale cheese.
