Inside the Factory: Season 3, Episode 6

3 - 6: Soft Drinks

Gregg Wallace explores Ribena's Gloucestershire factory. Meanwhile, Cherry Healey is in the lab figuring out why fizzy drinks are so appealing, and historian Ruth Goodman is working out why we associate barley water with the Great British summertime. The connection dates back to 1934, when the marketing team from Robinson's made up a batch to rehydrate the players at Wimbledon.
