Chocolate

S1 E2: We are, without doubt, a world of chocolate lovers. In Britain alone, people eat on average a whopping 266 bars each year. Feeding our insatiable sweet tooth requires a lot of raw cocoa beans, a lot of factories, and a lot of smart machines. Join us as we enter a Nestlé plant that produces over seven million bars of chocolate in just 24 hours. Then take a tour of the Thorntons factory in Derbyshire, where high-tech robots and a team of over a 100 people work together to make boxes of assorted chocolates by the millions... by hand.
