Yeast, Black Pepper, Crisp Flavour

Jimmy meets a man with one of the strangest jobs in the food industry, harvesting different strains of yeast from multiple locations across the globe. Matt's looking into how they get the flavours onto our crisps. Do producers use real cheese, onion, vinegar and salt - or are these actually artificial flavours cooked up in a lab?
