Summer is the first season that Greg Wallace looks at and there is everything from how bananas are ripened in massive storage facilities through to how a new strawberry is developed for Sainsburys. For any convenience store retailer this is a must watch. You can watch the first program here   (only available on the BBC iPlayer until 9.59pm on 11th July 2013).

Episode two was on BBC One at 9 pm on October 30th when Greg looked at Autumn.
