James and Martin are in their adopted US home in Ohio to brew the ultimate Columbus collaboration beer. With local breweries Land Grant, Seventh Son, and Rockmill they head to the Blue Jackets ice hockey rink to brew a beer with buckeye nuts, which are unfortunately poisonous.

James and Martin make the Ultimate Beer and Cider Shandy with Simon Wright, the founder of Hawkes Cidery, and they do it in the most British way possible: while stuck in traffic at the top of double decker bus.
