The annual Rare Beer Challenge, designed to raise money for Rare Disorders NZ, is on this year at Auckland's 16Tun, which takes over from the defunct Fortune Favours as the show host. Martin visits 16Tun owner Ewen Thorpe to find out how a one-time member of the Team NZ yachting crew ended up owning a waterside bar. Ewen also has great insights into the state of the beer economy from the POV of a bar owner.
