Wine aficionado and all round drinks expert Oz Clarke teams up with Hugh Dennis in a seasonal challenge to sample every Christmas tipple past and present.
The boys embrace the festive spirit as they attempt to uncover each drink's true Christmas credentials. From whisky and winter ales in the Highlands to mulled wine in the birthplace of Dickens; wassail in the West Country and sloe gin in Wiltshire; plus buck's fizz, port, sherry and snowballs too.
Oz and Hugh explore the weird and wonderful customs that surround each drink and even expose some as complete festive fakes.
And once the jolly is over and the lads are sober, they take their very own mobile bar - aka the booze bike - to the streets of London to dish out liquid gifts to the great British public and announce which drink deserves to become Britain's first official Christmas tipple.
