Looking at the history of the world through it's 6 favourite drinks might seem a bit unusual. But this lens throws light on changes in culture as well as power throughout the ages.

Tom Standage, editor of The Economist, took this approach in his book "A History Of The World In 6 Glasses," in which he traces trends through the history of Beer, Wine, Spirits, Tea, Coffee, and Coke.

Tom joins me for a chat focusing on the first three of these (though we'll probably mention the others as well.)

How did each influence the civilisations of their times? What do they say about the transfer of power and wealth across the ages? And which is better????
