Comedian Simon Evans continues his series about the economics of some of the goods - or bads - we are addicted to.

What are the economics, history and health issues behind these oh-so-addictive commodities?

This time it's coffee.

How much are we now drinking as a nation? And how much of the price of a cup of coffee is actually the coffee beans? Are we giving coffee growers the best deal when we buy Fairtrade coffee or should we be seeking out Direct trade coffee? And could this be the least harmful of all addictions?

Perhaps even a positive addiction, with the coffee shop being, as Steven Johnson said (in his recent 'Where good ideas come from' TED talk), 'a place where ideas can have sex'?

Simon speaks to specialist coffee experts Onny Loisel and Michael Cleland.

He's also joined by economics guru, More Or Less host Tim Harford and the Queen of investment know-how, Merryn Somerset-Webb, as he walks us around the economics of this very familiar commodity and pokes fun at our relationship with it.

Written by Simon Evans, Benjamin Partridge and Andy Wolton.
