During the recession British drinkers traded up to more expensive, higher quality coffee. Sheila Dillon asks why, and what exactly is it that we're now pouring into our daily cup? She meets Jeremy Torz, director of Union Coffee Roasters, one of the first of a now growing number of small businesses sourcing and roasting speciality coffee beans. She hears from coffee writer Daniel Young who explains why London has become one of the most influential cities in the world when it comes to a making an espresso. Sheila also asks why, despite the success of the high street chains and more awareness of roast and ground coffee, most of us still turn to a cup of instant when we make a cup at home?
