Do we pay enough for tea? Dan Saladino - a long-term and deeply committed coffee drinker - continues his look at our love affair with the leaf.

Dan catches up with the BBC's South Asia Correspondent Justin Rowlatt, who has reported on conditions for tea workers in Assam, India. He also discovers a world of 'rock-star' tea growers and learns how to tell the difference between CTC and orthodox tea - and why it matters.

There is also advice on how to make a 'nice cup of tea' from... George Orwell.
