Should we be taking water more seriously? The emergence of the water sommelier would suggest so. Jaega Wise visits a Cheshire restaurant that now offers its own water menu as well as a Peak District pub with a water bar and a borehole to draw its own spring water. She talks to the co-founder of the Fine Waters Academy Michael Mascha who believes that water should be appreciated as a product with its own terroir and hears from Dr Natalie Lamb, a water industry expert who has been trained to appreciate the virtues of tap water. Whether hard or soft, still or sparkling - the Food Programme takes a closer look at the liquid we all too often take for granted. Produced for BBC Audio in Bristol by Robin Markwell Programme contains a clip of the Only Fools And Horses Episode "Mother Nature's Son", written by John Sullivan, first broadcast on BBC TV on 25th December, 1992
