With harvesting nearly complete across much of central and southern England, Charlotte Smith visits a flour mill to find out about what this year's wheat is like.

John Lister of Shipton Mill in Gloucestershire buys in the top 2% of grain, much of it grown close to him in the Cotswolds. But because the prices for grain are set overseas, as a global commodity, he explains that his online flour business has to update its prices every half hour. A far cry from when he began milling flour in the 1980s, when prices were more stable than they are today, and set more at the county-level than in Chicago.
