 The cold and the rain proved to be particularly disastrous from 1315 to 1317 in which poor weather interrupted the maturation of many grains and beans and flooding turned fields rocky and barren.Scarcity of grain caused price inflation, as described in one account of grain prices in Europe in which the price of wheat doubled from twenty shillings per quarter in 1315 to forty shillings per quarter by June of the following year.Grape harvests also suffered, which reduced wine production throughout Europe.
