Jerez is one of the oldest wine producing towns in Spain. Around 1490 trade had been established with the French and the British. The French and British adopted their own names for the wine which is why you will see all three names one a label of Xeres. (Jerez / Xerez /Sherry) The global positioning of the Jerez region plays a big part in regulating its climate. Like many semi-coastal regions, the ocean winds have a strong influence on the weather. In the 1800's, a vine disease called Phyloxerra destroyed many varieties that once grew in this region. Of the three grapes planted in Jerez today, Palimino accounts for 95 percent of the total vineyard area.
