During the Age of Enlightenment, advancements in science ushered in a new occupation of "wine doctors" who could fashion examples of wines from obscure items and chemicals. Writers like Joseph Addison wrote of this "fraternity of chymical operators (sic)" who would use apples to make Champagne and sloe to make Bordeaux and then sell these wines fraudulently on the market. Following the Phylloxera epidemic, when true wine was scarce, wine fraud rose. Some merchants would take dried raisins grown from other species of grapevines and make wine that they passed off as being from a more prestigious provenance such as the more well known wines from France or Italy.
