The book further notes that the first written documentation of mulled wines was around the 14th century A.D. "Cookbooks listed methods of mulling 'Clarrey' or Bordeaux. Recipes involved honey, cinnamon, cardamom, galingale and French wine."
In the Christmas Compendium by J. John, a comprehensive compilation of the A - Z of Christmas, he writes about Mulled Wine and its long association with the harsh winters of Europe and Middle-East Asia. "Mulled wines have a long history. In medieval times they were called ypocras' or hipocris', named after the physician Hippocrates. They were thought to be very healthy, and indeed with wine at that time being far more sanitary than water, these heated drinks in all likelihood did keep people healthy through the cold winters."
