Grapes shared Tut's table with watermelon. Shriveled fruit along with containers of wine accompanied the boy pharaoh in his tomb. Grapes and their fermented juice were already ancient additions to the menu by Tut's time. Archeologists found the first evidence of grape cultivation and wine making in what is now the nation of Georgia from 8,000 years ago.
On the other side of the Atlantic, another variety of grape grew in North America. In more recent history, those American grapes saved the vines of the Old World. In the 1860s, an insect pest, known as the Phylloxera aphid, attacked the wine grapes of Europe. The flow of fine wine from France, Germany and Italy dried up, until scientists discovered that grafting the European vines onto American roots protected them from the pest.
Now, wine faces another threat as climate change pushes the frontier of grape cultivation further north, yet renders more southerly regions unsuitable.
