When it comes to wine, it doesn’t get much more traditional than Bordeaux.
The region has been making wine since Roman times. It’s been favored by European royalty for centuries, and Thomas Jefferson was a big fan.
Bordeaux has been highly regulated and tightly controlled since the Classification of 1855, when the region’s producers were sorted by quality into First through Fifth “Growths.” For more than eight decades, the appellation has allowed only ten grapes to be used in wines bearing its name.
But that may be about to change.
The reason? Climate change.
