In the short term, that has produced some "grands millesimes," the French term for stand-out years.
For Bordeaux, 1990, 2005 and 2010 have all been described as once-a-century vintages, while in Burgundy 2005 and 2009 are said to hold exceptional promise.
But in the long run - measured in decades - these conditions may evolve into something far less favourable, the study warned.
"If we keep warming, the globe will reach a tipping point," said Wolkovich, pointing to what happened in 2003.
During that summer, the thermometer climbed past 40C (104F) on half-a-dozen days in the Bordeaux region in early August.
"That may be a good indicator of where we are headed," she added. "If we keep pushing the heat up, vineyards can't maintain that forever."
In France, signature grape varietals - pinot noir in Burgundy, and Merlot in Bordeaux - will no longer be as well-adapted. Instead, southern England could become the new Champagne, with better climate conditions for Chardonnay.
In other wine-producing regions such as California and Australia, the solution may be to find new "terroir" better suited to these famous grapes.
