It becomes stronger and loses the "typical" aftertaste. You'll have to adapt.
It is generally accepted that various soil and geographical conditions affect the taste of wine. Fans of this drink even have a taste map by region that has been developed over the years. But global warming could change the standard, says culinary historian and associate professor of history of science at the University of New Haven Gabriella M. Petrik.
In your new research for the University of Stavanger in Norway, she notes that climate change is affecting the taste of all types of wine, from reds from Bordeaux in France to light whites common in northern Italy. Therefore, the cultivation of some grape varieties is already shifting north to the UK and Germany.
Petrik believes that the taste guilt evolved much longer than previously thought. But winemakers are only now beginning to adapt to new realities.
For example, France has allowed the use of six new grape varieties - four red and two white - with high acidity for blending in Bordeaux wines. Older ones no longer give French wines a "typical" aftertaste. Because of the warming, they have become too much sugar and not enough acidity.
They want to add some acidity so that the wines are not too strong.

And the cultivation of Pinot Noir, another traditional French variety, is shifting closer to Germany as the weather warms. This is also one of the ways to maintain the traditional balance of sugar and acidity.
In the future, manufacturers may have to use a number of other strategies to maintain "typical" taste characteristics of their region or adapt to the cultivation of grapes in other countries, concludes Petrik.
