Argentine scientists from the Universities of Mendoza and Guymallén have found that vines in higher altitude vineyards can adapt better to climate change. This would result in the areas best suited for viticulture shifting to higher latitudes or altitudes. These are currently characterised by shorter growing seasons and lower summer temperatures. In the future, however, a wider range of grape varieties could be grown there, because then grape varieties with shorter growth cycles could also reach a higher oenological level.
The comprehensive report pointed out that "grapes from higher altitudes have higher anthocyanin content and higher acidity, mitigating the effects of climatic conditions that lead to premature ripening" and "wines from high altitude vineyards tend to have better colour, higher acidity and more desirable aroma profiles".
Conversely, it was also highlighted that current growing areas for premium grapes could suffer significant losses in quality due to the predicted rise in temperature and reduced water availability.
