The wine industry is worried about the effects that this phenomenon can result in grapes. Scientists seek to temper them. The Third World Congress Wine and Climate Change held last week in Marbella, the Master of Wine Country Pancho raised his glass to claim the Grenache, a "chameleon grape" as key variety in the adaptation of the wineries in Mediterranean countries to weather conditions tougher. The same conclusion was reached some months earlier, a group of experts at a seminar held in Barbastro (capital of wine country Somontano Aragon) with the same subject. They were launched several alerts. On the one hand, that the wines are more alcoholic (alcohol strength has increased, in some cases, of 10-11 º to 14 to 14.5 º), with more PH and lower natural acidity. On the other hand, some will lose their red color, other flavors and lost many qualities typical white varieties. It was also noted that perhaps, increase the proportion of reds against whites.
regard, Ignacio Fernandez, then Head of the Economics and Law at the International Wine Organisation (OIV), indicated that the native varieties, along with changes in field practices, innovation (to remove alcohol to wine through fermentation, for example) and research into new products, are the most important time to adapt. Meanwhile, to mitigate the effects, called for environmental management, reduced water consumption and CO2 emissions, a measure of carbon footprint and maintenance of the living trees with vines, like Aleppo or olive trees, not to convert those monoculture plantations.
Fernandez spoke of blossoms and grape harvests increasingly advanced and extreme weather events: peaks of high and low temperatures, longer dry periods broken by torrential rains. He referred to "temperature stress" of plants, as well as acceleration and maturity mismatches, lower productivity and risks of pests and diseases which now did not exist.
"Spain is one of the areas most affected by climate change," he said after noting how the increased degree of average global temperature shifts the limits of wine production 100 miles north. "The fact that there are now 1,000 acres of wine in the United States was unthinkable 150 years ago. Meanwhile, the southern boundary will be conditioned by the availability of water," he concluded.
According to the group of experts meeting in Barbastro, some effects of climate change are: Soups
more alcoholics, with higher pH and lower acidity natural.
Loss of color and flavor of some reds. Loss more alcoholics, with higher pH and lower acidity natural.
typical qualities in some white.
possibility of an increased proportion of red versus white.
