THE VINE AND CLIMATE CHANGE

Basic information related to grape  

Knowing the grape, the cultivation of the vine, the winemaking, or its treatment is part of the training that students receive from our site. The viticulture and enology were both independent disciplines that enhance the former when judging the quality of the wine. Nowadays, it considered essential that a glass of quality wine made from excellent raw material. As the vineyard works or the quality of the same, they are part of the final product.

Although some still have doubts about the reality or not of the so-called “Climate Change,” the evidence is increasingly palpable.

  • Can this phenomenon affect the cultivation of the vine?
  • What effects can it have?
  • Can we fight them or alleviate them?

In recent months there have been significant hail storms in some areas, a phenomenon that could be directly related to climate control that some experts predict.

We will comment on this phenomenon, and how it affects the vineyard, the effects it produces, and the most recommended actions.

The end of spring and the beginning of summer are critical times for the development of the vine. The plant has bloomed in a phase of vegetative growth in which it absorbs water and nutrients from the soil. Moreover, it performs photosynthesis to produce the necessary energy that allows it to feed and have optimal development in the next process.

One of the greatest dangers for a vineyard at this time is hail, fortunately, unusual atmospheric phenomenon, but increasingly frequent. A phenomenon of this type destroys leaves, branches, and clusters information, being able to destroy the crop, or at least considerably decrease its quality. The effects could even compromise the next crop, depending on its incidence on the yolks and the leaf surface.

What to do when the harvest has suffered a hail storm?

In a period of fewer than 48 hours should apply healing treatments. It was borne in mind that the wounds produced by hail represent a gateway for all types of diseases, viral, bacterial, or fungal that will lead to loss of vitality and even the death of the plant.

If the vineyard is poorly affected, you must remove the damaged part and apply treatments against pests and diseases for improving the better conditions. 

When the plantation is moderately affected, the damaged parts also removed, and appropriate treatments are applied. Secondary shoots (grandchildren) should not be eliminated in these cases so as not to lose leaf area and thus facilitate the accumulation of reserves for the next harvest.

If the vineyard is very affected, it recommended a very severe pruning, even “blindly,” leaving a pair of buds per arm, to try the appearance of new shoots in the year, which allow the plant redirected during the next season.

Other signs of climate change mentioned below:

  • Torrential rains in normally dry seasons.
  • Unusual temperature falls ​​above the forty degrees observed in recent days.
  • Whether we believe in climate change or not. We must know in depth the plant of the vine and its biological cycle. You are applying the appropriate viticultural practices, experiments, and treatments as soon as possible. The vineyard can be prepared to face the changes imposed by nature anticipating future problems successfully.
