Climate change, particularly heat waves, has been progressively advancing the harvest calendar. This phenomenon has been observed year after year, with producers adjusting their agricultural practices to the new weather conditions.
However, the anticipation of harvests does not depend only on climatic conditions. The wine style that producers intend to make also directly influences the decision of when to harvest the grapes, since the harvest timing determines the final characteristics of the product.
Labor availability constitutes another relevant factor in this equation. The hiring of workers for grape picking can condition the timing of harvests, adding a logistical variable to the equation.
Thus, although climate change is the main driver of harvest anticipation, multiple factors interact to determine the exact moment of harvest, creating a complex challenge for wine producers.
