Climate and Grape Growing
🌤️

Climate Characteristics

  • Moderate maritime climate.
  • Influenced by the Gulf Stream, which:
    • Extends the growing season.
    • Reduces the risk of spring frosts.
    • Allows grapes to ripen into October.
  • High levels of rainfall and humidity due to proximity to the Atlantic.
🌳🏖️

Geographical Protection

  • Protected from severe Atlantic storms by:
    • The Landes forest.
    • Coastal sand dunes to the west.
🌧️

Challenges

  • Rainfall throughout the year causes:
    • Disruption of flowering and fruit set.
    • Increased risk of rot.
    • Dilution of grape flavors at harvest.
  • Significant vintage variations require careful management.
🍇✨

Producer Solutions

  • Top producers mitigate challenges by:
    • Discarding unhealthy and unripe grapes.
    • Managing style and quality differences between vintages.
🌡️🌱

Impact of Climate Change and Techniques

  • Warming climate and advanced canopy management result in:
    • Healthier grapes.
    • Reduced use of sprays.
    • Increased sugar levels and enhanced flavor development by harvest.
