The notable characteristic of the climate in Burgundy during the harvest season is the frequent occurrence of frost and rain. Typically, September and October—the months when grapes are harvested—can experience significant climatic variability. The region is known for its cool continental climate, which can lead to conditions such as morning frosts and occasional rain showers that may impact the harvest.

Frost is a concern because it can damage the grapevines, delaying the harvest and potentially reducing the quality of the wine. Rain during this time can also affect the crops, leading to issues like dilution of sugars in the grapes or promoting rot if the conditions are too wet. While warm temperatures may sometimes be present, the unpredictability of frost and rain during the harvest season is much more defining for Burgundy's climate during this critical period. This characteristic outlines the challenges winemakers face, emphasizing why careful management and timing during the harvest are crucial for achieving optimal fruit quality.
