The 2024 harvest across Europe has underscored the profound effects of climate change on viticulture, presenting winemakers with a season marked by extreme weather and challenging conditions. The result was a vintage of contrasts, characterized by lower yields but a welcome resurgence in acidity, an essential quality for producing well-balanced wines.
Spring brought consistent rainfall across much of Europe, leading to high humidity levels in vineyards. This created an ideal environment for fungal diseases, particularly downy mildew, which significantly impacted regions such as the Loire Valley. Areas like Menetou-Salon and Pouilly-Fumé recorded historically low yields due to the ongoing disease pressure. The situation worsened through the summer as cool, damp conditions delayed grape ripening, limiting sugar accumulation and prolonging the growing season.
Late summer and early autumn posed additional challenges. September rains exacerbated the vineyard issues, fostering botrytis and sour rot, particularly in lower-lying, more vigorous plots. However, these same conditions helped preserve the acidity levels that had been lacking in previous heatwave-driven vintages. To combat these challenges, winemakers adopted precise management strategies, such as rigorous vineyard selection and careful monitoring in the winery, ensuring only the highest quality grapes were harvested.
In Italy, regions like Tuscany and Bolgheri experienced similar weather disruptions. The cool, wet season slowed grape ripening, leading to lighter wines with lower alcohol content and higher acidity, reminiscent of classic vintages from the 1980s and 1990s. Despite reduced yields, careful agronomic and enological practices ensured the quality of the harvest remained high.
Spain was not immune to the unpredictability of the 2024 climate. Recent decades have seen a trend of earlier budburst and ripening, along with higher sugar levels in grapes, resulting in wines with higher alcohol content and reduced acidity. However, the cooler, more temperate conditions of the 2024 season allowed for a more balanced development, especially in Rioja and Ribera del Duero, where the grapes benefited from slower ripening and an improved sugar-acidity balance.
Bordeaux, famous for its Cabernet Sauvignon, also faced significant challenges. The region’s cool temperatures and frequent rainfall hindered optimal grape ripening, leading to potential issues with underripe fruit and green flavors in less carefully managed vineyards. Nevertheless, many producers in Bordeaux turned to more traditional winemaking styles, producing wines with lower alcohol content, greater freshness, and improved acidity.
In southern France, the Languedoc region enjoyed more moderate conditions compared to recent years. Typically subjected to extreme heat, Languedoc benefitted from cooler nights and substantial rainfall during the ripening period. This fostered more balanced grape development, resulting in wines with a refreshing acidity and enhanced freshness—an appealing departure from the overly ripe, structureless wines often produced in the region’s hotter years.
The 2024 harvest serves as a clear example of how climate change is reshaping European viticulture. Extreme weather patterns have forced many producers to reconsider their approaches, balancing the challenges of hotter years that accelerate ripening and boost alcohol levels with cooler seasons like this one, where maintaining vineyard health and preserving acidity took precedence. Acidity, long prized for its role in producing balanced and age-worthy wines, saw a resurgence in 2024, especially in regions like Champagne, Albariño, and Sauternes.
This year’s vintage highlights a division in how winemakers view climate change. Some see warming conditions as beneficial for specific grape varieties or northern regions, allowing for more consistent ripening. However, the 2024 season emphasized the value of returning to more classic styles in traditional regions, where the focus shifted toward freshness over power.
Despite the difficulties posed by the weather, winemakers’ adaptability and meticulous attention to detail helped mitigate the challenges of the 2024 harvest. Through innovative techniques and careful grape selection, many were able to turn a difficult season into an opportunity to produce wines that highlight the timeless qualities of balance, freshness, and elegance.
