What Wine Can Teach Us About Climate Change: Lessons from the Vine

Wine serves as a potent symbol of resilience in the face of climate change, with wineries and businesses challenged to adapt their operations sustainably. The Penedès region in Spain, rich with winemaking traditions dating back to the 7th century BC, now faces significant threats due to climate change. Following a past crisis caused by the Phylloxera bug in the 19th century, the current climate crisis could be poised to reshape the future of viticulture if swift, collaborative actions aren’t taken.

A recent study published in Nature Reviews Earth & Environment suggests that as much as 70% of today’s wine-producing regions may become unsuitable for grape cultivation if global temperatures rise over 2°C. Specifically, traditional wine regions located in coastal and lowland areas of Spain, Italy, Greece, and southern California are particularly vulnerable, with projections indicating up to a 90% risk of disappearance by century’s end, primarily from droughts and heatwaves.

Winegrowers have long noticed climate shifts, acting as early indicators of the environmental changes affecting agriculture. However, the Spanish wine sector’s response to these threats has been lethargic, with only recent strides toward necessary adaptation techniques.

Sustainability has emerged as a critical focus, influencing vineyard practices, wine production methods, and visions for future winemaking. In Penedès, all wines are now produced from organic grapes, marking a significant milestone in sustainable viticulture. Yet, there is a growing call for a regenerative agricultural model that enhances soil health and ecosystem resilience through practices like no-till farming, cover crops, and biodiversity enhancement.

Climate change is altering grape harvest timelines, leading to premature ripening and jeopardizing wine quality. Consequently, vineyards are shifting to higher elevations and adapting grape varieties to better withstand heat and drought. The industry has begun adopting lighter wine bottles and renewable energy sources, with reports indicating that 56% of Spain’s electricity came from renewables in 2024.

Efforts to absorb greenhouse gases are also crucial, with tree planting regarded as an effective strategy. Familia Torres has initiated extensive tree planting efforts in Chile and manages significant forest areas in Spain, promoting biodiversity and reducing wildfire risks.

Despite these initiatives, the climate crisis entails addressing fossil fuel reliance. Global oil consumption is alarmingly high, and ongoing governmental support in the form of subsidies continues to prop up fossil fuel industries, exacerbating the climate challenge. Plastic pollution further complicates matters, with its detrimental effects on ecosystems and human health becoming increasingly evident.

No sustainable vineyard can thrive in isolation; collaboration across the industry is essential. The International Wineries for Climate Action (IWCA) was formed to promote collective decarbonization efforts, combining the strengths of over 170 wineries from 14 countries, representing 3.5% of global wine production.

Ultimately, collective action is imperative to mitigate climate change and secure a viable future for viticulture and the broader environment. While challenges loom, the potential for impactful change remains if stakeholders across all sectors unite in determination and action.
