Case Study: The International Organization of Vine and Wine assesses severe weather impacts and prepares for climate risk with Meteomatics

Severe Weather and Rising Demand for Wine

The International Organization of Vine and Wine faced a major production shock in 2021 as late spring frosts and prolonged summer rains sharply reduced yields across Europe — OIV reported volumes down about 4% versus 2020 and 7% versus the 20‑year average, with reports of frost affecting up to 80% of French vineyards and heavy losses in Champagne. Meteomatics supported analysis of these events using its hyperlocal weather and climate services (high‑resolution 90‑m datasets, 2m air temperature and frost warnings, soil moisture indices and long‑range climate projections).

Meteomatics delivered detailed charts and analyses—frost warnings for Burgundy and Tuscany, soil moisture indices, and localized climate projections—that linked specific frost and rainfall events to vineyard damage and mildew outbreaks. By quantifying and visualizing the weather’s role in the estimated production declines (including localized figures such as ~30% Champagne losses and mildew impacts of 20–26%), Meteomatics provided The International Organization of Vine and Wine and industry stakeholders with actionable attribution and planning data to guide short‑term responses and longer‑term climate adaptation.
