World Winery Map Digitizes 4.3 Million Vineyards and Their Terroir Data Amid Climate Change

UMAG, Croatia, Sept. 18, 2026 /PRNewswire/ -- As climate change rapidly redraws the historical boundaries of global viticulture, satellite topographical measurements and climate indices are now freely accessible on the most comprehensive wine map in history.

WorldWineryMap.com has officially launched, introducing a massive interactive database of global wine terroir that maps 4,303,693 vineyards and 104,330 wineries across 90 countries. For every single vineyard on the map, users can access highly specific geospatial data, including elevation, solar radiation, and slope, alongside critical viticultural metrics like soil composition, the Huglin index, and average temperatures during the vine growing season.

"For each parcel, we extracted the exact coordinates and calculated the elevation, slope, and aspect using the Copernicus GLO-30 terrain model, then layered climate data on top of that," said Matija Gavrilovic, founder of World Winery Map. "For larger parcels, we measure up to 16 control points, which is why elevation is presented as a precise range rather than a single number. We also calculated the slope, rainfall, wind, soil type, and geology wherever data was available."

The vineyard parcels are aggregated from 38 independent sources. Twenty-two are official government registers, accounting for 3,824,217 of the mapped plots. Data coverage is densest in the European Union, where such registers are public domain. In other regions, vineyard data is sourced from national agricultural censuses, satellite land cover analytics, and other unofficial sources.

The map outlines 98,719 specific wine region boundaries, scaling from massive macro-regions down to individual named plots. This includes 2,815 official wine regions, subregions, and appellations, alongside 95,904 named vineyard sites. The platform is tailored for both industry professionals and wine travelers. An integrated geolocation system allows users to instantly locate nearby wineries and receive navigation instructions to the estate, regardless of where they are in the world.

Crucially, wine areas are recorded using the exact boundaries and legal nomenclature designated by their respective nations. This includes INAO delimitations in France, AVA borders in the U.S., Wine Australia's Geographical Indications, ministerial decrees in Spain, Chile, and Romania, state geoportals for Austrian Rieden and German Weinlagen, as well as national regulations in Croatia, Hungary, and Slovenia. Users can select any region to read essential facts, review borders, check average rainfall and elevation, and analyze viticultural data like the Winkler index. World Winery Map is already in touch with official bodies in several countries, with the aim of keeping the map as accurate as possible.

"Building a system of this magnitude required processing more than four million geospatial polygons and precisely intersecting them with topographical and climate layers," the founder noted. "The result is the most comprehensive digital archive of world viticulture ever created."

Winemakers worldwide are invited to claim their winery profiles on the platform for free. By taking ownership of their pages, producers can update tasting room hours, verify visitor policies, claim their specific vineyard parcels, and update data on planted grape varieties—actively participating in maintaining the world's most accurate and detailed wine map.
