The Digital Terroir

"Great wine is made in the vineyard. We just measure the weather that made it happen."

Our Mission

For centuries, knowledge about wine vintages was locked away in the heads of local farmers or behind the paywalls of elite critics.Grapeyear exists to democratize this data.

We believe that objective climate data—rainfall, temperature, sunlight hours—tells the true story of a vintage long before the first bottle is uncorked. Our mission is to give collectors, investors, and enthusiasts the raw intelligence they need to make smarter wine decisions.

How it Works

  • Data Aggregation: We process millions of weather data points from global stations in top wine regions.
  • The Algorithm: Our proprietary 'Grapeyear Score' analyzes Growing Degree Days (GDD), Diurnal Range, and Rainfall timing to objectively rate vintage potential.
  • Transparency: No biases, no pay-to-play. Just pure numbers.

Who looks at weather charts for fun?

We do. And we think you should too. Because in a world of changing climates, the old rules of "good years" and "bad years" are being rewritten. Grapeyear is your navigator in this new landscape.
