grapestone turns satellite imagery into a simple, plot-level estimate of how much water your vineyard is losing to sun and wind each day — so you can act on it, whatever your setup looks like.
Every day, sun, wind, and dry air pull water out of the soil and out of the vine's leaves. That combined loss is called evapotranspiration — it is, in effect, what your vineyard spent in water that day.
Knowing that number precisely, plot by plot, tells you what has already been spent — which is the starting point for almost every decision you make about water, whether or not you have a tap to turn.
What you do with that number, though, depends a lot on how your vineyard is run. That's why we built a separate page for each region instead of one generic pitch.
Irrigation habits, climate, and what's actually at stake differ sharply across Portugal's wine regions. See what this means where you are.
Widely irrigated by drip. Get a clear, weekly number for how much and when to water.
Read more →Hot, dry, and water is often scarce or rationed. Make every drop count.
Read more →Mostly no irrigation. Know what stress is coming before it shows up in the grapes.

Satellite imagery covers your vineyard automatically, day after day, with no sensors to install or maintain.
The imagery is translated into a straightforward evapotranspiration estimate for your specific plot.
Delivered in plain terms — how much water your vines used, and what that means for your next decision.
