Most vineyards around Pinhel and the wider Beira Interior are dry-farmed, on high granite and schist slopes with a harsh, dry climate. There's usually no irrigation to schedule — so grapestone isn't about telling you how much to water. It's about telling you, early, what kind of season your vines are heading into.

Without irrigation, this number doesn't tell you how much to water — there's nothing to turn on. Its value is in reading the season ahead of time: how fast your vines' water reserve is draining, and when real stress is likely to arrive.
That's useful in ways that have nothing to do with a tap: timing canopy work like leaf removal to manage how much water your vines demand, judging harvest timing and the sugar-acid balance you can expect, and spotting early in a dry year that yield or quality risk is building — while there's still time to plan around it.
What this replaces
Instead of only finding out how tough a season was once the grapes show it — smaller berries, stalled ripening, an unplanned early harvest — you get a running read on vine water stress building through the season, plot by plot.
A running picture of how fast your vines' water reserve is draining, ahead of visible signs.
Ground decisions like leaf removal and picking dates in what the vine is actually experiencing, not just the calendar.
Spot a tough season building early enough to plan around it — for yield, quality, and everything downstream of harvest.
No sensors to install, no irrigation system required.
Satellite imagery covers your hillside vineyard automatically, day after day.
Translated into a straightforward evapotranspiration estimate for your plot's soil and slope.
A plain-language sense of how much stress is building, and what that's likely to mean by harvest.
