Before Collecting Grapes, Winemakers Are Collecting Data

If you go to Napa Valley’s Vineyard 29 and walk around the crops, the grapes almost look like they’re in bandages. But the bandage is actually a water-measuring device that sends the results to a computer. The data helps take the guesswork out of assessing whether the grapes are healthy. It makes the wine better and helps produce stronger vintages.
