California grape growers drowning in unsold product as wine demand falls

California's Napa Valley is experiencing a crisis as grape growers find themselves with surplus grapes due to a significant drop in wine demand. This downturn is causing financial strain for the farmers, with many grapes left to rot in the vineyards. The shift in consumer preferences and possibly economic factors contributing to the reduced demand highlights a troubling trend for one of the state's major agricultural sectors. This situation underscores the vulnerability of the wine industry to broader economic changes and consumer behavior shifts.
