A condition in grapevines where flowering fails or develops improperly, resulting in few or no grapes being produced in that season.
From French coulure, derived from couler (to flow or run). The term suggests the flowers or developing fruit are flowing away or falling from the plant.
Coulure is a vintner's nightmare—entire vineyards can go from bumper crops to nearly nothing in a single season due to weather stress, which is why wine harvests vary so wildly year to year!
