#crop failure
- To remain unripe — To stop growing and remain in an unripe, green, and sour state; a regional viticultural term used to describe the phenomenon where grape berries halt their development and fail to mature due to drought, diseases, or pest attacks, retaining their astringency and green coloration.
- Ripening failure — The act of turning into verjuice or failing to ripen and its result; a regional physiological or pathological process described in viticulture whereby grape berries stagnate in growth and remain small, green, and sour. This structural phenomenon is caused by climate stress factors such as severe drought or pathogenic attacks, compromising the normal ripening of the yield.
