Early winemakers tasted the grapes to gauge ripeness. The grapes reach full ripeness and produce complex, well balanced wine. Apples are first selected based on ripeness, texture, natural sweetness and tartness/acidity. The high yields and sub-alpine climate tends to produce Nebbiolo lacking ripeness with bracing acidity. Other considerations include phenological ripeness, berry flavor, tannin development (seed color and taste). It confers a tart taste to wine; the amount decreases with increasing fruit ripeness. Table grapes are a labour-intensive agricultural product that require harvesting by hand at peak ripeness. Historically the estate used different colour seals for grapes of different ripeness. Olive oil taste characteristics depend on which stage of ripeness olive fruits are collected. The light-green surface blemishes turn orange when the fruit is at its peak ripeness. There are several factors that contribute to the ripeness of the grape. Generally, the fruit is at its optimum ripeness the day it drops from the tree. Depending on the ripeness, the fruits are distinctively squarish and angular. The degree of ripeness has an effect on the flavour as well. The Federal District Court dismissed the suit on standing and ripeness grounds.
