THE VINE’S GROWTH CYCLE IV – VERAISON
During the veraison stage the colors of the grape take form-red/black or yellow/green depending on the grape varieties. This color changing is due to the chlorophyll in the berry skin being replaced by anthocyanins (red wine grapes) and carotenoids (white wine grapes). In a process known as engustment, the berries start to soften as they build up sugars. Within six days of the start of veraison, the berries begin to grow dramatically as they accumulate glucose and fructose and acids begin to fall
In Batea, this stage happen in august, and about 35-55 days later, the grape will be ready to be collected.
