One of the primary factors influencing the ripening process is the climate. "Sunlight and temperature warmth are vital to the physiological functions of the grapevine (such as photosynthesis).But when you experience excessive heat waves the vine enters a type of 'survival mode.' Less resources are directed towards the ripening and development of the grapes .Therefore the occurrence of heat waves we have been experiencing this year in the growing season, particularly as it nears harvestime, has caused sugars in grapes to jump as acids fall dramatically. Therefore your tannins and phenolic compounds may not be optimal ripe."
