Weekly Wine Defined – Bud Break

The start of the grape vines’ growth cycle begins in the spring with bud break. The small buds on the vine start to swell or “break” out and shoots begin to emerge from the bud.
The buds have been hanging out since the previous summer. During the winter, they turn brown and go dormant. Then when the weather turns spring-like, tiny green shoots emerge from the buds. This growth is energized from carbohydrate stored in roots and trunks. Soon the shoots sprout leaves and photosynthesis begins. Six months later, it’s harvest time.
