Cheers! Rise and shine, little bud!
The grape starts its annual growth cycle in the spring with bud break.

Inside the buds contain usually three primordial shoots. These buds appear in the summer of previous growth cycle green and covered in scales during winter until the spring, when the vine begins the process of bud break and the first sign of green in the vineyard emerges in the form of tiny shoots. The energy to facilitate this growth comes from reserves of carbohydrate stored in roots and wood of the vine from the last growth cycle.
