🌿 Budbreak
The vine's spring awakening, when the first leaves emerge from the buds.
Budbreak is the spring awakening of the vine, when the first small leaves appear from the buds. It is the start of a new grape year. In winter the vine sleeps, and in spring, when it gets warm, sap begins to move in it.
When does it happen? Usually in March or April in the northern hemisphere, when the average temperature stays around 10 degrees. The exact time depends on the variety and place. Early varieties wake up earlier, late ones later. In warm areas it happens earlier, in cool ones later.
The main danger of this time is frost. Tender young leaves and shoots cannot stand the cold, and a late frost can destroy a large part of the crop. So growers watch the forecast and sometimes use fans, heaters or smoke to protect the vines.
After budbreak the vine moves on to flowering, then fruit set and ripening. Budbreak is the first point in the annual cycle of the vine.
