Bud break signals the start of Napa Valley’s growing season. After winter dormancy and careful pruning, tiny buds burst open to reveal the first leaves and grape flowers. This moment sets the stage for a new vintage under the guidance of Winemaker Margo Van Staaveren.
What Is Bud Break?
Bud break is the first sign of life after winter in the vineyard. As ground temperatures rise above 50°F, dormant vines awaken and buds on each shoot begin to swell and open. These buds reveal the first leaves and the beginnings of grape flowers, which will eventually form clusters of grapes. In Napa Valley, bud break typically occurs in mid to late February, though timing depends on grape variety, soil, and weather conditions.
Before Bud Break: Winter Dormancy and Pruning
Following harvest, vines enter dormancy when soil temperatures drop below 50°F. During this period, sap stops circulating and leaves fall, leaving bare vines across the valley. This is the ideal time for pruning, a process that removes old shoots from the previous season.
Pruning is essential for controlling yields and ensuring vine energy is directed toward the right number of grape clusters. At Beringer, much of this work is done by hand because each vine grows differently and requires skill and precision. Pruning blends art and science, setting the foundation for a successful growing season.
What Happens After Bud Break?
Once buds open and shoots begin to grow, the vineyard transforms into a sea of green. From this point forward, Winemaker Margo Van Staaveren, who brings more than 45 harvests of experience to Beringer, makes critical decisions with her team to guide the vintage. They manage shoot thinning, water allocation, and vineyard floor maintenance to ensure the vines thrive and produce exceptional fruit.
Why Bud Break Matters
Bud break signals the start of a new vintage and a new chapter in Napa Valley winemaking. Every decision from this point forward influences the quality and character of the wines you’ll enjoy in the future.
