What is Bud Break? This isn’t just a beautiful site, it’s when the ground warms up as hormones activate in the roots and tell the vine to grow in order to produce all of the wines we love to drink.
The bud break stage begins around March with the “bleeding” of the wine, when the warm soil and osmotic forces pushes water, containing a low concentration of organic acids, hormones, minerals and sugars, up from the root system and it is expelled from the cuts left over from pruning the vine.
Did you know that during this period a single vine can “bleed” up to 1.3 gallons of water?
Bud Break is also known as the “green point.” Each bud contains all of the ingredients in tiny forms—shoots, leaves, tendrils and berries that are not yet grapes. When the sap starts to flow, the grapes will begin to grow.
Pruners leave two buds on each spur carefully in place in order to provide growth and eventually, the bounty of the wine.
The energy to facilitate this growth comes from reserves of carbohydrate stored in the roots and wood of the vine from the last growth cycle.
A thin web of cottony fibers, much like a spider’s web called the tomentum, first protects buds. This shatters as leaves first start to appear, in the beautiful flowering of the bud.
Each Varietal has a different and defining appearance, with the cabernet sauvignon being radiant with color.
The buds form tiny shoots that eventually sprout tiny leaves that begin photosynthesis to produce the energy to accelerate growth into the next cycle.
