How Superior Grapevines are Produced: Grafting

Welcome to part two of our vine production outline! We are thrilled to have you on this journey through the fascinating world of grapevine propagation! We trust that our last e-blast was not just informative but also sparked some interest for what comes next. As we dive into the stage of grafting, we want to remind you there is still time to contact us to secure your 2025 potted greenvine / 2026 dormant bareroot orders! We are in the midst of grafting and have just begun producing custom orders for 2026.

Following disbudding, the rootstock and scionwood for the grafted order is then sent to soak in a custom quaternary ammonium salt disinfectant for 4 hours, as a second method for sanitation.

Prior to grafting, the rootstock is given a fresh cut to the bottom of the vine to stimulate root growth. The scionwood is either cut manually or by our French bud cutting machines.  

This innovative method utilizes precise measurements to automate cuts above or below buds based on captured images of each vine, guaranteeing a consistent and high-quality result.  

At the stage of grafting, the scionwood and rootstock are joined together mechanically by our deep omega graft union method. Superior to a traditional omega union, the deeper cut allows for a much stronger connection of the cambium tissue of both scionwood and rootstock. The grafter will carefully select each scionwood and rootstock with similar diameter to connect the two pieces.  

It is crucial to note that at EVERY step of the way, from field to finished vine, our Quality Control teams are inspecting the quality and key indicators of each production process. This rigorous oversight ensures that each vine not only meets but exceeds our high standards of excellence, reinforcing our reputation as the number one trusted partner for grape growers.
