Cornerstone Certified Vineyards

Rootstock and Budwood Cuttings

We are a participant in the California Department of Agriculture's Registered Increase Block program. Plants in our increase blocks (mother blocks) originally came from the California Foundation Block, managed by the Foundation Plant Service at UC Davis. This program goes to great lengths to insure the virus free status, origin, and trueness to type of all winegrape and rootstock varieties. This translates to the highest quality, cleanest material available to our customers. We offer the following rootstock and budwood varieties:
