More Information on Tall Grafted Grapevines

After some research on vineyards in our Southeastern New England AVA using tall grafted grapevines (Close Encounter with Tall/High Grafts, Visit with Rob Russell at Westport Rivers), we decided to order our grapevines from Mercier Nursery in Vacaville, CA. When we went to Vacaville in January of this year, Sebastian and Franco were in the midst of harvesting the rootstock (The Clones are Coming).
When we met Sebastian at the Wineries Unlimited Meeting in Richmond, VA, Sebastian said that he has an article (in German) on tall grafts. I recently did a Google search and found that a nursery in New Zealand called Ormond Nursery and Elite Nursery in Australia are providing their customers with tall grafted grapevines. There is more information on the links that gives details about the benefits of using tall grafted grapevines.
