Months after the harvest was completed, hundreds of thousand dormant grapevine canes begin the process of forming a perfect union between the rootstock and the graft material bud.

The union of sorts, called a scion, sounds quite simple, but in reality, the process allows a single rootstock to produce grapes from any variety of grapes. It has become the primary means for developing vines in the early stages of growth.
