Grafting

Technique of joining fruit-bearing vines (usually Vitis vinifera) to rootstocks, usually of other Vitis species.

Since the outbreak of phylloxera in the nineteenth century, most of the world’s vineyards have been planted with vinifera vines grafted onto rootstock of vines native to America, which are resistant to phylloxera. Different rootstocks are chosen to suit soil type and to manipulate yield and vigour.
