Clone

Term
klown
In viticulture, a clone refers to wine grapevines that are genetically identical, and come from a single "mother" plant.
A grape clone is a cutting taken from an existing grapevine that’s grafted onto rootstock. The vine is chosen due to specific traits a grower wants to reproduce like, increased disease resistance or fruit quality. Clones allow vineyards to choose characteristics in wine grapevines that are tailored to the wine-growing region, thus producing consistent harvests and flavor characteristics, year after year.
