Grafted vines have been widely used in Australia for decades. They consist of a scion – the fruiting part of the vine, that is grafted to a stock – the rooted part of the vine (hence the rootstock).
Variety identification is important to grape growers, winemakers, regulatory authorities, those who sell wine and those who consume it. An estimated 5000 to 6000 varieties of the Vitis vinifera species exist around the world, although only a relatively small number of these are used commercially. Historically, Australian winemaking has been based on the classical varieties but in the last 20 years there has been an increase in interest in less well known, or alternative, varieties.
The examples of sources have focused on those varieties originally from Portugal, Spain, France, Italy and Greece because those countries are more likely to provide varieties suitable for a hot dry climate than those from northern Europe.
On the same site, with identical management practices, different grapevine varieties generally ripen at different rates. This is due to the genetically determined behaviours of the grape varieties, in combination with their interaction with the site. Good varietal selection is important if crucial stages of development are to occur in favorable conditions.
