But what are the effects of using rootstocks on wine quality? I was fortunate enough to have been involved in a number of rootstock comparison trials undertaken by the Roseworthy based Grape and Wine Research in the 1990's.
Rootstock
The use of separate rootstock - essentially a clump of roots - onto which the vines are grafted was made necessary by the arrival of Phylloxera.
Rootstock
The lower portion of a root and its corresponding growth buds, used for vine propagation.
Rootstock: The root system of the grapevine to which a fruiting vine of any desired variety, such as Merlot, Cabernet Sauvignon, etc., can be grafted.
Rootstock
Because of the consequences of the deadly root disease phylloxera, most vines in commercial vineyards are now grafted onto a suitable American variety (these are resistant to phylloxera).
rootstock
Bottom part of an American vine, including the roots, into which the Vitis vinifera is grafted.

Rootstocks: Riparia Gloire, 143A, 1613, 1616, 3309,
SO4, 5BB, 5C, 101-14, 125-1, 188-15.
Vines: Chardonnay, Riesling, Pinot Noir, Merlot,
Cab. Sauvignon, Muscat Ottonel, Aligote,
Pinot Gris, Gewurztraminer, Cab. Franc.
Rootstock:Disease-resistant native American grapevine grown specifically to provide a root system on which to graftVitis viniferavarieties. Most of the world takes these measures to prevent attacks of phylloxera.
Chardonnay: Rootstock from the U.S; golden to amber; fruit aromas of apple, pear, bananas.
Chenin Blanc: Ideal grape for hot areas; good acidity and flavor; compatible for blending. Argentina's grape of the future.
Research the rootstocks that are appropriate for your climactic conditions.
Use of a resistant rootstock, promoted by Thomas Munson, involves grafting a Vitis vinifera scion onto the roots of a resistant Vitis labrusca or other American native species.
BudwoodThe varietal grape that is grafted onto the rootstock. This is the part of the vine that produces the fruit.
Grafting onto resistant rootstock has been key in fighting phylloxera and other vine diseases. Grassing-down allowing grass to grow between the vines as a means of combating soil erosion.
These vineyards were saved by grafting European (Vitis vinifera) vines onto Phylloxera-resistant American (Vitis labrusca) rootstocks. Irony abounds because the infestation came from vines imported from the United States.
Recommended for grafting to the 3309 rootstock in New York state where it has shown good winter hardiness. Ohio researchers are currently (1999) testing the 1616 and 18-815 rootstocks.
The decay of Rioja began when phylloxera spread in the region and by the consequent discovery of the remedy for this parasite - by using immune rootstocks - and French enologists decided to come back to their homeland and to restore the production of ...
MICHURINETZ: East European extreme-winter hardy grape of astonishing vigor derived from numerous varieties of european vinifera, plus amurensis rootstock. The name is apparently an anglicized version of "Miczurinoweic".
The vine itself is prone to vigorous yields, particularly when planted on the vigorous SO4 rootstock. Excessive yields can result in less concentrated and flavorful wine with flavors more on the green or herbaceous side.
These slips are usually grafted onto rootstock that has been specially cultivated to combine growth vigor with resistance to disease. They are then put into sand for one season. This is called bench-grafting.
So, there began a long, laborious process of grafting every wine vine in Europe over to American rootstocks. It was only in this manner that the European wine industry could be retrieved from extinction.
A European wine grape best known not for its wine quality but for its original use as a parent in producing the hybrid rootstock AXR-1.
Devastated Europe in the late nineteenth century until it was discovered that American rootstock was resistant. Since then, most European vines are grafted onto American rootstock.
vinifera vines that have been grafted onto North American species rootstock. This is common practice because North American grape species are resistant to phylloxera, a root louse that eventually kills the vine.
The ultimate solution to eradicate this Attila the Hun pest was to graft vines on to American rootstocks that resisted the phylloxera.

Flooding the vines and using carbon bisulphide to kill the pests both worked, but both were very difficult to carry out on all vineyards. The answer came in the realization that American rootstock had long since developed a resistance to this louse.
phylloxera - fatal vine pest which chews vine roots. The only remedy is to replant on phylloxera-resistant rootstocks.
potential alcohol of a liquid is the acoholic strength it would reach if all the sugar were fermented into alcohol.
T budding - A technique that permits grafting of different grape varieties onto existing rootstocks in a vineyard.
T.B.A. - An abbreviation for the German wine Trockenbeerenauslese.
The property consists of a 33-acre block that was planted with Sauvignon Blanc rootstocks back in 1980, and now also is home to some Pinot Noir plantings.
The vineyard's location, climate, terrain, soils, vines and rootstocks, irrigation systems and pest management controls all factor into the final product in one way or another.
As a result, most new vineplants are grafted onto a phylloxera-resistant rootstock to ensure proper vine health and adequate bearing. Phylloxera remains a problem in most of the world's vinifera vineyards.
some of the vine species originating in North America, such as Vitis rupestris and Vitis riparia, could cope with Phylloxera. These vines did not produce attractive wines, but by grafting a cutting of Vitis vinifera onto an American vine rootstock, ...
Originally from America (where native vines were resistant) this disease has caused widespread global damage. New vineyards are being planted on American resistant rootstock grafted with 'vitis vinifera' grape varieties.
