Area under wine grape cultivation is increasing in
semiarid tropical regions of India. There is lack of information
on role of rootstocks influencing must composition
and thereby wine quality under such climatic
conditions. Majority of area under table grape cultivation
is grafted on Dogridge rootstock, which is also been
used for wine grapes. Grapes harvested from vines
grafted on Dogridge were known to possess high potassium
resulting in high pH which has adverse effect on
wine quality. Hence, this study was initiated to understand
fruit composition and wine quality of 'Cabernet
Sauvignon' grapes grafted with each of the rootstocks
101-14Mgt, 1103P, 110R, 140Ru, Fercal, Gravesac and
SO4. Rootstocks significantly influenced many of the
must composition parameters such as sugars, organic
acids, phenolic compounds, potassium and pH. Significant
and positive correlation was observed between potassium
content, juice pH and malic acid. Rootstocks
101-14 Mgt and Gravesac accumulated more potassium
in fruits which also had higher malic acid and juice pH,
while it was least on 110R, 1103P, Fercal and SO4 rootstocks.
The potassium content in juice was directly related
to wine pH, wherein wines made from 'Cabernet
Sauvignon' grafted on 101-14 Mgt and Gravesac had
highest pH. Content of most of the phenolic compounds
in must and wine were significantly influenced by rootstocks.
There was more than two fold increase in the
total phenolic content from must to wines with highest
phenols recorded in wines made from fruits harvested
on 110R rootstock
