Rootstocks Grape Varieties
2 grape varieties from Rootstocks.
110 Richter (110R) Rootstock
Rootstock
One of the most widely used rootstocks in warm, dry wine regions. 110R is a cross of Vitis berlandieri and Vitis rupestris that provides strong drought resistance and moderate vigor. It delays ripening slightly compared to own-rooted vines, which can be an advantage in hot climates. Standard choice in California, Australia, and the Mediterranean.
$2 - $5 per rootstock
SO4 (Selection Oppenheim 4) Rootstock
Rootstock
A widely planted rootstock in cooler European wine regions, selected at the Oppenheim Institute in Germany. SO4 is a berlandieri x riparia cross that promotes early ripening and moderate vigor. It works well in heavy, moist soils where deep-rooted stocks would struggle. Good for cool-climate sites where every extra day of ripening counts.
