Rootstocks

We produce the majority of our required rootstocks as table grapes in the varieties 125 AA (clone FR 26), SO4 (clone FR 78) and 5 BB (clone FR 148) in our own parent garden in Oberkirch. We obtain the remaining rootstock from carefully selected propagation farms. Every year, all the plants from which we obtain wood are intensively inspected by the breeder and by us. These checks include the general state of care, single-variety, wood maturity and, in special, the state of health with regard to fungal and viral diseases.

The rootstocks we use for our grafting combinations are exclusively pre-basic or basic material and have undergone extensive virus testing. Our strict quality controls guarantee the health and vitality of our grafts. We are your partner for healthy and high-quality planting stock!
