Dr. Johanna DÖRING

Geisenheim University, Institute of General and Ecological Viticulture

Dr. Johanna Döring is a researcher at Hochschule Geisenheim University (Germany), involved in research on organic and biodynamic viticulture.

She studied viticulture and enology in Geisenheim, Germany, worked in Italy as an enologist, and holds a PhD in agricultural sciences at Justus Liebig University Giessen, Germany.

She published several peer-reviewed articles about the effects of organic and biodynamic viticulture on biodiversity, plant growth, yield, and winegrape quality. The long-term trial comparing integrated, organic and biodynamic viticulture at Hochschule Geisenheim University is at the core of her research activities. Beyond that her research is focused on leaf area development of grapevines and on plant physiology including embolism formation under water stress.

Together with a colleague she runs a small winery in Geisenheim producing organic Riesling.

Worldwide Vineyards

In his book “La preuve par la greffe” (Proof through grafting), Lucien Daniel expressed his dismay in 1908: “What is more astonishing, in my opinion,… is that even today, there are people who are not concerned enough about the general interests of viticulture to prevent the truth from coming to light, instead of provoking and encouraging research on this crucial point”. These words from the great botanist sum up a career devoted to grafting.

For Marc Birebent, grafting may be the winegrower’s best ally, but it is also the gravedigger of the vine. A specialist in grafting, T-Bud and Chip-Bud grafting, his knowledge of soils, terroirs, climates, grape varieties and rootstocks make him a leading specialist. He and his team work in vineyards all over the world.
