The French oenologist Prof. Dr. Denis Boubals (1926-2007) is one of the most important personalities of the 20th century in viticulture. After graduating from high school, he studied at the University of Montpellier, graduated in oenology and agronomy in 1948 and obtained his doctorate in natural sciences in 1958 with a thesis on the genetic transmission of phylloxera resistance. Boubals first worked at the INRA (Institut National de la Recherche Agronomique) as the responsible director of the research department. In 1975 he got a chair for viticulture at the university department "École Nationale Supérieur Agronomique" in Montpellier. He founded an experimental station in Villeneuve-les-Maguelone in the département of Hérault and carried out his pioneering research on the causes of the fungal diseases powdery and downy mildew, phylloxera control and the DNA (genetics) of grapevines. As part of the modernisation of viticulture, he advocated the replacement of old local varieties with Cabernet Sau vignon, Sauvignon Blanc, Merlot, Chardonnay and also others, which earned him the nickname "Apôtres du Cabernet Sauvignon" (Apostle of Cabernet Sauvignon).
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
