The French ampelographer Paul Truel (1924-2014) is considered one of the world's leading experts in this field. He studied at the Department of Viticulture at the French University in Montpellier (Languedoc). This was at the time when Pierre Galet (1921-2019) was head of the viticulture department there. Like Galet, he was an absolute specialist in the identification of grape varieties, which he could often identify spontaneously and purely visually on the basis of the phenotype. Paul Truel was for many years in charge of the INRA (now INRAE) grape variety collection at the Domaine de Vassal.
For my many years of work as an editor with a wine and culinary focus, I always like to inform myself about special questions at Wine lexicon. Spontaneous reading and following links often leads to exciting discoveries in the wide world of wine.
