Career

Guyot is remembered for making improvements in the cultivation and preparation of grapevines for the production of quality wines. He introduced the Guyot system of "cane-pruning" of vines for trellises. The Guyot system is extensively used throughout vineyards in Europe. The terms "single Guyot" and "double Guyot" are used for different techniques in the training of vines. His best known written works are: Culture de la vigne et vinification, and Étude des vignobles de France, pour servir à l'enseignement mutuel de la viticulture et de la vinification françaises. The latter work concerned Guyot's six-year research (1861-67) of vineyards in 71 departments throughout France.
