Based on the work of the French physician and scientist Dr. Jules Guyot (1807–1872), who developed instruments for measuring the sugar content in grape must (a "glucometer" or must-meter) to determine the ideal time for harvest and fermentation, his seminal studies and practical techniques were largely published in the 1860s.
Dr. Guyot conducted extensive research on viticulture and winemaking across France, culminating in his major work Étude des vignobles de France (1861–1867).

Key Publications:
He published Culture of the Vine and Wine Making (Culture de la vigne et vinification) around 1865.
The Instrument: While often described in the context of his "Guyot system" of training vine canes, Dr. Guyot created and advocated for the use of must-meters (instruments to measure must density and sugar/glucose content) during this period to improve wine quality.

Dr. Guyot's work was focused on the "sugar" (glucose) in grapes, but this was a wine-specific, analog must-meter, distinct from modern blood glucose meters developed in the 1970s.
