Traité de la vigne et de ses produits: comprenant: l'histoire de la vigne et du vin dans tous les temps et dans tous les pays, l'étude botanique et pratique des différents cépages ...

Published in the late 19th century, this comprehensive work by Ludovic Portes reflects the rigorous scientific and agricultural focus of the era regarding viticulture. Born out of the urgent need to address the phylloxera epidemic that devastated European vineyards during that period, the treatise served as both a historical account and a practical manual for vineyard management. It was intended for serious agronomists and professional viticulturists seeking to stabilize and improve production standards.

The design of the work is characterized by the encyclopedic approach typical of French agricultural scholarship of the late 1800s. Portes, a recognized authority in his field, curated an extensive survey of global grape varieties and wine history to provide a foundation for modern practice. The text is noted for its meticulous classification and technical detail, which solidified its reputation as a standard reference for students and landowners navigating the complex transition to modern viticultural techniques.
