There is no exact word in French for winemaker.
Answer: True.
It was in France that the fundamental concept of terroir as the dominant factor shaping a wine’s character became pervasive and flourished. Indeed, historically, the French have been so convinced that Nature makes the wine that there has never been an exact French word for winemaker. Instead, the term commonly used, vigneron, portrays man’s role as more humble. Vigneron means “grape grower.”
