A person who owns or manages a place where grapes are grown for making wine.
The vineyardist carefully tended to the grapevines to ensure a good harvest.
Vineyardist → It is formed from "vineyard" (from Old French *vignoble*, meaning a place where vines are cultivated) and "-ist" (meaning a person who practices or is concerned with something). A vineyardist is a person who works in or is associated with a vineyard, particularly in the cultivation of grapes for winemaking.
Think of a 'vineyard' as a place where grapes grow, and the '-ist' means a person involved in that activity. So, a vineyardist is someone who works with grapes in a vineyard.
