In viticulture, the yield is a measure of the amount of grapes or wine that is produced per unit surface of vineyard. Yield is an important quality factor in wine production.
In general, there is consensus that if vines are cropped with a very high amount of grape clusters, a poor wine will result because of slow and insufficient ripening of the grapes.
Natural vs Conventional Wines
The reason conventional winemakers believe they can make good wine from high yielding vineyards is that the quality of the grapes is relatively unimportant in conventionally made wines. Any lack of taste in the grapes can be compensated for in the winery. Which is too bad! I wrote about it in this article, Life is too short…
A naturally made wine relies for its taste solely on the grapes from which it is made. A great natural wine, one that truly expresses its terroir, can only be made from the low-yielding vines.
