Which statement about soil fertility and wine quality is supported by practice?

• A. High fertility produces better wines
• B. Fertility has no impact on wine quality
• C. Low fertility produces better wines
• D. Medium fertility produces the best wines

Answer: (C)

Vine quality and wine flavor hinge on how much vigor the soil allows the vines to express. When nutrients are limited, the vines grow less vigorously and set fewer grapes, which tends to concentrate sugars, phenolics, and flavor compounds in each berry. That concentration often leads to better balance, more intense aroma and structure, and ultimately higher-quality wine. The practice of deficit or restricted fertility aims to keep yields in check so the fruit ripens fully without becoming diluted by excessive foliage or overly lush growth. Of course, pushing fertility too far the other way can stress the vines or reduce yield too much, so the aim is a controlled limitation rather than starvation. This is why the statement that low fertility produces better wines aligns with observed practice: restricted nutrients can enhance grape concentration and wine quality.
