Which of the following is a requirement for labeling a wine as "organic" in Italy?

To label a wine as "organic" in Italy, a key requirement is that the grapes must be grown without the use of synthetic pesticides. This aligns with the organic farming principles that emphasize sustainability and environmental responsibility. Organic certification standards are designed to promote practices that enhance biodiversity and soil health while minimizing chemical inputs. By growing grapes without synthetic pesticides, vineyards not only comply with organic regulations but also improve the overall quality of the wine by fostering a healthier grapevine ecosystem. This practice is crucial because it ensures the purity of the vine's growth environment, directly impacting the characteristics of the wine produced.
