Which of the following is a characteristic of wines classified as IGT?

Wines classified as IGT, or "Indicazione Geografica Tipica," are known for having less stringent regulations compared to DOC (Denominazione di Origine Controllata) wines. This classification allows for greater flexibility in winemaking practices, enabling producers to experiment with different grape varieties and blends while still adhering to a geographic indication. This means that while IGT wines must originate from a specific region, the rules governing their production are not as rigorous as those for DOC wines. This flexibility often leads to innovative and diverse wine styles that showcase the characteristics of the region without being bound by the strict varietal and production rules imposed on DOC wines.
