Terroir is a French term that refers to the unique environmental factors that influence the characteristics of agricultural products, particularly wine. It encompasses elements such as soil composition, climate, topography, and local traditions. These factors work together to create a distinct flavor profile and quality for products grown in a specific region. The concept of terroir highlights how the same grape variety can produce different wines depending on where it is cultivated. For example, grapes grown in Bordeaux will taste different from those grown in Napa Valley, even if they are the same type. This diversity is what makes regional products unique and valued.
