Wine characteristics refer to the various attributes that define a wine's profile, including its aroma, flavor, acidity, sweetness, and tannin levels. These elements are influenced by factors such as grape variety, terroir, and winemaking techniques. For example, a Cabernet Sauvignon typically exhibits bold flavors and higher tannins, while a Chardonnay may present a creamier texture with fruity notes. The balance of these characteristics determines the overall quality and enjoyment of the wine. Acidity adds freshness, while sweetness can enhance flavor complexity. Understanding these traits helps consumers select wines that suit their preferences and occasions.
