Wine type refers to the classification of wine based on its characteristics, such as color, sweetness, and production method. The main categories include red wine, white wine, rosé wine, and sparkling wine. Each type is made from different grape varieties and undergoes distinct fermentation processes, which influence their flavors and aromas. Additionally, wines can be categorized by their sweetness levels, ranging from dry to sweet. Some wines, like dessert wines, are specifically crafted to be sweeter, while others, like brut champagne, are known for their dryness. Understanding these types helps consumers choose wines that suit their preferences.
