There are several main types of wine, primarily categorized by their color: red wine, white wine, and rosé wine. Red wine is made from dark-colored grape varieties and typically has a rich flavor profile. White wine is produced from green or yellowish grapes and tends to be lighter and crisper. Rosé wine is created by allowing the grape skins to have brief contact with the juice, resulting in a pink hue. Additionally, wines can be classified by their sweetness levels, such as dry, semi-sweet, and sweet. Dry wines have little to no residual sugar, while sweet wines contain higher sugar levels, making them taste sweeter. Sparkling wines, like Champagne, are carbonated, adding a bubbly texture, while fortified wines, such as Port, have added spirits to increase alcohol content.
