 The text discusses how scientists have discovered that white grapes contain the same pigments as red grapes, but in smaller quantities. This means that white wine can also have a reddish color due to the presence of anthocyanins. The researchers found that certain compounds in the grape skin, such as flavonoids and phenolic acids, contribute to the color of the wine. They also discovered that the acidity of the wine affects the color, with higher acidity resulting in a more intense color. The study suggests that winemakers may be able to manipulate the color of their wines by adjusting factors such as grape variety, ripeness, and acidity levels.
