What is the function of fining agents in winemaking?

Fining agents play a crucial role in the winemaking process by clarifying the wine. They work by binding with unwanted particles, such as proteins, tannins, or other solid materials that can cause cloudiness. When these agents are added to the wine, they aggregate these particles into larger clumps, which then can be easily removed through various methods, such as filtration or settling.

The clarification process not only improves the appearance of the wine but also can enhance its stability. A clear wine is often more visually appealing and is considered a sign of quality by consumers. While fining can indirectly influence flavor and aroma by improving the overall condition of the wine, the primary function is specifically to remove unwanted particles and achieve clarity.
