What is the main goal of fining in winemaking?

The main goal of fining in winemaking is to stabilize the clarity of the wine. This process involves the addition of fining agents, such as bentonite, egg whites, or gelatin, which bind to unwanted particles, such as proteins, tannins, and phenolics, in the wine. These particles are then removed from suspension, helping to achieve a clearer and more visually appealing product.

Clarity is important not only for aesthetic reasons but also for the overall quality and stability of the wine; it can affect the perception of taste and mouthfeel, and it helps ensure that the wine will age well without developing cloudiness or other issues. Thus, fining plays a crucial role in producing a polished end product that meets consumer expectations.
