What is Polyclar primarily used for?

Polyclar is primarily used in brewing and winemaking as a fining agent. Its main function is to clarify and stabilize beverages. When added to beer or wine, Polyclar binds to suspended particles, including proteins and polyphenols, that can cause haziness. This binding allows these particles to flocculate, or clump together, making them easier to remove during filtration or sedimentation. As a result, the final product is clearer and more visually appealing, and stabilization helps prevent unwanted changes in clarity or flavor due to microbial spoilage or protein-polyphenol interactions over time.

The other options do not align with the primary use of Polyclar. It does not enhance flavor, ferment sugars, or add bitterness; thus, its role is specifically linked to the clarity and stability of the beverage.
