Which process removes solids from a cloudy wine by temperature adjustment, blending, filtering, or fining material?

• A. Fining
• B. Filtration
• C. Destemming
• D. Maceration

Answer: (A)

The method being tested is about clearing wine by adding a substance that binds the cloudy particles. Fining uses a fining agent (like gelatin, bentonite, egg white, or other materials) that attaches to suspended solids such as proteins, pigments, or tannins. These bound particles form larger aggregates that settle out or can be removed more easily, resulting in a clearer wine. This chemical/physical binding approach is different from filtration, which simply pushes liquid through a filter to physically remove particles, and from destemming or maceration, which are grape processing steps rather than clarification methods. The presence of “fining material” specifically points to this technique as the mechanism for removing solids.
