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

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

Answer: (C)

Clarification through a fining agent is the process being described. Fining involves adding a substance that binds with suspended solids and colloids in the wine. These bindings form larger particles that settle to the bottom or are easier to filter out, leaving a clearer wine. This approach targets the microscopic or colloidal haze that won’t easily drop out on its own, making it a controlled way to remove cloudiness.

Temperature adjustment can cause some compounds to precipitate, but it’s not about introducing a material to bind and pull out the haze. Blending with a cleared wine dilutes solids but doesn’t remove them. Filtration physically strips particles, but the method described emphasizes using a fining material to actively bind and remove the suspended substances.
