Fining

Fining meaning in winemaking

Fining treats wine with an agent that interacts with selected compounds, which can then be separated from the wine. Winemakers use it for clarity, stability, or texture, with small-scale trials guiding the treatment.

Unlike filtration, fining is a treatment rather than simply passing wine through a filter. Timing and dose depend on the wine and product; there is no single schedule suitable for every treatment.
