• Granular isinglass.
• Good for clarification and improving brilliance.

Recommendations: Reduce bitterness; clarification; brilliance.

Isinglass is a form of collagen obtained from the dried swim bladders of fish. Used to improve brilliance and clarity of wine, it also reduces monomers and smaller polyphenolic compounds responsible for wine bitterness. Isinglass is usually used as a final touch before bottling or even as a riddling aid for sparkling wines.
