Cristalline Plus

Isinglass to assist with clarification and brightening

IOC CRISTALLINE PLUS™ can improve clarity and filterability even in difficult-to-filter wines (e.g., wines made with botrytized grapes).

• Generally used in white and rosé wines to increase brilliance
• It is favored by Pinot noir winemakers due to its gentle fining effect and brightening of aromas
• Works best when the initial solid levels are relatively low
• CRISTALLINE PLUS is not sensitive to cold temperatures but may be slow to complete settling; co-fine with GELOCOLLE for faster settling
• Blend of isinglass and citric acid stabilized with potassium metabisulfite
