Silica gel for improved settling
Gelocolle is an aqueous solution of suspended silica commonly used in conjunction with gelatins, isinglass and other organic (protein-based) fining agents. It initiates flocculation of fining agents and helps lees compaction. It also reduces the risk of leaving residual protein-based fining agent behind (overfining).
Gelocolle can be used for hard-to-filter wines where it helps chelate proteins and other compounds.
Bench trials recommended for wine
200–1000 ppm 20–100 mL/hL 0.75–3.8 L/1000 gal
Note: Use 1.0 mL of Gelocolle to 1.0 mL of gelatin.
Gelocolle should be added directly into wine 1 hour after addition of protein-based fining agents (gelatin, isinglass, etc.). Mix thoroughly.
Dated expiration. Store in a dry, odor-free and well-ventilated environment below 25°C (77°F). Reseal opened packaging immediately. Do not refrigerate or freeze! Gelocolle solidifies at temperatures of less than 0°C(32°F). This process is irreversible.
