Gelsol is used for static clarification of white musts or flotation and removal of astringent tannin in red wines.
Dosage: It always depends on the wine or must to be treated, and trials are recommended.
Must Clarification (with spindasol): Begin trials at 5 ml/hL (1/2 pound/1000 gals). Spindasol: 5-10x the weight of gelsol to compact.
Red Wines: Begin trials at 2.5mL/hL (1/4 pound/1000 gals). Spindasol: 3-4x the weight of gelsol to compact.
