Uses: Sparkolloid (AKA Celite, calcine diatomaceous earth, kieselguhr, siliceous rock) is a positively charged fining agent for beer and wine. Noted for working when other fining agents have failed. Also provides a compact sediment bed, pressing down other fining agents and increasing yield. Used as a coating medium for filter pads, to decrease porosity.
Directions: To use, stir 25 g of Sparkalloid into 1 L of briskly boiling water. Boil for 3 minutes, stirring well to compltelty dissolve. Use 12.5 mL of the prepared solution for every litre of wine (about 300 mL for 23 L). Stir thoroughly into wine, leave for 2 weeks, and then rack off the sediment. Will keep for 6 months or more. 5 mL (one teaspoon) = approximately 1.2 g
Composition: Crystalline Silica, quartz aluminosilicate, cristobalite. Although it may contain some colloidal compounds which can make it a gel, Sparkalloid is derived from preserved skeletons of marine animals found in dry seabeds, suspended in powdered agar gelatine.
Storage: Store in a tightly sealed container in a dry environment at room temperature.
