Sparkolloid does have a disadvantage. It produces very fine lees, and the lees settle out slowly. Consequently, this material should not be used less than 30 days
before bottling time, or small amounts may precipitate later in the bottles. Many winemakers allow for an eight-week settling time just to be on the safe side...
These instructions come directly from Scott Laboratories (the manufacturer). Ignore the amounts as they are for a commericial winery, but note the stated process:
A. Preparation of Hot Mix Sparkolloid®
1. Heat to boiling point, 1-2 gallons of water per pound Hot Mix Sparkolloid® used (8-15L/kg). Slowly stir in the Hot Mix Sparkolloid®.
2. Maintain temperature above 82°C (180°F), while agitating the mixture constantly until all of the translucent globules of clarifier have been dissolved and the mixture is smooth and creamy (Approximately 20-30 minutes).
B. Addition to Wine
1. While still hot, slowly add the mixture to the wine. This is easily accomplished by pumping into the vortex of a GUTH agitator or by introducing the hot Sparkolloid into the line while pumping over.
2. Let the wine settle one week or more, depending somewhat on the volume of wine involved, then filter, preferably from the top of the tank.
You will note that these instructions mention "1 week", but that assumes the product will be filtered via a commercial filter. Home brewers should wait at least 30 days before racking after using Sparkalloid.
