Add Kiesesol first, but only after the wine has been stabilized and degassed fully. When adding stir in gently for 20 seconds then wait at least 1 hour (anywhere between 1 hour and 24hours) before adding Chitosan. When adding Chitoson, stir in gently for 20 seconds then leave to stand until completely clear.
Kieselsol and Chitosan are used for clarification of fermented beverages such and beer and wine. Rapidly clears out haze and cloudiness.
