For that Skeeter Pee - Have you used Chitosan? Using it with Bentonite gives you both the + and - particle collection from the wine. I've had success using the two as a one-two punch in clearing some stubborn wines.
Here's an excerpt from the link at the bottom of my post:
1.
Bentonite
- negative charge
- continuously effective
- can be added at any stage
- creates compact lees
- be sure to mix thoroughly
Negatively-charged bentonite will attract and bind to positively-charged particulate matter such as dead yeast cells (lees). It is unique in that bentonite can be added before or after fermentation, and is especially effective when added prior to primary. The action of CO2 gasses produced by the yeast will continue to stir the bentonite during fermentation, and a buildup of lees will form in the bottom of your fermenter indicating the bentonite’s activity. Be sure to mix bentonite with warm water
thoroughly – if it is poured directly into wine it will clump up and lose efficiency.
2.
Chitosan
- positive charge
- very effective clarifying action
- minimal impact on flavor and character
- can be used in low-tannin environments
- use with Kieselsol
- be mindful of shellfish allergies
Chitosan is a positively-charged fining agent made of chitin, typically from the shells of crustaceans and other shelled microscopic sealife. It will attract proteins, yeast, polyphenols and other negatively-charged particles, and is especially effective when used with its partner Kieselsol (which has a negative charge). One excellent property of Chitosan is that it does not require tannins to work properly, allowing its use in white wines, ciders, meads, and more. Many experts say that Chitosan will not trigger shellfish allergies, especially if proper settling and racking takes place, but we advise caution.
