Clear as brilliant glass in 48 hrs.
Homebrew shops sell them as "Super Kleer"
Roger,
I assume when you use "Super Kleer" you would backsweeten first (I plan to use concentrate) otherwise it would just get cloudy again. Is that correct? So my steps would be stabilize, backsweeten, and super kleer then keg and carb.
Yes, that would be the order I use as well (remember that backsweetening with juice or concentrate can bring additional pectins in). Again, you will get a more clear and brilliant product if a positive and negative charged clarifier are both used. It's a good idea to run fining trials before you chuck this stuff into your full batch.
Some additional quick notes on clarifiers taken from a professional hard cider class taught by Peter Mitchell:
Pectinase- This is more of a pressing aid than a clarifier that needs to be added to the mash when the apples are being ground, prior to pressing, and held at 30 °C for 15min to 2 hrs. Do not add at the same time with another enzyme or clarifier, as it will be absorbed or inactivated.
Bentonite (- charge) : attracts positive charged yeasts and proteins. The lees are fluffy and not as compact. Hazardous to breathe the dust it produces. This stuff is a booger to handle and use, but relatively cheap to buy. Low potential to over fine. Does not usually affect color or tannin, but can affect overall product quality.
Gelatin (+ charge) : attracts negative charged bacteria and polyphenols. Lees aren't as fluffy as bentonite. Can easily over fine. Will strip color and tannin. Less likely to affect overall quality compared to bentonite.
Chitin or "chitosan" (+ charge) : a good all around flocculating agent, very compact lees, good product quality, Does not remove color or flavor, more expensive than other finings, potential allergen from crustacean (made from ground crab shells)
Kieselsol (- charge) : a good flocculating agent if used with gelatin or chitin, medium priced, made from silica
Isinglass (+ charge) : very gentle fining, not very efficient, medium price point, potential allergen from fish (made from fish bladders)
NEXT STEP UP would be to use a wine filter
Principles of Good Fining-
~ mix the agent well (follow manufacturer guidelines)
~ allow to stand
~ add slowly to cider
~ mix well into the cider
~ allow to stand undisturbed
~ keep cool temperature constant
~ use a tall narrow diameter vessel
~ use a +/- joint agent combo
