First off I've used unpasteurized cider for both- both gallons from different orchards. I should also mention that I'm very good about sterilizing everything!
The first time I brewed, I did a 1/4 of sugar, and half a can of condensed apple cider, with half a tablespoon of pectic enzyme. The cider never actually cleared up till about 2 weeks in, after the yeast had died off, and my cider was "mellowing" out.
This time, I did 3/4 cup of sugar and a tablespoon of pectic enzyme. It seems to be clearing, aside from from these odd little floating clouds.
My biggest concern is that I can't measure the temperate at the moment, but I fear my room may be a bit cold... Hopefully that's not the case, though, if it is, I am return home from school tomorrow where I can store my concoction in a more suitable space.
