I finally found a recipe worth making in large batches. I've spent 6 months or more fermenting apple cider now and have made everything from plain/dry to cinnamon to well just about everything I can think of. I've used brown sugar, agave, vanilla sugar, and table sugar. I've used candied...
Your standard cider looks/sounds correct but I don't think you really need the yeast nutrient. Then again, I've never used that particular strain of yeast (I usually go with S-04, S-05, or liquid cold) so if it is turning out well for you then keep doing your thing.
Frozen berries: Hmmm...
