Hard Cider/Apfelwein Experiment

I was recently given a bunch of empty one-gallon wine jugs from my wife's grandmother that I was really excited to fill with random test batches of beer/wine/mead/cider/whatever I could think of. Last night, I decided to make a few batches of hard cider. I made two using Musselman's Apple Cider from Walmart and another batch following EdWort's Apfelwein recipe that I found on a homebrewing website.

Batch 1:
1 gallon Musselman's Apple Cider
1/20 of a teaspoon Pectic Enzyme
1 tsp. Yeast Nutrient
Red Star Montrachet Yeast
1.054 OG

Batch 2:
1 gallon Stop & Shop Apple Juice (not from concentrate)
.4 lbs corn sugar
Red Star Montrachet Yeast
1.064 OG

Batch 3:
1 gallon Musselman's Apple Cider
1/20 of a teaspoon Pectic Enzyme
1 tsp. Yeast Nutrient
Red Star Premier Cuvée Yeast
1.054 OG

I have the jugs sitting on the stairs to my basement at a reasonably constant 62 degrees (ambient). In a month, I will either rack them to a secondary vessel or bottle them, depending on how they look at the time. They will be ready for consumption in 9 to 12 months.
