from my exp , here is what i know, fermented apple juice is called
Cider aside from one type of super dry german cider made in one small region in germany. Unless you are make that you are makeing cider. there is lots of types out there and lots of good information and trial and error, if you want to experiment be my guest, however
if you want to make a spiced apple cider (this has been done 1000s of times) i would use some malt to add more body, if you want make it dryer add some dextrose or honey thay dont have protins or dextrins so thay only add alcohol and that = dryer.
also i would not use the montserrat yeast i think that would be a horrible pick.
so at this point , you have something nothing like an Apfelwein, so you should not use it as a refrence point , as EdWort has said him self inregards to other cider ideas refencing apfelwien "that sounds good but its not an apfelwien".
as for the yeast i whould use a hefeweizen yeast or english ale yeast.
please read these two threads to see some of the trial and error wizdom
