Are you planning on not carbing it? If your going to make still cider then backsweetening is an easy process. Just add sorbate and potassium metabisulphite after fermentation then sweeten to your liking. Of course if your planning on carbing your apfelwein, this process will not work for you. If your kegging it, you can also backsweeten and have it carbed. Some people will add a sugar substitue like splenda to backsweeten and carb, however, some say the taste is not as good. There are options...depends what your looking to do.
