I have no idea what a 'mother' is, but if it fermented well, you caught a natural yummy strain of yeast and you should keep it for sure. If you keep it in the refrigerator it will keep for a while. You may want to try a starter before trying again w/ some apple juice to make cider/apfelwine w/ it again but I've never tried w/ natural wild yeast. Sounds awesome!
