I made hard cider this way: https://www.youtube.com/watch?v=G25FFvCpNoQ
except I also added cranberries, a couple tablespoons of sugar, and cinnamon. And yes, I used Fleischmann's rapid rise yeast. Today, after 2 weeks my airlock balloon deflated and I decided to bottle the hard cider. So, I combined everything that fermented with a little bit of water that I boiled and added a good amount of sugar to (so that the yeast hopefully feeds on it). I tasted it and it was mainly sour and odd tasting. No apple flavor and not sweet either. Is this normal? Why does this not taste that good? Can I fix this?
