I am making my first Cider. It started out being a bit acetic however, it has not dropped in ph. I was ablw to start my brew at 1.065 and in four days it fermented to 1.000. I tasted it after these four days to get an idea of where it was at, and it tasted a bit sour. I am hoping that this is the taste of an imature cider with no sugar. I added four more pounds of sugar to keep the fermentation going after racking it of it's lees, and added some yeast nutrient. I am hoping that it is not turning to vinegar though. Should cider fermented for four days tast like this? What do you guys think? Any help would be great!
