Couple weeks ago, i bought a gallon of apple cider, not apple juice, at the grocery store, found that it had some type of preservative and just decided to wing it, its only a gallon. However i ran out of yeast and i had bread yeast on hand so i pitched some of that. OG was around 1.05 with a cup of table sugar added. Three weeks later its down to 1.003 however the taste is rather sour.
My question- since i really had no hopes in the first place, my question is it normal under these conditions to have a sour taste to it. I can taste the apple"ness" but boyy is it sour. thoughts suggestions and btw this is my first attempt at hard cider.
