Help! I made a 5 gallon batch of fresh pressed apple cider. I pitched US-05 with 1 cup of brown sugar at room temp (~70). I put the carboy out of sight and out of mind for 3 weeks. When I went to rack to second fermentation bucket and check, nothing happened! same gravity = apple juice. I pitched a second packet of US-05 and some energizer 72 hours ago and still no activity! WTH am i doing wrong?
