Ok I made a 5 gallon batch from a extract kit. an amber red ale from a lbs. og was suppose to be 1.051 I got 1.053, fermentation went normally and after 14 days appeared to have stopped. I moved it to a secondary and took a reading 1.020, it should have been 1.012. I had no other activity in the secondary. I checked a week later and still 1.020. I rocked the carboy a little still nothing, I added a packet of safale us-05 and a few days later fermentation started again. after a week it dropped to 1.014. Three weeks later it was still at 1.014 but I still had some air lock activity. I bottled last Wednesday, last night I opened a bottle and had a geyser. leaving about 1/3 of the bottle left. I have the rest in a cooler, I have moved it outside the house in the cold. low 30s It tasted ok is there anything I can do to attempt to save this?
