Brewed up a Two Hearted clone the day after Christmas with the brand new burner Santa brought for me. Was shooting for a 1.072 OG, but since it was my first time using my new burner, way underestimated the boil off volume and only ended up with a little under four gallons of 1.083. Used a starter (1056) and got it down to 1.014 after a couple of weeks, transferred to the secondary and dry hopped for a week. Bottled on January 19th. Had the bottles sitting in our basement - about 50-55 degrees. After a couple of weeks I cracked one open and there was no carbonation and tasted super sweet (priming sugar). Realized it was probably way too cold down there, so I brought them up and put them on top of the fridge in our kitchen (65-70 degrees). Two weeks later, just cracked open one and still very little, if any carbonation. Are these beers screwed? Anything I can do to save them? Should I have added more yeast when bottling? Any help is greatly appreciated!
