hey guys. a month ago i brewed my first mead. og was 1.084. so today, 30 days later, i racked it to a carboy and took a reading. 1.030. the instructions said to keep the mead stored at 75-80 degrees. i kept it on my heating vent but most of the time the temp in my house is 65-70. did i mess up my mead or will it finish out? any help is greatly appreciated.
