This morning I woke up and the house was damn cold. The thermostat was reading 55 didn't change much, but it was probably at that temp for at least 6 and no more that 10 hours before the furnace was refired. With my carboy sitting in the closet it's alway a few degrees cooler in there. Would that change in the temp have time to affect the fermentation. Oh I forgot to mention that the carboy has been sitting in the closet now for almost a week.
