I just brewed a spiced ale last night and my brew has been sitting in the primary fermenter for about 12 hours now and there is very minimal/no activity going on in the airlock. Previous brews I have done have seen very vigorous fermentations withing the first 12-24 hours but I think there is something wrong with this batch and I can't seem to figure out what. The room where my brew is sitting is hovering at around 60 degrees (it may drop at bit at night). If anyone has any suggestions as to what is going on or if you can give me an idea how to get the fermentatin kick started I would greatly appreciate it.
