I put my first batch of cider in primary on 2/26. The recipe was as follows:
2.5 gallons apple juice
1# light brown sugar
4 oz. lactose
1 packet Nottingham ale yeast
It started fermenting right away and was going steadily for several days before it began to trickle to about 1 bubble every 20-30 seconds. Now I have no activity in my air lock. Should I be concerned? I'm using an ale bucket for my fermenter and the temp was consistently around 68 and 70.
