I have a batch of cranberry/cherry/orange that is on day 4. The yeast did not become very vigorous, and it is now just mildly fizzing. I took a gravity reading. the starting gravity was 1.1. On day 4 it is now at 1.06. Is it doing okay, or is there something I need to add to it? Is it okay that I transferred it to a carboy and airlock today?
