I am new to winemaking. I have made wine once before, but it was from a kit. I recently began making blueberry wine from fresh blueberries. I am currently in the primary fermentation phase, or so I think. When I added my smashed blueberries and sugar, I got my specific gravity to 1.096 before adding the yeast. I attempted to rehydrate the yeast with water, but honestly don’t know how to tell if that was done correctly. The bag did not start floating to the top until approximately a day and a half to two days after adding the yeast. There were bubbles around the rim but not a lot. I am using a bung and airlock and there are very slow bubbles in the airlock. I have been pushing the bag down with a spoon twice a day. It has now been about 6 days since I first added the yeast and I took the specific gravity today and got 1.079. Has fermentation started for me?? If not, what can I do to fix it?
