So I have a 5 gallon batch of white muscadine must in primary. I pitched Red Star Pasteur Champagne yeast 2 days ago after hydrating it and then pouring into must. The must temp is approx 72-74 degrees F and still producing frothy bubbles when I gently punch down the cap several times a day. Yesterday I took a S.G reading and it dropped from the initial 1.090 down to 1.056. I took another reading again today and it was the same YET still producing frothy bubbles when I punch down slowly and gently. After reading, it sounds like once the S.G. levels out and remains the same for 2-3 consecutive days then the primary has completed. However, and this brings me to my question, as I said the bubbling is still quite vigorous at punch down. This is only the 3rd day after pitching yeast so would find it hard to believe that primary has already slowed down. If I am getting the same reading tomorrow yet still have the bubbles do I press and rack to secondary or keep it in the primary until they stop? I don't want to leave the skins in there too long as they will go bad nor do I want to rack and have it explode out of the carboy. Can anyone give some advice? Thank all
