Forgive me if these questions have been asked a thousand times, but it is my first batch of cider. In a 5 gallon food grade bucket I added 4.5 gallons of Musselman's cider and a can of frozen concentrated. I had purchased some Lalvin EC-118 from Amazon a month or so ago and stored it in the refrigerator. I pitched the yeast is some warm water with some cider mixed in and saw minor bubbling in the pint jar. Not really knowing what to expect, I watched about 4 hours of less than vigorous yeast activity. I then mixed the yeast in the bucket, secured the bucket and loaded the air lock. After two days in a cool (about 65 degree) closet, I had zero bubbles in the airlock. I then mixed another package of yeast (bought 10 when I got them). This time I got a bit more bubbling activity so I decided it was probably bad yeast the first time. After a few hours, I poured the second batch of yeast in the cider. Two days later still no bubbles in airlock. Am I dealing with bad yeast? How long until I should be seeing bubbles? Is there something more I should do to the yeast to bring it along? I have 8 more packets. Should I keep mixing in yeast until it takes off? If you can tell where I went wrong, please let me know.
