Well I have 4 in primary and secondary and I am so excited for those I had to start some more. I gotta give credit to Pyro, he is the one that gave me some advice on this one.
******EDITED FINAL RECIPE********
Primary Recipe is as follows:
5 gallons Apple Juice
4 lbs. Frozen Blueberries
1.5 cups Craisins
2 lbs Light Brown Sugar
2 Cans Apple Juice Concentrate
1 pkt 71b yeast, rehydrated
When racking 4 750's worth was siphoned off and bottled, the secondary additions were to add more blueberry flavor and aromatics and replace what was taken out.
added 5 pounds of blueberries
62oz of pure blueberry juice
1 gallon of apple juice
I am sure there are some things I could have done differently, but this is all just experimenting for me and I am having a good time with it. I know that many people suggest adding fruit in secondary to impart more fruit flavor, but I chose to do it this way to start. Due to the advice of a member, I started the blueberries in primary and will rack onto some more depending on color and taste in a month or so.
The airlock showed activity within a couple hours and today it is bubbling once every 5 seconds or so.
So, I just started this thread to keep updates on this, because at least for me, I didn't see many threads on blueberry cider, some on meads and wines, but not cider. But any suggestions any of the more seasoned members have are and will always be very welcome.
Here is a pic showing it bubbling away in my bathroom on a towel to keep it from the cool floor, but the room itself is kept between 65 and 70.
And here is a picture of my "brewing closet" which contains my JAOM, my spiced cider, my cyser, and my pomegranate mead.
