I keg my ciders and have found absolutely no difference whether using a secondary of only primary. All of my ciders are made with processed apple juice that is clear from the start.
I don’t use a secondary either. My cider is also made from processed apple juice and is a little cloudy when I bottle, but clears after I pasteurize and cold crash for a few days. While I’m not the most experienced at making ciders, I can tell you my ciders are crystal clear when finished without the use of a secondary vessel of any kind.
I ended up using 2 gallons of locally-pressed Gravenstein apple juice (and used Fresco yeast) but did not do a secondary. I was like “ehhhhhhh, who is this for, except me” and I’m now using floating dip tubes in my kegs. It turned out the cider cleared up quite a bit anyway. It was absolutely delicious and very pretty as well. I loved the combo of Gravenstein flavor, dryness, and carbonation, and did not backsweeten.
I meant to get Pink Lady cider to make a subsequent (and possibly even prettier) batch, but I was traveling for work and then evacuating due to the Kincade fire and then catching up afterwards… gather ye ciders why you may! The orchard I purchased this from freezes its pressings so I may yet be able to make another batch this fall.
After brewing beer for over a decade, my overall experience of making cider was “wait, I’m done?”
