We made and froze our own cider when I was a teenager. I built a press in woodshop class. It was a lot of work but the cider was great. We used to freeze it.
Later I made 250 gallons a week at the orchard I worked at. I recall it sold for $3.50 a gallon at that time and we could use windfalls.
Now with the law against using windfalls and the issue of being UV or heat treated, most orchards around here do not even offer cider anymore. If they do it is usually filtered (Yuck) and tastes as bad as the so called apple juice sold in the grocery stores in glass bottles.
I finally found two sources near me that still produce good cider that is not filtered. One does a UV treatment and the other just has a warning label on the product that is may be harmful to
children and elderly as not pasteurized. One place sells it for $10/gallon and the other for $9.50 a gallon. I always stock up and freeze it to enjoy the rest of the year.
Not sure what Zaiger cider puts in for preservatives, but I have tried some at my local supermarket. Surprised to see on the label that it keeps for 60 days? It was just ok but I have not tried the version they are making with 100% Honeycrisp. Perhaps I should but I was concerned it would be far too sweet for my taste if not other blend of apples with it.
