If you live in apple country, you have a wonderful resource readily available for pre- and post-TEOTWAWKI. All it takes is some up front costs for equipment, and your labor and desire. The process is simple. I'm speaking of producing fresh apple cider for immediate enjoyment or trade, and hard cider for delayed enjoyment, stockpiling, or trade. Thus, you can easily acquire a valuable skill for post-WTSHTF. A nice thing is you can gradually ramp up your expense and involvement.
You can:Buy the fermenting equipment and use purchased fresh unpasteurized sweet cider, skipping the expensive apple crusher and press and all the hard work Buy all the equipment and use purchased apples Go all-in like we did, buying all the junk and picking our own apples
[Be aware that if you buy apples or sweet cider, even from a local farm, you will probably be getting traces of fungicides and pesticides. But no doubt the fruit will be big and beautiful.]
