The procedure of apple juice is quite simple. They fall into a bowl with water and ...

... get cleaned without any chemicals, then they are pressed between 4 metal rolls that get slimmer every time. What makes the juice storable and keeps it from fermenting is a big canister that heats it up to 80 degrees. Then it immediately gets poured into plastic bags and closed with a tap. It can be stored for 2 or more years of you can wait that long 😁

Sadly I couldn't document the whole thing because the workers didn't want to be in the picture.
