The first set of crops I harvested were all referred to as "Fresh". I don't recall this system being present in previous games, so I'm not sure how it works. I'm assuming the effect expires after a few days, and that it could extended if I bought a fridge, but I don't have any data on it (I'm just guessing). I'm also curious if it's possible to produce to go rotten as well, and if so, what effect that has.
What are the benefits of fresh produce? How long does it last? Can produce eventually go rotten as well?
