As an older guy, I would say that the " The Longer you Wait, Sweeter is the Reward" could apply to so many things.
Fermentation comes to mind. Because cider needs to wait so it's get sweeter.
My guess is sweet sweet fermented product.
Pickles, Kraut, Kim Chi.....
The longer I wait.... The sweeter the reward.
