Regular orange juice has a peak flavor profile of under three hours. Lemon, and lime juices the flavor improves for around six hours, then subsides over the next 6-12 hours. Grapefruit juice improves for up to 3 days to two weeks. All this is chilled juices.
Clarified citrus juices are much more stable than unclarified. They don’t have the full flavor profile, as one would expect since you are removing a large portion of what makes up the flavors. But kept chilled can be stable for several weeks at home, or even many months to a year in the case of commercial OJ producers.
The unused portions can end up being great, or horrible. With citrus juices they can be bitter and strong. I have used them as an added flavor boost when making marmalades. In other juices, the solids can be wonderful. I make a fresh quince syrup and the solids are basically Membrillo.
