I used to think so until I read that experienced bartenders like to let the juice sit for 3-4 hours after squeezing for best flavor. A test by Cooks Illustrated verified that letting the freshly squeezed juice sit, covered, in the fridge for 4 hours (but not much longer) gave a “more mellow yet complex flavor.” Doesn’t work with other citrus juices, however. In fact, orange juice is best squeezed just before serving for best flavor because sitting for even a few hours can permit the formation of limonin, a harmless but bitter-tasting compound.
