Nicola Twilley reveals how orange juice is available all year:
To engineer a consistent supply of a highly perishable product, Big Juice (Tropicana, Florida’s Natural, and their ilk) pasteurize, de-oil, and then strip the oxygen from their OJ before chilling it to 32°F and pumping it into million-gallon, refrigerated, epoxy resin-lined, carbon steel, aseptic storage tanks. There, according to Alissa Hamilton, author of Squeezed: What You Don’t Know About Orange Juice, it often sits for as long as a year, from processing season to processing season, before being rejuvenated with the addition of specially formulated flavor packs (to ensure each brand maintains its own trademark taste), and shipped to a distribution center in Jersey City on the refrigerated box cars of the CSX "juice express," a favorite of East Coast train spotters.
