For Anthony T. Rossi, an Italian immigrant who arrived in the U.S. with just $25, Florida orange juice proved to be liquid gold. Rossi founded Tropicana in Bradenton in 1947, delivering fresh-squeezed juice to local residents. In 1954, he found a way to pasteurize the juice and was soon shipping millions of gallons around the country. Today Tropicana, a division of PepsiCo since 1998, is the world’s largest producer of branded juice. And although citrus greening and changing tastes have reduced consumption in recent years, the average American still drinks more than three gallons of the sweet, sunny-hued beverage a year.
