So, where did the whole can thing come from? The answer is in the way the cranberries are harvested. Americans consume very little of the total cranberry crop as fresh fruit. In 2013, only 5 percent of the cranberries produced were sold as fruit. That means 95 percent of it was consumed as a processed product, like juice, jams, and of course, sauce. And the berries used for sauce and juice are harvested wet.
