Since 2008 the ASU Campus Harvest has organized the sour orange harvest on the university's Tempe campus. The harvest lasts over three days as more than 100 volunteers collect over 6 tons, or 12,000 pounds of oranges, from across the campus.
The oranges are then transported to Sun Orchard juicery in Tempe, where they are juiced and bottled to be used for cooking and making "devil ade" — which is served as part of ASU's Aramark campus dining rooms.
