Farming technology keeps changing and becoming more mechanized in this era of modernization and efficiency. Raisins used to be created by cutting then drying bunches of grapes on paper trays laid on the ground. Now they can dry them on the vine. A trellis roof of wires allows vines to grow on top while the bunches of grapes hang below, hence, the "ceiling of grapes". When the sugar content is right, the vines are cut to stop the nutrients and water from going to the bunches while they dry in the air. Then a machine comes along and collects the finished product. Similar to a grape arbor, this giant trellis covers acres and acres of vines. It's a quicker and cleaner way to make raisins.
