Who wouldn’t be all ears, if someone promised California raisin growers that overhead and open gable trellising systems would produce 3 to 5 tons or more raisins per acre that never touched the ground for sun drying?

This is an open gable vineyard harvested by a mechanical harvester.
2. Raisins on Continuous Trays.jpg
Field dried raisins evolved to this continuous tray drying. Canes are cut to begin the drying process on the vine and them when the fruit has dried sufficiently, mechanical wine grape harvesters shake the partially dried fruit from the vine and deposits it on continuous paper trays to finish drying.
3. Traditonal Raisin Drying.jpg
The traditional way to make raisins is to lay them on paper trays in the middle of the row.

These four DOV raisin growers shared their experiences on growing dried-on-the-vine raisins at a San Joaquin Valley Viticultural Technical Group meeting.
