Giumarra Vineyards is a family-owned and operated grower, packer and shipper of premium California Table Grapes, headquartered in Edison, California. Our vineyards stretch from the southern end of the San Joaquin Valley to Ducor in Tulare County. Our California season starts in late June, and continues through November. Off season, we supply our retail and wholesale partners with quality grapes from our suppliers in Peru and Chile through our Wilmington, Delaware office, and from Mexico through the Giumarra Companies office in Nogales. Our breeding program creates and licenses the popular ARRA line of proprietary grape varieties, which are currently being planted and grown around the world.
