California's table grape industry shipped nearly 100 million boxes of grapes during the 2010 season, according to the Fresno-based California Table Grape Commission.
Of the 97.7 million 19-pound box equivalents, 37.4 million were exported to more than 62 countries.
The remainder were sold domestically.
The total value of the crop was $1.3 billion, with about half of that coming from exports, according to the U.S. Department of Agriculture.
The table grape season begins in May and runs through January.
The leading varieties based on volume are Crimson Seedless, Flame Seedless, Red globe and Thompson Seedless.
