California grape growers are shipping at or close to a record pace this summer.

For three weeks in a row in August, more than 4 million boxes per week shipped from the Golden State, according to a news release from the Fresno-based California Table Grape Commission.

“The crop is moving at what could be a record-setting pace,” Kathleen Nave, president of the commission, said in the release.

According to the U.S. Department of Agriculture, more than 28 million boxes of California table grapes have shipped through Aug. 23, 3% ahead of last year at the same time.

In 2012, for the first time ever, more than 100 million boxes of fresh-market grapes shipped from California.

Consumers’ increased focus on nutrition is helping to drive category growth, Nave said.

“Shoppers are becoming more health conscious about the food they buy for themselves and their families. As one of the top-selling fruit categories, grapes are a good fit for today’s shopper.”
