The company—which markets under such labels as Rex Goliath, Woodbridge by Robert Mondavi and Clos du Bois—said it was making the move because of increased demand for its brands and to create additional efficiencies with in-house and state-of-the-art technology, according to a news release.
The projects, in various stages of completion, will be finished by the end of the year.
The company also plans to hire 15-25 employees to accommodate the increased production.
In addition, it plans to purchase or lease more than 750 acres of additional land to develop in the Lodi delta area of San Joaquin County.
The cooler climate is suited to varietals, such as pinot noir, chardonnay and some cabernet sauvignon.
At its Gonzales winery, tank expansion will increase crushing capacity to 80,000 tons from 70,000 tons.
At the Turner Road Vintners winery in San Joaquin County, Constellation is adding 7,000 tons of crushing capacity and 1.5 million gallons of storage.
In addition, Constellation has installed a Tetra Pak bottling line at Turner Road and will add a bag-in-a-box line to its Mission Bell Winery in Madera County.
