SANTA ROSA, Calif. – La Tortilla Factory is closing its Santa Rosa plant and moving 1,600 miles across the country to the heartland. Flagship Food Group, which owns a large stake in La Tortilla Factory, told SFGATE that they’re moving tortilla operations to Moundridge, Kansas, after they were unable to purchase the property they’ve been on since 1977. The Santa Rosa factory is expected to close on March 31.
