In its earliest form, Monterey Jack was made by 18th-century
Franciscan friars of
Monterey,
Alta California. In the 19th century, various individuals contributed to the production and commercialization of this cheese. Notably, Doña Juana Cota de Boronda began making and selling
Queso del País (
Spanish for "country cheese") in Monterey to support her family after her husband became incapacitated. She utilized a handmade jack to press the curds, which may have influenced the cheese's eventual name. California land speculator and businessman
David Jacks sold the cheese commercially. He produced a mild white cheese that came to be known
eponymously as "Jacks' Cheese" and eventually "Monterey Jack". Other ranchers in the area likewise produced the cheese, among them Andrew Molera, who built a successful dairy operation in
Big Sur and whose Monterey Jack was especially well regarded. ==Aging==
