La Serenísima Milk

La Serenísima is the leading dairy brand in Argentina, widely recognized for its high-quality milk, yogurt, and cheese products. Founded in 1929 by Antonino Mastellone in General Rodríguez, Buenos Aires, the brand began as a small cheese factory and grew into a pillar of the Argentine food industry.

Behind its operations is Mastellone Hermanos S.A., which maintains extensive production and collection networks across the country. In 2015, the multinational food giant Arcor, in partnership with Danone, acquired a significant stake in Mastellone Hermanos, eventually becoming the primary controlling interest. This strategic ownership ensures that while the brand remains quintessentially Argentine in heritage and production, it possesses the global reach and financial backing of one of Latin America's largest food groups.
