What La Serenísima does

La Serenísima is the consumer dairy brand of Mastellone Hermanos S.A., an Argentine dairy manufacturer founded in 1929 and headquartered at the Complejo Industrial Pascual Mastellone in General Rodríguez, Buenos Aires. The company produces a full dairy portfolio — fluid and functional milks, cheeses (Finlandia, Cremon, Reggianito, Gouda, Mozzarella, Port Salut, Brie and others), butter, cream, yoghurts, desserts, and dulce de leche — and serves primarily Argentine households, with a smaller food-service/industrial B2B channel and modest exports (10.61% of revenue, ~24,917 tonnes). It operates a vertically integrated model spanning 745 Brucellosis/Tuberculosis-free certified dairy farms, 139 milk-collection trucks, 11 production plants (5 classifying, 7 manufacturing per the 2017 report), and 13 distribution centers, processing ~4.07 million liters/day against ~6 million liters/day of receiving capacity.

The technology base is industrial dairy processing rather than software: raw-milk collection, farm certification, and manufacturing, supplemented by domain-specific protocols and packaging R&D. Differentiators include an IRAM-certified animal welfare management system (IRAM-ISO TS 34.700, 65+ control points and 25+ criteria per farm), the "Plan Más Leche" / "TamboMás" producer development programs, and sustainable packaging innovations such as 100% recyclable PET bottles with 20% post-consumer recycled content and a paperboard cheese cup reducing virgin plastic by 8%. The company also holds ISO 50001 energy management certification and reached 100% renewable energy operations by April 2026.

Revenue is generated through branded consumer dairy sales distributed across 63,340 domestic points of sale via major retail chains (Coto, Carrefour, Día, Disco, Jumbo, Vea, La Anónima) and last-mile platforms (Rappi, PedidosYa), plus a B2B ingredients channel and limited exports. Retail pricing is set by individual retailers and not publicly disclosed. The company is privately held; in March 2026 Grupo Arcor and Danone, through their Bagley Latinoamérica joint venture, agreed to acquire 100% of Mastellone Hermanos (subject to regulatory approval).
