La Serenísima's extensive distribution network ensures that its products reach consumers nationwide efficiently.

Significant Events

A transformative event in La Serenísima's history occurred in 2018 when Arcor, a leading Argentine food company, acquired a controlling stake in Mastellone Hermanos S.A. This acquisition was a strategic move to optimize resources and enhance the company's competitive advantage in the industry.
