El Caserío Quesitos

El Caserío is an iconic Spanish brand specialized in processed cheese, best known for its triangular 'quesitos'. The brand was founded in 1931 by Lorenzo Valcárcel in Mahón, Menorca. It became a household name in Spain, famously associated with the slogan 'De El Caserío, me fío' (From El Caserío, I trust).

While the brand maintains deep Spanish roots and a significant production facility in Namur, Belgium (which supplies much of the European market) and formerly in Menorca, its ownership has transitioned through major international conglomerates. Today, the brand is owned by Mondelez International, the American multinational food and beverage giant. Most 'quesitos' sold in Spain are produced in European facilities optimized for high-volume dairy processing.
