Água de São Martinho Spring Water

Água de São Martinho is a Portuguese spring water brand sourced from the Caldas de São Martinho region in Maceira, Alcobaça. The water is bottled directly at the source, ensuring its natural mineral properties remain intact from the aquifer to the consumer.

The brand is owned and operated by the original company Sociedade das Águas de São Martinho, S.A., which has deep roots in the Portuguese beverage industry. As a local producer, the manufacturing is strictly contained within Portugal, serving both the domestic market and export sectors. The ownership remains within the Portuguese business landscape, maintaining a heritage focused on national natural resources.
