Castanheira Natural Cured Olives from the Douro region are traditionally prepared using time-honoured methods that highlight the olive’s deep, natural flavour. Rich and slightly robust, these olives have a firm bite and a beautifully complex profile that develops through natural curing rather than brining alone. This generous 3 kg format is ideal for frequent use, entertaining, or professional kitchens—offering authentic Portuguese quality in a larger, pantry-staple size.
