ARBEQUINA -Spanish light brown olives in brine - This variety of olive represents one the best regions in Spain in which the finest table-oils are produced: Catalonia (Arbequina). The best olives are carefully selected from the tree and are placed in water and salt for a minimum period of three months. Finally, they are rinsed with plenty of water and are bottled with fresh water, and salt. An effervescent reaction may occur when opening. This reaction is normal since the olives are completely natural (no preservatives or chemical used).
