Giant Green Cerignola olives are a popular type of olive originating from the Cerignola region in Italy. These olives are known for their large size, meaty texture, and mild flavour. They are often sold in brine, a solution of salt and water, which helps to preserve their freshness and flavour. While packaging olives in brine, it must be ensured to choose high-quality olives that have been properly preserved. The brine should not be too salty or acidic, as this can affect the taste of the olives. The olives should be plump and firm, with a shiny and uniform appearance.
