Nestos Capers are a product of Nestos Foods, a company established in 1978 in Northern Greece. The company is located in the valley of the Nestos river and processes agricultural products shortly after harvest to preserve their freshness and flavor. The capers are hand-picked flower buds pickled in a vinegar brine. They are a key ingredient in Mediterranean cuisine and are described as having a salty-sour taste with a subtle lemony-olive flavor
