These small tomatoes come from a local variety produced on the islands of Santorini, Thirasia, Palea Kameni, Nea Kameni, Aspro, Christiani, and Askania in the Cyclades in the southern Aegean Sea. The production, treatment, and processing of these tomatos must be carried out exclusively within this area in order to avoid deterioration in the quality of this fragile fruit.
Tomataki Santorinis is a deep red color and has a firm, not particularly moist flesh with a high seed content. These tomatoes owe their distinctive characteristics to the climatic conditions and the limey, alkaline soils of the area. It has high levels of acidity and, due to the alkaline soil, a high sugar level when ripe.
