In Greece, the Greek Islands, and other areas around the Mediterranean Sea, these delicious little small tomatoes are famous for their incredible flavor and aroma. Keep reading to learn more about Santorini tomatoes.

History of the Santorini Tomato

Regular tomatoes don’t always have a fascinating history, but the Santorini tomato certainly does. It all started in 1917 when the Russian revolution caused the shuttering of most of the country’s Orthodox churches.

At that time, the Greek volcanic island of Santorini suddenly had a new problem. Their biggest customer for the wine made by Greek Santorini monks was Russian churches. Realizing that they needed a new cash crop, the merchants turned to something unexpected: the Santorini tomato, which proved to be a lucrative venture.

Most experts believe that a Capuchin monastery abbot first brought cherry tomatoes to the Greek island as early as 1818. By the early 1900s, more than 20,000 acres of tomatoes were regularly harvested in Santorini, Greece. Since 2013, the Santorini tomato has had an official designation of origin and has been protected.

Characteristics of the Santorini Tomato

Santorini tomatoes are deep red in color and have flesh that is firm and not particularly moist.

Ripening Season

Santorini tomatoes ripen about 80 days after planting. Seeds germinate between five and ten days.

Tomato Qualities

These cherry tomatoes are small and the plants produce round flat fruit. Santorinis consistently remain deep red in color.

Experts say that cherry tomatoes from Santorini are the world’s richest tomato in lycopene, which gives the tomatoes a distinctive flavor.

Tomato Size

Santorinis are cherry tomatoes. They look like an average-sized cherry tomato and measure between five and six centimeters (about 1/3 of an inch), but the flavor is distinctly different.

Planting Zones

Santorini tomato plants thrive in USDA Hardiness Zone 11. You can try planting them in other areas of the country, but keep in mind that these cherry tomato plants thrive in a dry climate and can’t tolerate cold weather. Their minimum cold hardiness is +4.4 °C (40 °F) to +7.2 °C (50 °F).

Size and Spacing

Plants should be spaced about 20 inches apart (50 centimeters). Space your rows between 23 and 27 inches apart (60-70 centimeters).

Sow your seeds to a depth of five millimeters.


Santorini tomatoes are self-pollinating.

Plant Care

Santorinis are indeterminate tomatoes, which means that these plants are climbers. You will need to use stakes or a tomato cage for best results.

For best results, ensure that your tomato plants get six to eight hours of full sunlight daily.


The natural soil used to grow Santorini tomatoes is volcanic soil that contains no nitrogen. However, the soil in Santorini contains hygroscopic sodium, which means that the plants can absorb and trap moisture from the air.

This tomato was developed in alkaline soil that is limey. Keep in mind that Santorini is an island that is volcanic.


For tomato plants to thrive, they need to be planted in soil that is kept moist but never becomes fully saturated. After planting your tomato plants, water the plants every day for five days. Then, water tomatoes every two or three days, depending on how dry your climate is.

One thing that is helpful is that Santorini tomatoes do well in dryer conditions because of the way these plants were developed. In their natural habitat, they are actually grown with minimal water.

For all tomato plants, you’ll get the best results if you avoid overhead watering. Watering from the ground with soaker hoses helps reduce mold and disease.
