The Secret of Black Tomatoes - Why Grow Them and How to Tell When They're Ripe
At first glance, they look a bit like a forgotten piece of fruit - a dark skin, sometimes purple-black, other times with hints of dark green or brown. Yet, black tomatoes are gaining more popularity among gardeners and gourmets. Their exceptional appearance is not the only thing that sets them apart from classic red tomatoes. They have an intense flavor, higher antioxidant content, and even a beginner can grow them.
But how do you actually know when a black tomato is ripe? And what are the ideal conditions for its cultivation? Although black tomatoes are not a novelty of recent years - their origins trace back to South America - their popularity in Europe and the Czech Republic is growing slowly but surely.
What are black tomatoes and why are they dark?
The dark color of black tomatoes is mainly due to anthocyanins, natural pigments commonly found in blueberries, red cabbage, or grape wine. However, they are rather rare in tomatoes. Thanks to them, the fruits have a darker shade, ranging from dark purple to almost black. But color is not just an aesthetic feature - anthocyanins have strong antioxidant properties, and thus black varieties often surpass regular tomatoes in nutritional values.
Commonly grown varieties include Indigo Rose, Black Cherry, or Kumato. Each has a slightly different taste - some are sweeter, others spicier, but it can always be said that black tomatoes have a more complex and deeper flavor profile than their red counterparts.
Growing Black Tomatoes - Nothing to Fear
Black varieties are not more demanding than classic tomatoes. The key to success is sun, regular watering, and quality soil. Ideally, they should have access to sunlight for at least 6 to 8 hours a day. They also appreciate well-draining soil rich in humus. If you decide to pre-cultivate seedlings, start in March or April. You can plant the seedlings outside after the last frost, around mid-May.
Interestingly, some black varieties have greater resistance to diseases and pests. For example, Indigo Rose was bred specifically to increase resistance to blight. Thanks to this, black tomatoes can be grown without chemical protection, which is appreciated especially by those striving for a more ecological way of cultivation.
One of the advantages of black tomatoes is also their storability. While some red varieties quickly spoil, darker fruits often last longer - also due to their firmer skin. The skin can be a bit tougher, but it also protects the flesh from drying out.
How to Tell if a Black Tomato is Ripe?
If you're used to harvesting tomatoes based on their red color, black ones will present a bit of a challenge. The dark skin is misleading - it often looks ripe even when the fruit still needs a few days to mature. Conversely, it may seem unripe even when it's at its peak flavor. So, how to tell?
The best guide is a combination of color, touch, and scent. A ripe black tomato has a rich dark color, often with a hint of purple or reddish-brown. Green tones near the stem are usually a sign that the fruit is still ripening. However, if the rest of the tomato feels softer to the touch and slightly yields when pressed, it is probably ready for harvest.
Another sign is the scent. A ripe tomato - even a black one - emits a characteristic sweet, sometimes slightly earthy aroma. If you smell it and sense a fresh, tomato scent, it's a good sign. If you don't smell anything, wait a little longer.
An example can be the experience of Mrs. Hana from Vysočina, who has been growing black tomatoes for several years: "I used to pick them too early because they already looked dark. But they were hard and tasteless. Now I wait until the color stabilizes and they start to soften. Sometimes it's just a few extra days, but the difference in flavor is huge."
Where to Use Black Tomatoes?
Besides the garden, black tomatoes have found their way into gastronomic establishments, where they are valued not only for their appearance but also for their taste. They are great for salads, where their contrasting color stands out, but also for baking, grilling, or sandwiches.
They are also fantastic raw - just drizzle with quality olive oil, add sea salt, and a few basil leaves. Due to their lower water content and higher sugar concentration, they are often used in homemade salsas and sauces - the resulting taste is sweeter, fuller, and deeper.
Given their higher content of antioxidants, vitamin C, and other micronutrients, black tomatoes are considered a superfood, which can easily be incorporated into a daily diet. Moreover, they do not contain any exotic substances - everything is the result of natural selection or crossbreeding, with no genetic modification.

Why Are Black Tomatoes Still Not Widely Known?
One reason why black tomatoes aren't more widespread is consumer conservatism. Many still associate tomatoes with the red color and consider the dark fruit overripe or even spoiled. Additionally, in regular supermarkets, these varieties are rather rare - often sold in premium lines or at farmers' markets.
But the situation is changing. People are increasingly seeking exceptional flavors, alternatives to industrially grown crops, and foods with higher nutritional value. And black tomatoes meet all these demands. They also fit into the trend of sustainable and ecological cultivation, which is crucial for many home growers.
Although the term "black tomato" might evoke exoticism or something unnatural, the truth is quite the opposite. It's a return to a richer palette of flavors, colors, and nutritional benefits that modern breeding has often suppressed in favor of appearance and shelf life.
Try Growing Your Own
Unlike some other specialties, growing black tomatoes is no science. Choose seeds from a reliable supplier, pre-cultivate seedlings, give them sun and a bit of care - and you'll be rewarded with tasty and healthy fruits that will not only enrich your diet but also your garden.
You might be surprised how many people will ask you what kind of strange fruit it is when you show them your own harvest. And perhaps even your neighbor, a long-time grower of classic tomatoes, will decide to try it next year.
As the famous American tomato breeder Tom Wagner says: "A tomato is like a canvas - and color is just the beginning of the story." Black tomatoes will convince you of this with the first bite.
