The original name of the tomato variety sounds like Red Charcoal, but in our country it is called Red Coal. This name is associated with the non-standard color of vegetables, which have an unusual combination of black and red. During the ripening period, their appearance resembles smoldering coals, since the tomatoes have a rich red color below and a black-purple hue on top.

The description of the variety classifies it as a medium indeterminate species. Tall bushes can grow up to 1.8 meters and, due to this feature, need staking and pinching. The shoots are characterized by good stem thickness, power and resistance to external factors.
The plant is capable of showing high yield values when grown in open ground and in greenhouse conditions. When planted in open ground, the shoots are characterized by smaller growth, the height of the shoots reaches from 1.2 to 1.3 meters. It is recommended to grow bushes with two main stems.
The characteristics of the Stone Coal variety indicate the possibility of using the fruits fresh and for canning. Thanks to the unusual color, salads from Red Coal tomatoes acquire a special piquancy and unusual appearance. Breeders consider resistance to most varieties of tomato diseases to be an advantage of the variety.
Features of fruiting
The fruits are round in shape and have a smooth surface. The average weight of one vegetable is from 100 to 200 grams. Reviews from gardeners indicate the presence of a delicate aroma with subtle notes of fruity aroma.
The process of fruit ripening is interesting. At first they acquire a reddish tint, then in the area of the stalk the vegetables change color to a bluish tint, and towards the end of the fruiting period they acquire a coal black color.
The vegetable pulp is dense, deep red in color with a small number of seeds. The advantage of tomatoes is their high content of a substance such as anthocyanin, which has a beneficial effect on the functioning of the cardiac and vascular systems and reduces the risk of cancer. It is thanks to the high content of this element that vegetables acquire an unusual color.
The plant is characterized by high yields and with proper agricultural technology, up to 5.5 kg of tomatoes can be harvested from one plant bush. On average, one cluster of adult shoots contains 5 vegetables.Brushes with a lot of vegetables may need additional tying.
