Heat of Burning Coals (Zhar Goryashchie Ugli) Tomato Review

Rate this

📌 Quick Summary (TL;DR): Zhar Goryashchie Ugli (Heat of Burning Coals)

  • 🌍 Origin: A Russian heirloom variety. The name translates to “Heat of Burning Coals” or simply “Glowing Coals”. (Note: Do not confuse with “Zhar-Ugli” by Siberian Garden, which is a purple anthocyanin variety).
  • 🌿 Plant Habit: Indeterminate (tall), but growth height varies greatly by region. Outdoors it can stay around 3.6-5 ft (1.1-1.5 m), but in a greenhouse, it easily reaches 6.5 ft (2 m).
  • 🍅 Fruit Characteristics: Large, bright red, oblate beefsteaks. Average weight is around 7-12 oz (200-350 g). The skin is relatively thin, which makes them tender but prone to splitting in heavy rain.
  • 👅 Flavor: The classic “old-fashioned” tomato taste. It is sweet, juicy, and very meaty, with a pleasant, slight acidic tang.
  • ⚠️ Grower Warnings: Prone to fruit cracking (splitting) if watered inconsistently or after heavy rains. Can also suffer from blossom drop during extreme heat waves.

Zhar – Goryashchie Ugli. Tanya (Tanika) shared the seeds with me. The taste has a nice little tang, I’d rate it 4.5 out of 5. The variety is mid-early, indeterminate, 5.2 ft (1.6 m) tall. A very vigorous bush. I grew 2 plants outdoors in the open ground. Unfortunately, I left my scale at the dacha, so I don’t know the exact weight.

I really liked the variety 👍. My seeds were from Ruslan Sirotin. The flavor is very pleasant, a sweet-and-sour velvety taste. Meaty and juicy. Outdoors, my plants only reached 3.6 ft (1.1 m). It sets fruit incredibly well. If it hadn’t frozen almost to death in the spring, I definitely would have harvested a full bucket per plant 😳

My average tomato weight was 8.4 oz (238 g). The largest was 12.3 oz (348 g). You have to admit, for such an anomalously cold and bad year in the Urals, the result is not bad at all. I’m definitely keeping this variety on my grow list. It does have one small sin, though – it’s prone to cracking. But then again, we had a ridiculous amount of rain this year.

Mine were probably from Tanika too. I loved the variety. Very large fruits, high yield. Grew outdoors, pruned to 2 main stems.

Just clarifying for accuracy. If anyone is wondering, I bought my Zhar Goryashchie Ugli seeds from Ruslan Sirotin. It looks exactly like Tamara’s (Drakonka’s) in the photos.

Tamarochka shared her seeds with me too 🎩 Only mine wasn’t mid-early, it acted more like a mid-late variety. It took a long time to get going, and then, completely unexpectedly, it set a massive amount of rather large tomatoes. A very pleasant surprise! The bush was about 6 ft (1.8 m) tall 👍

Svetochka (Svetlyachok-plus) shared seeds of this variety with me, for which I am hugely grateful! It was early, productive, and I loved the flavor – tender, sweet, with a barely noticeable tang. It had only one flaw – it was prone to cracking. Planning to grow it again in 2016.

This variety showed a tendency to crack for me too, but at the same time, I absolutely loved its excellent taste and yield. In the greenhouse, it grew to about 6.5 ft (2 meters) tall. Sweet fruits.

I grew one bush. It was nearly 6.5 ft (2 m) tall, pruned to a single stem. It turned out very productive and large-fruited, I even had to tie some of the trusses to the neighboring bush for extra support. Loved the taste, juicy, sweet, with thin skin. Seeds from Ilya Korolev (ilja).

Hey everyone! I’m growing this variety again, not just 3 bushes this time, but more: it’s a very worthy variety! If it didn’t suffer from blossom drop in the extreme heat (so far, only De Barao has proven to be bulletproof against both heat and diseases for me), it would be absolutely priceless!

I got my seeds from Ilya Korolev, here is his description:

Tall (6.5 ft / 2 meters), productive mid-season tomato variety. Fruits are large, oblate, red, juicy, and meaty. Excellent taste, sweet.

Another absolutely magnificent tomato. Just blazing large fruits on a tall, vigorous bush. Very beautiful! It completely justifies its name. Early. Very tasty! Sweet with a slight tang. However, I didn’t slice it into salads. I tried it once with cucumbers, onions, and garlic, and I just couldn’t eat it. The flavor combo was off, it was too sweet to pair with raw onions and garlic. But paired with quick-pickled (lightly salted) cucumbers, it’s quite good. And it’s even better just eaten on its own.

The color rendering on the photos with the scale is wrong. I had to artificially brighten the photo so you could read the weight display. The true color is visible in the photos on the bush and on the table.

I’m planting this variety for the 2nd year because I really liked both the yield and the taste. But last year the tomatoes were large and extra-large, whereas this year they didn’t size up as much. The taste, however, remained excellent.

An excellent variety, a relatively short indet, early season, grew in the greenhouse pruned to 2 main stems, very productive 👋 The tomatoes are red, excellent taste, the weight for me reached up to 12.3 oz (350 g).

Seeds are from Masha @Murka 🙏

I’ll add – it grew and set fruit perfectly pruned to 2 stems in my eastern garden bed. It is prone to cracking, though.

Zhenya @Jina, thank you! 🙏

Girls, I bought seeds of this variety, but the picture on the packet shows anthocyanin (purple) shoulders. The packet is from Siberian Garden (SibSad). But all of your photos just show regular red tomatoes. Did I buy the wrong thing? In the seedling stage, it was the only one that sprouted with a purple stem.

You bought a different variety. Siberian Garden’s packet says “Zhar-Ugli”, and this thread is about the variety “Zhar Goryashchie Ugli”. These are two completely different varieties with similar names.

My Zhar Goryashchie Ugli is from Tatyana @Tanika.

I’ve had the seeds sitting around for a long time, but only planted them this year. Worthy, large fruits, but the variety didn’t reach its full potential for me on the first try, it only yielded about 7.7 lbs (3.5 kg) per plant.

I’ll analyze my mistakes, and hopefully, the result will be better next time, but for now, here it is:

👨‍🌾 Editor’s Notes:

  • Naming Confusion (“Zhar-Ugli” vs “Zhar Goryashchie Ugli”): As highlighted in the discussion between Viktoria and Tatyana, the Russian commercial seed market can be a minefield of confusing names. The variety discussed here is a classic, large red beefsteak heirloom. However, the commercial seed company Siberian Garden (SibSad) sells a completely different, genetically distinct variety called “Zhar-Ugli” (Glowing Coals). SibSad’s version is an anthocyanin (purple-shouldered) novelty tomato. If you are trading seeds, make sure you know which one you have!
  • Blossom Drop in Heat: Several growers noted that this variety can drop its blossoms during intense summer heat waves. When temperatures exceed 90°F (32°C) during the day or fail to drop below 70°F (21°C) at night, tomato pollen becomes sterile. The plant aborts the unpollinated flowers, causing a gap in the harvest.
