Grapefruit Tomato Review & Photos

Rate this

📌 Quick Summary (TL;DR): Grapefruit

  • 🌍 Origin: A highly regarded commercial/heirloom variety. The original “true” Grapefruit is a stunning bi-color tomato (yellow/orange with a red blush and red marbling inside).
  • 🌿 Plant Habit: Indeterminate. A very tall and powerful plant, easily reaching 6.5–8 ft (2–2.4 m) in a greenhouse. It can be grown outdoors but prefers a lot of sunlight and does not tolerate shading well.
  • 🍅 Fruit Characteristics: Large to giant bi-color beefsteaks. They often weigh between 10.5 oz to 1.5 lbs+ (300–700 g). Note: See the forum debate below regarding pink and dark mutations!
  • ⏳ Maturity: Mid-season to mid-late.
  • 👅 Flavor: Widely considered by Russian growers to be one of the absolute best-tasting bi-colors. It is incredibly sweet, juicy, and fruity. It avoids the blandness that sometimes plagues other yellow/red bi-colors.

I was surprised to see that this variety isn’t in the catalog yet. Mine are from Marinochka in Sochi – thank you so much!!! 🌺 🌺 🌺

Grapefruit is an indet, growing in the greenhouse, currently about 7.8 ft (240 cm) tall. It was one of the first to set fruit and it sets trusses with almost no dropped blossoms. I’d be hard-pressed to guess the total weight currently on the bush 😲, but it’s a LOT. Can’t taste them just yet, they should be ripe in a few days. If the flavor is worthy, this tomato will definitely become a permanent resident in my garden.

I also have Grapefruit from Marina in Sochi. In the greenhouse, the height is 5.2 ft (160 cm). The yield, of course, is lower than Marisha’s – only 8 fruits total, but they are all roughly the same weight, and the ones at the top are probably even bigger. The first one weighed 12.7 oz (360 g). I really liked the taste. It has already secured a spot on my planting list for next year.

What a beauty! Mine is just about to ripen, I really want to pick a fully ripe one right off the vine, but since there are so many fruits, the ripening is delayed. Maybe I should have picked the first truss early, as usual, so it wouldn’t slow down the rest of them.

My Grapefruit, seeds from Redko. Indet, currently 5 ft (1.5 m). Very delicious 😘, but the yield is low. I’ll grow it again and try to tame it.

And here is my Grapefruit! Large, sweet, and very tasty! Seeds from Marina in Sochi. I also had a Grapefruit from Lesya in Kryzhopol. They are almost identical. But Marina’s ripened faster, so it made it into the photo album first. 🙂 And I happily devoured Lesya’s and gave the rest to the kids.

Very productive – I’m surprised myself… I’ll get about 11 lbs (5 kg) from a single bush, which is a lot for me. The plant is very vigorous; initially, I pruned it to 2 stems, but now it looks like it’s growing into four… late season, large fruits, nice tang/acidity, juicy. Huge thanks to Toma-Drakonka for the seeds! 🌺

I’m growing this variety for the third year. Originally, seeds from Popenko. It does well both outdoors and in the greenhouse. Yield is average. I test a lot of bi-colors every year, but nothing has beaten this one in flavor yet.

Planted Grapefruit for the first time in 2015. In the greenhouse, it turned out to be one of the largest, although it was a bit late and didn’t have time to show its full potential. Here is one of the beauties:

Loved both the taste and the size!

The first fruits were on the smaller side, but on the second and third trusses – it was just a sight to behold!

Hello! Outdoors my Grapefruit was a little over a meter. I don’t remember exactly, but I remember it wasn’t tall, maybe around 4–4.2 ft (1.20–1.30 m).

I also love this variety. To me, it’s the tastiest. There is a faint, barely noticeable hint of tang/acidity in it, which makes it impossible to confuse with any other variety. Planted several bushes this year, and I told my family that the Grapefruit tomatoes are mine alone 😋

This year, Grapefruit surprised and delighted me even more. Its fruits were the largest. Here is the record weight for this season:

The best harvest was on a bush that grew freely in the grape greenhouse. Grew to 2 stems, was about 6.5 ft (2 m) tall. On the upper trusses, the tomatoes were even larger than on the lower ones. I picked the last fruits in October, we just recently ate the last one.

The taste is very good! And it’s a beauty 👍

I grew it again from my saved seeds and realized that this variety cannot tolerate even the slightest shading – it grew in the middle of the central bed, and the yield and fruit size are significantly inferior to last year (last year it grew right near the entrance door).

Planted it for the second year and will continue to plant it. Last year it was a bit late, but this year it was one of the first, though last year it was outdoors and this year in a Stabilen film greenhouse. Mine wasn’t as huge as Ilya’s, it was around 10.5 oz (300 g), sweet.

Yes, neither the color nor the shape looks like Grapefruit. It’s an off-type (wrong seeds).

But here are mine. Very tasty, productive, beautiful!!!

The tastiest tomato! Perfect flavor! Just the right amount of sweetness and acidity, a very balanced dessert flavor. All the tomatoes are uniform, large, and beautiful. Basically, whether for a salad or as a gift – it’s universal! I cut this tomato in the greenhouse today (the greenhouse has been wide open all season), this isn’t the first or second truss, it was at chest height.

Gorgeous cross-section. I’ve read that this variety is the sweetest of all the bi-colors. I’m sitting here licking my lips.. Could you tell me where the thread is on this forum for trading seeds for 2020? (I’m new to this forum, but I’ve been growing tomatoes for a long time).

I really want Grapefruit, I would gladly share seeds in return.

It tastes amazing too, though I didn’t plant it this year, was testing out new varieties. But I should have seeds from previous years, I’ll check…

Grew it outdoors in 2019. Natalya Borisovna sent me the seeds. Outdoors the bush was just over 5 ft (1.5 m). My attempts to prune it to two stems completely failed, so it ended up with either 3, 4, or 5 stems. Productive, mid-season. The fruits are very beautiful, but whether it was just a bad year for bi-colors, my hands doing something wrong, or the variety just isn’t for me, there was no special sweetness in Grapefruit this year. Wouldn’t say it was disgusting, but it wasn’t amazing either.

So large and what’s interesting… I noticed that everyone’s Grapefruits look different both externally and in cross-section…

In this thread, everyone’s true-to-type Grapefruits are the same, the shape only differs depending on whether they came from fused blossoms (megablooms) or single blossoms. Single blossoms are more rounded. Ilya and Shevyachok have off-types.

P.S. Please don’t clutter the thread with messages unrelated to the discussion of the variety.

My variety is called Pink Grapefruit, seeds from Redko. Picked the first fruit, the flavor is a 4 out of 5 so far, good tomato taste, balanced, very decent for the first fruit. I like that it doesn’t have excessive juiciness.

I have been planting Pink Grapefruit from Redko for many years. I like the variety, I plant several bushes. In 2020, among these bushes, one bush appeared with bi-color fruits. At first I thought I made a mistake. But looking closely, it became clear that the variety had segregated (mutated) and very successfully. The fruit shape and structure, plant habit, and the wide leaf were identical. And in 2021, it gave me another segregation—this time into dark/black fruits. The color is exactly like Black with a Beak from Borisovna. But thanks to its wide leaf, I don’t have to give it the most prime sunny spots in the greenhouse. Now I plant all three of these varieties and I love them very much. All three have that dense, delicious, marmalade-like flesh that I love. The smaller ones go into canning jars. They turn out firm, not fibrous.

I actually wrote to V.V. Redko about this variety. She replied that originally this variety was supposed to be a bi-color, but it grew pink for her. So she just named it Pink Grapefruit.

Irina, I’m indifferent to bi-colors because they just don’t turn out well in my growing conditions. But your dark/black one really caught my eye. Can I hit you up in the fall for some seeds? I have plenty to offer for a trade.

👨‍🌾 Editor’s Note on Mutations & “Off-Types”:
The thread above is a fantastic look into the wild world of heirloom tomato genetics! You’ll notice several growers complaining about getting solid red, pink, or even dark/black tomatoes from seeds labeled “Grapefruit”. In the gardening world, this is called an off-type.
This happens for two main reasons: either a simple accidental cross-pollination by a bee in the seed grower’s garden, or genetic segregation (where a supposedly stable heirloom suddenly reverts to the traits of one of its ancient parent plants).
As user Irina points out at the end of the thread, this isn’t always a bad thing! A Russian seed seller noticed her bi-color Grapefruit mutated into a solid pink tomato with the exact same amazing flavor and leaf type. She stabilized it, named it “Pink Grapefruit”, and it became a hit. Then, it mutated again into a dark/black tomato! This is exactly how many of our favorite modern heirlooms were originally discovered.
