Mazarini Tomato Reviews & Photos

Rate this

🍅 Quick take:

  • Plant habit: Indeterminate vine (up to 5.5 ft / 1.7m), characterized by a wispy, “dainty” foliage structure that doesn’t shade out neighboring plants.
  • Fruit & Yield: Produces large (10-33 oz / 300-950g), pinkish-crimson, meaty heart-shaped tomatoes. Extremely early for an indeterminate, often beating other large heirlooms to the table.

Mazarini – really liked this variety, planted 2 vines from Biotehnika and 2 vines from Tanyusha from Rostov. Beautiful plants and fruit, set a ton of tomatoes, great yield.

Growing this variety for the second year. Last year I was thrilled, but this summer ruined the whole impression! Didn’t start setting fruit until after the 12th leaf, even though they were planted at an angle (trenched). But I’m still absolutely gonna plant it again next year!

Grew 2 vines in the greenhouse in 2012, seeds were from Biotehnika, indets. Really liked the variety, ripened earlier than anything else – sown March 15th, first fruits were ready on July 8th. Beautiful color – pinkish-crimson, hearts, flavor is really good and juicy. Tons of blossoms per cluster, if you don’t thin them out you’ll get a ton of tomatoes but they’ll be small. If you prune some blossoms off, the fruits get bigger. The plant is “dainty,” stems aren’t thick, leaves aren’t huge – meaning foliage is pretty sparse 😀, so it doesn’t shade out its neighbors.

My seeds were from Svetikk. Grew outdoors in the dirt. Didn’t cover them at all all summer. Barely got hit by late blight. Extremely productive. Personally, I wasn’t crazy about the flavor, seemed a bit bland to me. Photo is from August 9, 2013. Late blight showed up in our garden on July 7, 2013.

One of my absolute favorite varieties. Planted it for several years, in 2012 I decided to refresh my seeds and bought them from Biotehnika again. Turned out to be a complete off-type. In 2013 I planted the last of my own saved seeds from 2008. The yield and flavor were excellent. Grew them in the greenhouse.

I have mixed feelings about this variety. It was fuss-free as a seedling. And later on too. Based on timing, I’d classify it as mid-early. The yield is monstrous 😲 😲 😲 Sizes are huge (21 oz / 600g is standard, the biggest was 33.5 oz / 950g, but we didn’t get a pic because my mother-in-law swiped it 😆). Beautiful fruit. Pure meat inside. Very few seeds. But!.. We literally couldn’t eat the fruit from the first cluster – tasted just like grass. Then the flavor started improving. Eventually it got really good. Even got slightly sweet and added a bit of aroma.

Thinking that right when the first cluster was plumping up, we got that monstrous June cold snap that turned into frost for a lot of folks. That probably played a role. Overall, in its traits it’s very similar to Eagle’s Heart. Just a slightly higher yield, though they’re comparable.

Anyway, I’m keeping it in the rotation. It’s hard to pass up a yield like that 😳 😆 Going to grow 4 vines out of my total 60… 5-year-old daughter for scale 😀

Mazarini is a great variety! But it’s for the South. For us up here in the Northwest, it’s better to grow it in the greenhouse and treat it with Bordeaux mixture a couple of times before fruit set! I save my own seeds and it gets more vigorous with every passing year. 👍

I agree with Lida. 🌺 I’ve had Mazarini growing outdoors in the dirt two years in a row. It was one of my earliest indets. And the yield is extremely good.

Ladoga (Anzhela) ⭐ Pro Grower (1,816 posts)

I like this variety for its delicious sugary fruits. Planted it several seasons in a row, noted the low yield, but I pick my fruit fully ripe off the vine, I don’t let them ripen on the counter, and these tomatoes are huge, so while they take their time ripening, the others on the vine stall out. My biggest were 24-28 oz (700-800g), mostly 10-21 oz (300-600g). The plant is dainty, the leaves are thin, it catches late blight among the first. But I’ll still keep planting it because the fruit don’t crack, they are meaty, no white core, and no hard green shoulders near the stem. Even if it’s only a few fruits per plant, they are just so delicious.

Really loved this variety! An absolute “yes”. Tall vine, doesn’t get overly vegetative (fatten up), moderately leafy. Set a ton of tomatoes, all beauties))) Started ripening earlier than all the rest. The vine throws both heart-shaped and flat-round fruit. Really tasty, no acidity. Moderately juicy. Seeds from Biotehnika. Looked gorgeous grown outdoors in the dirt too.

Height is about 3.5-4 ft (1.1-1.3 m). For the South, the vines are a bit weak (wish they had more robust foliage 😞). But aside from that – one of the most delicious ones. Yield is average (I attribute this to the heat, but maybe it’s my fault). Sown in early March, it starts ripening by mid-July (mid-early?).

It’s my top favorite this summer for producing massive slicers. Didn’t have to thin the clusters, the weather did it for me. The largest one will hopefully weigh in at a kilo (2.2 lbs). Photo isn’t great, taken with a phone. Higher up the plant there are a bunch more tomatoes set.

Tanya, why are yours ribbed? 😳 Or will they “smooth out” later?
D
Dona70 (Tatiana) ⭐ Pro Grower (1,692 posts)

The biggest one looks like it came from a megabloom (fused blossom), and the rest are more or less smooth, even if not super elongated hearts like last year. Now I’m sitting here trying to remember if I sowed from my own saved seeds or from a Biotehnika packet. Can’t remember…

Natasha, I just went out and looked – it’s only the first clusters that are bumpy like that, everything higher up are smooth hearts. I’m wondering why too 😲

Nadine (Nadezhda) ⭐ Pro Grower (11,454 posts)
📍 Volgograd (USDA Zone 5)

The vine was about 4 ft (1.2m), spindly, grew 3 decent-sized clusters, then it just gave single random fruits, didn’t set well because of the heat. Fruit are heart-shaped, there are some flatter ones too, tasty, meaty, sweet. The skin is very thin, I was turning one on the vine to take a picture and peeled the skin right off, and I wasn’t even squeezing it hard.

It’s not the first time Aelita is using someone else’s hyped-up name to register their own OP or hybrid. Based on the description, the F1 from Aelita is completely different from Biotehnika’s heirloom variety.

And here I was frozen in front of the seed rack yesterday, meditating on tomatoes (even though I absolutely don’t need any more :-). I remember Mazarini getting lots of hype on the forum, but that “F1” tag threw me off. Usually I pick Aelita, I trust them more. Never tried Biotehnika once, but decided to give it a try since it didn’t have the F1 tag 😀

Beautiful hearts, flavor improved from the bottom clusters up, first clusters were a bit bland, then it hit that classic flavor. Didn’t yield super well for me in summer 2016, but definitely a variety worth paying attention to. 👏

This is my very first Mazarini. And actually the earliest large tomato I’ve ever managed to grow. Tomato is very beautiful, productive, early, pretty large. Flavor was sometimes excellent and sometimes bland. For me it depends on weather, soil, and sun. Lenochka-Leo from New York gifted me the seeds. Huge thanks to her!

And I only had two seeds. Sowed them. They won’t sprout. I couldn’t take it today, dug them up. Sitting exactly how I left them, not a peep. Took them out. Soaked them in Zircon, they floated. Sowed them again. Not much hope, but I’ll wait. Really wanted these specifically. Am I really gonna have to sow Biotehnika seeds?

Planted it last year. Seeds from Biotehnika. Seedlings turned out to be no-fuss. Tomatoes were meaty, a bit bland. Since they didn’t ripen fully and had green shoulders, most of them went into processing for tomato sauces, and the very last ones got frozen. I didn’t know about potassium back then 😳 Sowed them again this year, gonna try to grow them pretty and sweet.

Mazarini is getting close, a few are starting to blush on the first cluster, cluster has 5 on it, but it’s massive. Seeds from Biotehnika, growing outdoors in the dirt, vine is about 5.2 ft (1.6 m) tall, doesn’t set great higher up, 2-3 per cluster.

Mazarini – Aelita’s hybrid and Biotehnika’s OP variety grew side-by-side. Set fruit simultaneously in mid-July (sown early March). The OP Mazarini is meaty, with tiny seed cavities, rich sweet-tart flavor. First cluster had 4-5 fruits from 6 to 12 oz (180 to 350g), then gets slightly smaller. The hybrid is prolific, has a little nipple tip, tart bold flavor. Clusters of 6-7 fruits from 1.7 to 6 oz (50 to 180g).

Biotehnika’s Mazarini has taken up permanent residence with me, fruit are pink hearts, set an absolute ton, but all the clusters are within 30 inches (80 cm) of the ground, the rest of the 4 ft (1.20m) vine didn’t have time to set. But even that is plenty)

Gella (Anna) 🍅 Member (108 posts)

Pulled one lower cluster yesterday – 4 ripe fruits from each vine (outdoors), the other varieties have only given 0-2 much smaller fruits so far. So it’s pretty early, only the determinates beat it.

Can’t give a weight, no scale, but all fruits are large, uniform in size.

Pink, meaty, few seed locules, tiny. Good flavor.

In our cold, wet summer, Mazarini was my lifesaver. Set fruit among the first, kept me supplied with meaty hearts all summer long.

Yeah, had slight green shoulders, and it didn’t reach its full sweetness potential, but then again we practically had zero sun. Definitely keeping it for future seasons!

The variety is very reliable, extremely productive. And tasty.

Repeated it in 2017, had grown it before, seeds were from Biotehnika. Once again it was the earliest among the indets, ripened fully on the vine. One plant in the greenhouse pruned to 2 leaders showed insane productivity 😛, reliably set glossy round pink-crimson hearts up to 10 oz (300g) all the way to the greenhouse roof until I topped it, flavor is a 4/5, but for that kind of yield, low maintenance, and earliness you can forgive it. Started blushing shortly after early determinates like June and Angelika. A very reliable workhorse variety 👍

Sveta! Another masterpiece!

Took the time to do a rough count: the number of fruits on the vine in the first photo is well over 30! And that’s just the bottom half of the plant! That’s unfathomable! How?! And you get that kind of beauty on practically every variety!

The first year from the Biotehnika packet, Mazarini fruits were exactly like the picture – perfect cones. But year by year they’re getting rounder for me. But still, it’s a wonderful variety!

Well, I found where the legs are growing from (mystery solved). Planted Mazarini from several sources, got a bit mixed up. Mazarini stayed Mazarini, but the seed sources got confused. I got two vines absolutely loaded with these little round nipple-tipped tomatoes. Liked them at first, and now I see their yield is super high. Just identical to the little tomatoes in this picture, exactly what I have.

Planted two vines of Mazarini this year (seeds from a Biotehnika packet). Got different shaped fruit on the plants – on one they were beautifully shaped hearts just like the picture, and on the second one – flat-round crimson fruits with zero hint of a heart. What shape is the correct Mazarini supposed to have? Looking at the photos – everyone has different shapes, both hearts and flats. The flat-round ones turned out exceptionally delicious, but I have a feeling it’s not Mazarini…

Tatiana, my Mazarini is also from Biotehnika since 2016.
From the seeds in the commercial packet the first year, the tomatoes grew with a shape just like the photo – beautiful cones. But there were also some double-hearts. Now I’m growing third-generation Mazarini, meaning I’ve planted from my own saved seeds two years in a row.
Both in 2017 and 2018, the fruit shape changed slightly, but they are still obviously heart-shaped tomatoes, just a bit chubbier.

My Mazarini from Biotehnika (1st year growing) was very tasty early in the season, hearts (like the picture), super productive. Now the flavor dropped off, tomatoes have green shoulders. My conclusion – UNDERFED. I’m against chemicals, I only use manure, weed tea, and wood ash, but I got lazy… underfed it, plus the hot summer played a role. With a high yield, you gotta feed more. Planning to repeat next season. Oh, and it was the earliest of the indets.

Mine had shoulders this year too. Also underfed – just didn’t have the energy left for them 😳

Those are some nice looking tomatoes you got, are they very juicy? Where did you get the seeds?

Very juicy and meaty.
I bought the seeds initially at Leroy Merlin, and then used my own saved ones.

I’ve been growing Mazarini for 6 years, 5 of them from my own saved seeds. And I have no intention of dropping it. It’s my reliable helper.

Mazarini from Biotehnika in 2019 and 2020 grew to 5.5 ft (170 cm). Fruits were tiny hearts with zero flavor.

Grew Mazarini for the second time in 2020, earliest of the indets, tasty and sweet, used my own saved seeds. Fed and watered it more this time, no green shoulders. Tomatoes are early, large, and prolific, will definitely grow again.

Good afternoon everyone! Found some Mazarini seeds from Uralsky Dachnik in my stash. Good until 12/2019. I’ll try sowing them. Has anyone grown the Uralsky Dachnik seeds, what can you tell me?

Very good and productive variety! Really fell in love with it this season!

Full Summary: Mazarini

  • Growth Habit: Indeterminate vines grow to about 4 to 5.5 ft (1.2-1.7m). It has “dainty” or wispy foliage, meaning it won’t shade out its neighbors, but it is highly susceptible to early and late blight. Needs good airflow and preventative spraying.
  • Extreme Earliness: Dozens of growers reported Mazarini as their earliest ripening indeterminate heirloom, frequently beating mid-season slicers by weeks.
  • Yield & Shape: Immensely productive, setting giant clusters. Fruit shapes naturally segregate over generations, sometimes producing perfectly smooth hearts, flat-round slicers, or double-hearts. Sizes range from 10 oz to well over 2 lbs (300g to 950g).
  • Nutritional Demands: Highly susceptible to potassium deficiency under heavy fruit load, leading to hard green or yellow shoulders. Requires aggressive feeding (potassium/wood ash) during the fruiting phase, particularly in hot weather.
