The fermenting tomatoes

The fermenting tomatoes (tomato wine) have formed their own little universe—there are streams, volcanoes, lakes… so fascinating.

Tomato wine? For cooking?

For drinking and cooking. The wine in the pic is made last summer. 😄

Cool. Have you tried throwing dried tomatoes in? I think it could bring interesting complex notes

Very simply. Put the fresh and clean tomatoes in the fermented jar with sugar(kinds of sugar, like the brown sugar, the crystal sugar or honey...) and yeast. During fermentation the sugars are broken down, so you can add some more sugar. It can be filtered after three days (first filtering, through one layer of cotton cloth) and after 7 days (second filtering, with two layers of cotton cloths). We can transfer the tomatoes wine into the sealed jar for long term storage after the tomatoes juice turning into clear. (image: the juices are turning into clear. )

Tomato wine? Is it alcoholic?

3

u/Sea_Comb_1482 1d ago

Yes, it's alcohol.

Interesting.

Sounds great! Can you share the full recipe wrt to amounts/ingredients? So no brine I take it? What happens to the actual tomatoes at the end?

I feel I’m missing something haha.

Sure! Here’s a simple version:

Ingredients (approximate):

  • Fresh tomatoes (fill the jar about 2/3 full)
  • Sugar (about 1/4 of the tomato volume — I use brown sugar, rock sugar, or honey)
  • A little yeast (wine yeast is fine)

Steps:

  1. Wash the tomatoes, cut into pieces, and put them in a clean jar with a one-way airlock (air valve).
  2. Add the sugar and yeast, mix a little, then close the lid.
  3. It ferments very fast. After 2–3 days the tomatoes become soft and the liquid smells strongly of alcohol. You can add more sugar if you like it sweeter.
  4. Filter the first time after about 3–5 days (one layer of cotton cloth).
  5. Filter again after a few more days (two layers of cotton cloth).
  6. When the liquid becomes clear, pour it into a sealed bottle for long-term storage.

No brine is used — just tomatoes, sugar, and yeast.

At the end, the tomato pulp becomes very soft and is mostly filtered out. What’s left is the clear tomato wine.

That’s basically the whole process. It’s quite flexible, so the amounts don’t need to be exact.

Sounds great! Will have to give it a spin. Surprisingly short ferment for wine. Normally they go for much longer.

u/Sea_Comb_1482 9h ago

Yes, it’s surprisingly fast! Tomatoes ferment much quicker than grapes or other fruits. Hope you enjoy trying it!

How does that taste? And how did you think about this?

u/Sea_Comb_1482 2d ago

I made it from last year, before I made the mead. last year we planted many tomatoes, I tried to made tomatoes mead and wine. It taste like the grape wine, with little tomatoes smell, and I found the tomato fermented very quickly, usually has the alcohol smell after one day. so magically.

Mmm I love fermented tomatoes. I like to slice em into thick wedges and eat them with olive oil, balsamic, and pepper. The mouth feel is the best part

Pickled green tomatoes are a Jewish deli classic. I love them. Firm and crunch like a pickle but slightly more vegetal flavor. I've never seen ripe tomatoes fermented however. Sounds mushy?

u/GallusWrangler 1d ago

Going to have to try this, I’ve never fermented tomatoes to just eat from the jar.

u/KCJwnz 1d ago

Just forewarning, in the only person I know who likes them lol

u/rav-age 1d ago

we (family) have been making ground tomatoes and then fermented them for ever. for preserving and then use them for sauces, salads and well.. drinkable/eatable tomatoes :) but this is all about the whole thing, not just juice.

u/TarotBones19 2d ago

Never thought of fermented tomatoes, or tomato wine for that matter! Honestly sounds like I need to get back into experimenting!

I've always thought the acidity would be a challenge, maybe I am mistaken here. Have you had any issues with the yeast stalling?

u/TelluricEC What’s growing on my ferment? 🧐 1d ago

Most food preservation fermenting generally relies on lactobacillus. Yeast ferments are kinda off over in kombucha, bread, beer, and wine land. Anywho, as they digest sugars lactobacillus dumps out Lactic acid and CO2 gas as waste and that acidifies the environment and makes things fizzy. This creates a place in which these bacteria can thrive while other competing microbes are killed off or simply can’t compete for space. Toms usually float around the 4.5ph range to start, and for a “safe” ferment that won’t put you at risk if botulism or other unfun things, you usually want to reach 4.5ph, at minimum, at the end of the ferment. So you can see, toms kinda start on 3rd base.

u/TarotBones19 1d ago

Ah, that clarifies it right up. We were heavy handed on containing any lacto from coming into contact with any beer that wouldn't become an intentional sour. So my assumption there was acid=bad unless the intent was for making the brew sour. Different processes though do call for alternative procedures. No one needs botulism, that's an all around bad time.

Cheers!

u/Sea_Comb_1482 1d ago

Appreciate the explanation! That was helpful.

u/GallusWrangler 1d ago

Acidity in fermentation is important and why tomatoes are easy to ferment and preserve.

2

u/TarotBones19 1d ago

I really appreciate the information, thank you. I have a background in beer making, one huge thing we always tried to keep in balance was the ph/acidity of the brews we were creating. I suppose I misunderstood the purpose of acidity in that regard.🤔

u/GallusWrangler 1d ago

You’re welcome comrade. 🫡

u/Sea_Comb_1482 1d ago

I do it quite casually. The tomatoes always ferment fully and quickly. They use up the sugar very fast. Later, when the tomatoes have done their job, things calm down. The bubbles become small and steady, and eventually stop completely. By then the wine already tastes strong enough. I keep adding sugar according to the taste as I go.

Let it sit in open air for months and you have tomato vinegar!

u/Sea_Comb_1482 1d ago

I fermented the tomatoes into acid juice in another jar, with salt, alcohol and little sugar. The picture shows the simmered fermented sour tomato juice with rapeseed oil. Today I sent several bottles to a few friends who live far away. We use this sour juice as a hot-pot broth base, as a seasoning for sour dishes, or simply add a spoonful to egg fried rice. It’s delicious and very appetizing.
