Weekly Commercial Resources and Events MEGATHREAD

4 Upvotes

Because we get a lot of individual requests for posts that may violate rule 6 about limited self promotion, we have decided that we will have a weekly MEGATHREAD for people who want to post events, (virtual and in person), products and apps related to fermentation. The general rules about using this channel for self promotion still apply and the thread will be moderated.

Thread specific rules:

  1. NO SPAM still applies. Don't be posting your event multiple times and every single week.

  2. If you have produced a fermentation specific software or app and are looking for beta testers or the app is free, this is generally ok. Posts that for monetary gain (ie trying simply gain customers but not really contributing the sub) will be removed.

  3. You must fully describe what your post is about and should disclose what you have to gain from it. If you are hosting a regional fermentation conference and a inviting folks to register, for instance, make sure that it's clear what the costs, etc will be.

Finally - this idea is a TEST. If it is a total catastrophe, we will go back to a simple case by case system.

Weekly "Is this safe" Megathread

5 Upvotes

Welcome to this week’s dedicated space for all your questions and concerns regarding questionable ferments.

Fermentation can sometimes look a little strange, and it is not always easy to tell what is safe, and what needs to be tossed and started over. To help keep the subreddit clean and avoid repeat posts, please use this thread for:

  • Sharing photos of surface growth you’re unsure about.
  • Asking if your ferment has gone wrong.
  • Getting second opinions from experienced fermenters regarding questionable ferments.

‼️Tips Before Posting‼️:

  • Mention what you’re fermenting (e.g., kraut, kimchi, kombucha, pickles, etc.).
  • Note how long it has been fermenting, and at what temperature.
  • Describe any smells, textures, or off flavors.

Remember that community members can offer advice, but ultimately you are responsible for deciding if your ferment is safe to eat or discard. When in doubt, trust your senses.

Happy fermenting!

Other Update: Advice on my fermented mustard?

Thumbnail

6 Upvotes

Hello!

I finally got my pH meter. The brine tested at 3.62 which means we're good to go!

Now to figure the game plan, I never got this far in my initial plan before I started this project. Breaking through the top layer revealed bright colours below. For those of you who have made mustard before, what did you do to the seeds post fermentation?

I'm thinking just blending with a stick blender or food processor until ''smooth''. I haven't decided on if I'll include the onion/garlic at the bottom yet in the final product.

Thanks!

Vinegar from Koji Barley

Post image
• Upvotes

Pictured is a vinegar that’s coming on 6 months from when I made the beer from Koji Barley to now. I have misplaced where my actual recipe is. When initial alcohol fermentation completed I racked to a new vessel and I added 20% raw acv to turn it into vinegar. As you can see in the photo a lot of the scones sunk to the bottom and there was more dead yeast and sediment left after racking than I expected. It tastes very bland not a lot of flavor but if you k ow what you’re tasting the koji barley flavor is definitely there. The issue is it kind of smells like funky cheese. Any insight or advice people have is welcome! I also plan on trying again with a mix of koji barley and rye in the hopes a fuller flavor comes through. Also considering aging this in an oak barrel. Thanks again for any help.

Honey Garlic Ginger Ferment

Post image
4 Upvotes

Hi all,

I started a ferment with ginger and garlic in honey around a month ago. I had a self-burping lid on it the first few weeks, then switched to a normal lid as it does not produce much gas anymore. I tested the PH recently and it was about a 5 so I added some ACV and let it do its thing, that was maybe two weeks ago. It is now testing at around 4.5 but im still nervous to consume it! Any info on if it looks okay or not? I want to let it continue to sit on the counter to get the garlic to soften more, but should i put it in the fridge??

Made my first batch of cider

4 Upvotes

*On accident. I drank half of a gallon out of a soft cider that was at its expiration date. Closed it up and noticed it was expanding. So I loosened the cap and left it like that for 9 days and wound up with my first batch of hard cider! Is it common for people to discover cider brewing (or other types of fermentation) like this?

Not shooting for shelf-stable or for it to last particularly long (short months at most), do I really need to bust out the test strips and titrate it down below 4.5 if it's going to live in the fridge anyways?

Hot Sauce First Batch of 2026

Post image
456 Upvotes

For the past five-ish years, I’ve been using the peppers from my garden to make hot sauce (as a hobby). Here’s this year’s first batch. It’s made from a fermented pepper mash (containing Carolina Reaper, Hellboy, Lucifer Primo XL, The Beast, and Naga Black Twister peppers). Time to give these 75 bottles away to family and friends.

Kraut/Kimchi Requesting opinions on jar

Thumbnail

3 Upvotes

Hey all, I bought a couple of these jars from hmart and was making some sauerkraut in them

One batch is doing fine but the other one in this jar had mold growth. I think that might have partly been due to a poor submersion of the bits, but I want to get input on this airstopper in case it's the cause.

I figured this stopper (basically a rubber plug) would let co2 out but no let air back in. Do people see an issue with this for sauerkraut? (I'm also looking to do more ferments like cider or carrots/cucumber)


r/fermentation • • 1d ago

Hot Sauce Honestly, my fridge smells like a hot sauce factory. How do you guys store your opened ferments?

10 Upvotes

Okay so I've been doing hot sauce and sauerkraut for about a year now. The actual fermenting part is fun, but I'm honestly so tired of dealing with them after they go in the fridge.

Every time I open a new jar, I screw the original lid back on as tight as I can, but my whole fridge still ends up smelling like vinegar and garlic lol. My partner is kinda losing it. I even tried those cheap plastic lids once but they didn't really do much.

I’m not trying to buy some crazy expensive setup, just wondering what normal people do here. Does anyone actually use a vacuum pump thingy for their jars, or is that just overkill? Or am I just doomed to have a smelly fridge forever?

Looking for practical setups that actually work. Thanks!

Other Why do my airlocks not seem to be working on the peppers? Do I have an issue with the ferment or equipment?

Thumbnail

11 Upvotes

Left: Dill pickles
Mid / right: Habaneros
Both 3% brine by veg + water weight.

Cucumbers have been going a little longer (~7 days), peppers about 5.

The airlock on the cucumbers (2nd photo) is working fine, the gas expelled has lifted the cap and it’s venting properly. The chilli’s however are not behaving the same. It’s not super obvious from the pics but there is a few cm of headspace between the top of the glass weight and the bottom of the airlock.

I’ve made hot sauces before to great success, but have done it a little differently, leading to a few questions:
- this is the first time I’ve fermented only peppers, I usually have an inclusion such as onion or some fruit, however this time I’ve decided to add any extra flavours in at the end after fermentation.
- I tried a new “cleaning method“ to sanitise the jars before use, on some advice I sprayed the inside with some antibacterial spray before giving a thorough rinse. Could this have an effect? It looks like it’s fermenting normally (the brine is clouding like normal)
- or am I missing something and the airlock is just broken (or I haven’t done it correctly).

A curious follow on question, does pepper hotness (capsaicin qty) correlate to how active a fermentation is?

Thanks all

Looking for tips and tricks for fermented salsa.

2 Upvotes

I have like 30lbs of tomatoes I need to prep tonight or else they'll go bad. I was thinking of making a lot of fermented salsa, among other things.

I have many wide mouth mason jars, pickle pipes, and a few weights. I have a lot of tomatoes, jalapenos, onions, garlic, and green pepper.

I'm seeing varying directions online. Some recipes call for a brine. Others call for just juicing the tomatoes and using the tomato juice as a bring. Some say ferment only between 2-5 days, others say you can ferment for over a month.

Looking for some clarify and tips/tricks.

The weight

Post image
2 Upvotes

Hi guys, after teaching about probiotics in my natural health community, I wanted to show them the basic steps of fermentation then realized I didn't have a weight. I had glass in the past but its been a while..

I put together a few ferments, 2 of which needed a weight, so I just grabbed my daughter's little silicone snack cups, that are flexible. It seemed to do the job and its been a week, the ferment looks fine, smells right but...

what's your thoughts on the silicone being in there while it cultivated? Could it disrupt the process, prevent certain strains from thriving or cause chemicals to leach in??

I definitely instructed them to use glass weights.
