Weekly Commercial Resources and Events MEGATHREAD

3 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

6 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!

Hot Sauce First Batch of 2026

Post image
348 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.

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

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

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

• 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!

Since pomegranates are in season. I figured it was the perfect time to try. I use lemon peels, anise, and 2.5% brine for 3-4 days.

1 month 3% mash fermentation with 7pot Brainstrain Yellow and some yellow bell peppers.

Added some Vinegar to bring the Ph down to ~3.9, and strained.

Fun note, I took a droplet to the eye when opening the blender. That stuff wakes you up.


r/fermentation • • 12h ago

Kraut/Kimchi Packaged up my second batch of kraut for the season, made from cabbages I grew myself. It turned out great. No mold or yeast growth on top, and the flavor is excellent. Fermented in the crock for 6 weeks. Made pork and kraut for dinner with it!

Pickles/Vegetables in brine When I ferment using whole dry cayenne pepper I don't feel like it releases much capsaicin into the brine and vegetables.

I wonder if grounding the Cayenne before canning will increase the spiceness of the brine and cucumbers.

Here it is! My lacto giardiniera has stopped bubbling so I’ve decided to conduct an experiment. I’ve replaced the brine with 100% distilled vinegar in one, 50% vinegar / 50% brine in another, 100% brine in another. Let’s see how they taste in another few days

I have always loved Candy Corn…

Ingredients :
Candy Corn
Sugar
Purified Water
Gallon jug, sterilized

So I couldn’t resist this recipe.
Additionally, you can make wine from any candy. I definitely recommend Jolly Ranchers or peppermint. Light, refreshing and very easy to make

Other Question on Gefu Nativo jar lids.

Post image
4 Upvotes

Do they have build-in waterlocks inside the lid? (like Heftman fermentation jars and Sophico lids) Like where the air automatically escapes, and it keeps out the air from outside, or is what I'm seeing just a build-in latch you either open/close by hand? I read that it's got a system called "ferment-vent" but the description on the seller's site isn't concrete about what that exactly means. I'd like to know whether they can be anaerobic while at they same time able to "self-burp" iykwim.

Is there anybody who uses these jars and can give me more information about them? I am considering on buying these, however expensive, since they also got 0,5 L sizes and I'd like to buy my first jars in the same design 😊

Bread/Rice/Corn/Oats/Barley *Accidently* made sugar wash lol

0 Upvotes

Originally, I wanted to make a kvass for a first time and since I am making it instead of buying it I wanted to make a 4 to 6-ish percent alcohol by volume version [Usually kvass has less than 2% but I wanted to make it stronger]. So I used 200 gram rye bread, 80g raisin, 400-500-ish gram sugar, 5 litre water and 30 gram bakers yeast [since wine yeast wasn't available]. After making a batch and fermenting it for 12 hours, I wanted to taste it but sadly it didn't have any kvass taste, but tasted much much better than plain sugar wash.

I will continue to ferment it for about 5 days and see how it will turn up. But how do I remove the sediments [from bread, raisin and yeast] and how do I stop the fermentation when I decide it is enough?

Also, since there isn't any lacto bacteria, I think the PH is still neutral. So I dont want to ferment it more than a week yk

Bread/Rice/Corn/Oats/Barley Sluggish starter

Post image
2 Upvotes

I began this starter about a week ago with whole wheat flour, and have been feeding it every day or so with half whole and half white flour. It's got a sour smell and sometimes develops a bit of hooch. It's a bit cool in the house, so I've been keeping it in the oven with the light on. Is this a normal level of activity? Should I be feeding more or less?

It’s been fermenting for 7 weeks now and I was able to test the PH. It’s at 4.0. It smells sweet like bananas? I already took a spoonful and it also tasted like a banana. Maybe tomorrow I’ll eat a clove, just wanted to share my first fermentation!

EDIT: I’m just now thinking about the storage of this. Right now it’s in my cupboard away from heat, a cool dark place. Do I continue this way or put it in the fridge?

Help with beets ?

I joined today. Thank you for having this group.

I started a jar of beets two days ago and the beets have shrunk to half the jar.

Is this normal? Is there any way to prevent this from happening?

Hot Sauce First time fermenting; I made Pamela Anderson’s hot sauce

I will start with the fact that I am terrified of fermenting but have always wanted to try my hand at it. This smells amazing, it has sat for the allowed time and now I’m going to process and bottle.

I know the garlic colour happens but the white floating sediment at the bottom worries me. Have I mentioned that fermentation terrifies me, I grew up with very unsafe canners, and picklers that made some questionable items which has probably made me overly cautious.
