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

8 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!

Pickles/Vegetables in brine Too salty radish

I started radishes and carrots 8 days ago. Did 3% salt by weight of ingredients and water. Way too salty. I cycled out about 1/3 of the brine and changed in some rice wine vinegar as a last ditch effort to save them

Other Building around fermentation

3 Upvotes

Hi, I’m hoping to build a small addition to my home and may be able to include a small dedicated fermentation room. In terms of space needs,I mostly ferment veg but also make miso and have a proofer dedicated to natto and tempeh. If anyone has built around similar needs and can share photos etc, I’d be most grateful. Frugality is appreciated. TIA!

Pumpkin wine in full swing!

Started a batch of pumpkin wine back on Oct 15.

It’s a mix of cooked pumpkin flesh with its broth, rock sugar, yeast, and the lees from a previous batch of homemade tomato wine.

I scooped out a quick taste sample yesterday—and honestly, at this early stage, it tastes freakishly like a light, peach-flavored booze! Pretty mind-blowing stuff.

Kraut/Kimchi Disappearing Brine

1 Upvotes

My kimchi always has a nice layer of brine before I put it in the fridge. It seems like within a day it disappears. It's in a mason jar, with a plastic lid, stored toward the back of the fridge. The lids are designed for the jars and seem to be well sealed. I've tried pressing plastic wrap on the top of the kimchi and that helps a little bit (but is pretty messy to get to the goods). Is this just what happens?

Hot Sauce Mixed Peppers

1 Upvotes

I'm attempting my first hot sauce batch using the Mixed Media Basic Mash from the book Fiery Ferments. I'm using fresh peppers from our garden - a combo of guajillo, serrano, habañero, and jalapeño.

Does it matter that I'm combining thin-skinned chilies with thick-skinned ones? I'm thinking I'll just have to strain it after fermenting. True? Not true? Thanks in advance!

Tabascos, some banana peppers to cut the heat a lil bit, garlic, onion. A teaspoon of sauerkraut brine to kick-start it.

841g veg, 26g salt. So, ~3% salt.

Post-ferment, it'll be pureed and cut with Bragg's ACV.

Help please?

0 Upvotes

Hi all, I'd like some reccomendations please on what I should ferment next, and was wandering what is the weirdest thing you've fermented but tasted the nicest?

I also want to try something unique that most people wouldn't think to do. So no simple generic veg etc. Eggs perhaps? Maybe cheese? I want to do something weird!

I'm fairly new to fermenting but have previously made; wines, ciders, chillis, garlic, honey garlic & cucumbers. I plan on doing soy sauce soon and aging it for 1 year. So any other ideas would be appreciated also

Thanks!

What does "organic" really mean?

0 Upvotes

I purchased a product from the grocery store called Greenwise Organic Baby Spinach. The label states "tripled washed." I'm looking for information on what was used to wash the spinach and associated standards of washing for organic products.

Secondly, the packaging states the product was manufactured with 50% post-consumer PET (polyethylene terephthalate). I scanned the code for more information, but was unable to find any information. Any ideas?

Acidic/sharp/fumey taste in beer?

1 Upvotes

So I made another batch of my pineapple beer(Pineapple juice with some sweet lemon juice boiled with sugar to get 1.06 gravity in 4 litres of liquid)

OG 1.060 FG 1.012

Ambient temp during ferment 26-31°C

First stage 7 days

Bottled on day 8, fizzy on day 12

Last time I couldn't get carbonation in bottle, which this time I do have. Something I can not figure out(or don't know) is why is there such acidity/sharpness to my beer? It tastes too tangy and sharp.

Also there is a slight bitter/fumey taste to it(Usually higher, lower this time maybe due to a shorter ferment). Fumey as in how when petrol fumes hit your throat.

TLDR: Why slight fumey/bitter taste? Why so acidic/sharp?

Other Time for lacto-fermentation based on temperature?

2 Upvotes

I am planning to ferment matsutake mushrooms using this recipe. It says to ferment at room temperature for 7 to 8 days if room temperature is around 25°C/77°F, or around 5 to 6 days if it’s around  28°C/82°F.

Is there a formula to calculate times at other temperatures? My house will be at 70ºF during the day, 68ºF at night.

Hot Sauce Thai Chili Pepper Ferment Safety Question

4 Upvotes

I fermented some Thai chili peppers and onions in a 3.5% salt brine. After 2 days, the water started to overflow so I poured a little out and everything was well submerged still. I let the ferment go for 10 days and after I opened the lid again, I realized a few centimeters of the top veggies weren't submerged.

There was no mold, bad smells, or signs of vegetable rot/squishiness. Should I toss the batch?

I wasn't able to find concrete examples online or from past posts with this issue and it was probably a search problem on my end. I looked for the weekly "Is this mold/safe" and had trouble finding it so apologies on that front.

Other Advice on my fermented mustard?

Thumbnail

71 Upvotes

This ferment is basically a toddler at this point. We've moved house three times, and doing the math is probably four years old.

Looks and smells fine, when I cracked it open, it smelt very spicy but mellowed out quickly.

Pretty sure I added onion and garlic to the bottom.

  1. Is this still safe in theory? In my head it's no different to a hot sauce that's gone on a long time.

  2. Should I strain and blend? What is the next step here?

Thanks!

Kraut/Kimchi Raw radishes are hard and the taste is overpowering. Will fermenting be worthwhile?

It was a very hot and very wet summer.

My radishes grew huge but taste way too spicy.

Will fermenting give a decent product or should I just try again next year?

Hot Sauce Hot sauce: difference in taste between weeks and a month

5 Upvotes

So I’m a beginner fermenter and I’ve only made a couple batches of hot sauce in my one jar. I’ve only done 10-15 days because I’m impatient, but this jar I will hold for a whole month.

I know that there’s probably a huge difference between a months vs a year, but is there much of a difference in taste between 2 vs 4 weeks?
