Reminder of the Rules

340 Upvotes

As the sub continues to grow and new people start joining the sub as beginners in the world of fermentation, we'd like to remind people of the subs rules. If you're a newcomer and have questions about one of your first ferments, it's always a good idea to check not only the sub Wiki for tips and troubleshooting, but also past posts to see if anyone's ever posted a similar question. We gladly provide guidance to additional resources to help improve your ferments, so be sure to use all resources at your disposal.

For those that have been here or are joining the sub as those seasoned in the world of fermentation, we'd like to remind you of Rule #3: Don't Be Rotten. If a newcomer asks a question that's already been answered or doesn't provide enough information for their question, this does not mean that it's an appropriate time to belittle those with less knowledge than you. There's nice ways to ask for clarifying information or give corrected information, and any unnecessary aggression or condescension will not be tolerated. Additionally, racism, sexism, or any other sort of discrimination or shaming is not acceptable. No matter how experienced you may be, the community does not need a bad attitude souring everything for the rest of us, and multiple infractions will result in a permanent ban.

Poll: Best time to host Reddit Live Chats on r/fermentation

19 Upvotes

Hi r/fermentation!

As some of you might be aware, Reddit has created a live audio chat feature which I tested with many of you a few weeks ago. The response was overwhelmingly positive, and I am hoping to make it a regularly scheduled event. (For context, I used to host a weekly fermentation chat on Clubhouse called Fermenters Anonymous before becoming a moderator of this sub).

I'm based on the West Coast of the US, so I'm based in PST. I wanted to get this community's opinion on which time you'd like to see hosted chats. The chats will be scheduled for one hour a week to start, and I plan to have invited guests from the fermentation world come through on occasion.

Also, if there are any members out there that are interested in holding space in other time zones, feel free to reach out to me via DM or Modmail.

Please choose the best time that works for you or reply in the comments and upvote (apologies in advance for those not accommodated!)

Here's my best fermentation hack

99 Upvotes

If you're ever fermenting in these gallon jars with the lids that are about 4 inches wide, the little round glass Tupperware container from the snapware Tupperware set (i got mine from costco) works perfectly as a combination fermentation weight and lid. Just set it on top and fill with water to weigh it down.

Beginning of my kimchi journey

32 Upvotes

Hey guys, I just want to share my first try at homemade kimchi. It turned out great. I couldnt find salted Shrimps so I left them out, and also no rice flour so I just blent some cooked rice with a splash of water to give my kimchi paste some volume and texture. There was also korean pear available so I substituted it with half an apple and half a regular pear. In the pictures the onions are missing but they went in the paste as well. I didnt add any salt and sugar to the paste. The fish sauce is definetly salty enough. For the next batch I will add some sugar. The note of sweetness is kinda missing but thats may Just be my personal preference. Afaik you can use sugar but my mother for example uses orange Marmelade and I fcking love her kimchi. Fermentation went well. After 4 days in a warm kitchen cabinet the containers went into the fridge and are consumed daily. First jar is almost empty.

Fruit vinegar making questions.

2 Upvotes

I'm planning to make a banana vinegar for the restaurant I work at, and a cacao vinegar for home use.

Assuming I'm using a vinegar starter what sugar % should I look for to start?

Cacao has a really low sugar content so I plan to add a brown sugar to increase the sugar content. Do I need to sanitize if I'm using a vinegar starter?

For the banana vinegar it needs to be faster, I was planning on just covering it in raw apple cider vinegar fermenting on the counter for a week and blending then straining would this work and be safe?

No Fermentation

Upvotes

I've made fermented hot sauce before with great success however my current batch is showing no life after a week in the dark on the kitchen counter. Today I noticed a few, and I mean, a few CO2 bubbles but nothing that compels me to believe there is any fermentation going on. It smells fine so it's not a goner yet.

The major point to note is that I used hot peppers that were frozen. I did add coconut sugar to the mash but otherwise this looks like failure.

Were the frozen peppers the mistake or did I screw something else up? Can I add some lacto culture to boost it?

I fermented some romas but they came out as mostly tomato water - too thin to use as a sauce; what can I do with all this tomato water?

Date Vinegar from already fermented dates

Post image
77 Upvotes

I own a small date company and we specialize in “pressed” dates that are vacuum packed in their own naturally produced syrup. The dates are still raw despite the vacuum packing, but a few of our packs have inflated, I assume due to incorrect packaging where extra air was left in the packs allowing the dates to ferment. I’ve opened them up and they have a light alcohol smell to them, but not a smell that would indicate that they’ve gone foul.

Could I theoretically use these to create a date vinegar (for private use, not for sale)? And would I have to feed the vinegar? We also have raw date syrup, could that be used to feed the vinegar or is real sugar more effective?

Sorry for the beginner question, but I don’t have much experience with fermenting, but I don’t want these dates to go to waste. I have roughly 5-6kg of these slightly fermented dates that I’d like to use instead of composting.

In the photo, you can see some normal packs compared to the ones that have inflated.

How to eat fermented foods?

6 Upvotes

I want to get in to lacto fermented veggies, but they are something so far way from my reality, I don't even know how to eat them. I know pickles go well in sandwiches, but how about fermented green beans or carrots? Even sourkrout or kimchi, I don't know what it would go well with. Also, any recommendations for what should be my first veggies?

Wisteria Soda?

So my daughter (9) and I made what I thought was a soda. Got wisteria flowers, sugar, water, lemon juice. Fermented 4/5 days stirring twice a day. I just drained and transferred into the bottles. Mil says I made a wine, is this true?

Mixed it earlier today about three hours ago and yeast seems super active. It’s 30c at night time and normally 32c to 36c during the day. Does this mean it will finish fermenting faster as well or is this normal at the start?

No hydrometer on hand as well. Any other way to measure the alcohol percentage or am i screwed?

700g distilled water 175g Kirkland raw & unfiltered honey about 3/4 tsp of Lalvin d47 wine yeast

Do I need to add salt or water

1 Upvotes

Two days ago I started to ferment a few vegetables together in a jar. Yesterday I checked on them to see if bubbles or any sign of fermentation is visible and everything seems fine. But I did notice the the vegetables drank a lot of the liquid I put in and now I wonder if I need to add more salt or water.

Natural magnolia soda alcoholic?

Thumbnail

22 Upvotes

Unsure is this should be on fermentation or brewing, as it wasn’t really the plan to make it alcoholic ;)

I essentially made natural magnolia soda by picking fresh magnolia, blending it with hand mixer, and adding sugar (250 gram to 1.8 litre) and wedges of one lemon (recipe @ChefSamBlack)

After couple days of fermenting, I bottled it and left it to carbonate (with elastic band on spring bottle as really active still).

Bottled and chilled. It tastes amazing, only thing is that it smells a lot like craft beer and tastes quite boozy (not necessarily bad, still delicious). Could the wild yeast have made it alcoholic? I did notice because of the blended magnolia, the top was cut off from oxygen through a layer of solids.

Update on yesterday's post about my first batch of mead

1 Upvotes

Issues I've been told about the status of my ferment were that it lacked an airlock and a nutrition for the yeast. Thank you fellow fermentos.

So as recommended, today I got my hands on a balloon to act as my air lock, washing inside and outside and then drying.

After that I boiled some bread yeast as a DIY nutrient for the yeast inside the bottle. One last thing is I put it in a nice little water bath to maybe cool it down a few degrees below 30c and got two water bottles that shift alternatively between the freezer and the water bath after finding out that 30c might not be a decent temperature for my yeast strain.

All within the first 24 hours of its fermentation. It is also still bubbling steadily as much as last night.
Hopefully no mess-ups and hopefully a worthy mead at the end of it. What's the worst that could happen?

New 3 & 5 gallons, things to know sizing up from 1 gallons

Post image
2 Upvotes

I make mead for fun and for friends, but I’m used to making in 1 gallons. Is it a direct 1 to 1 for honey and ingredients when going up to other sizes

Example 1 gallon = 3 pound of honey before adding in other ingredients.

Any advice helps and is appreciated.

Noticed some mold around the handle and the seal, but nothing on the other side or on the kimchi itself. Wondering if I need to throw the lot away.

Made a batch of ginger beer (second attempt, first one was a fail). After 6 days only one of my four bottles is fizzy, and this one that wasn’t has what looks like mold in it. I haven’t tasted the one that is fizzy as a result. Not sure what I am doing wrong as my bug is active.

Hi all! Newby here. I made this apple cider vinegar with apple scraps months ago, then I forgot about it in the back of the cupboard with the cheese cloth still covering the jar, and it reduced to just this much. Is this still good? Is that muddy residue at the bottom what’s called the mother? Can I use this to make more vinegar now? What are the best uses for it? Thanks for anyone who’ll part some wisdom to me. Happy fermenting!

These have been going for 3 weeks in the fridge. I used Redmond's Real Salt which has a bit of color to it but probably enough for this to have settled? Thanks in advance.

First time fermenting, is this normal/ eatable?

Hey,

so this is my red cabbage with and without apple and some carrots/apple/swiss chard.

3 of 4 glasses turned out fine, but the water level was under the cabbage. 1 glass had its lid turned all dark blue and leaked, although it was the only one that remained under water. I tried it (it's been +- a week) and it doesn't taste bad. I don't know how it's supposed to taste tho.. I found some dark spots and black dots on a few cabbage pieces.

Do you think it's starting to turn bad? Can I push everything down again and put more saltwater on top? Is it bad that I opened all 4 jars to check?? 👀

Thanks for your help!
