Could you please show comparative pictures of mold vs. not mold? Would be great!

She said that the photos are on her website. I'm going to head over there now to look at them also.

[@Aavnborg]

Just to be clear at 0:55 - bacteria do not cause mold. Mold are filamentous fungi, and fungi and bacteria are not the same or even closely related. But this does not contradict the main point, that the lowering of the pH makes it more difficult for pathogens - bacteria and fungi alike - to survive and settle in the kombucha :)

[@emceeunderdogrising]

Definitely true.

[@shacheb]

Hi thanks for the amazing information 😊. But last week I took out two of my Scoby hotel vessels one was fine and the other had mold on top. I made two new batches one of which I took the Scoby from under the one that had mold and reused it. I am a bit worried because I didn't know that it should be tossed with the tea. Shall I just throw both batches? I forgot to label them and do not remember which one I salvaged. Thanks again

[@edm719]

Please use metric and imperial measurements and temperature. Thank you keep up the great work.

[@sierraspiral]

I'm so sad that my scoby has mold. I see two green and powdery spots so its deff mold. I left my scoby alone for 3 months without feeding it. Two weeks ago I finally fed it.... but now its moldy :(

[@brunitute2009]

When I went to check my brewing vessel yesterday it had a white right on the outer edges and I got concerned it was gonna be mould and just tossed the entire thing this morning, do you think it was mould? The top had a layer which I believe was the scoby forming but almost looked dry on the surface I never seen that before

[@nicolep2424]

Two weeks in and everything is looking beautiful! (Ugly lol) smelling more and more like kombucha instead of just tea! I'm so excited and appreciative of this channel. U said something about not brewing in the kitchen....I started a fermentation room❤️

[@pete687713]

So, I started making my first kombucha a few weeks ago. I was thinking i didn’t have enough starter tea with my Mother so after a few days i put in a little citric acid (1/4tsp for 15 litres). The SCOBY has grown to cover the top of the jar but it still tastes sweet and not acidic. I live in Ireland so we don’t get great temperatures but it has been 2 weeks and it doesn’t look dead and it doesn’t look like it has any other bacteria growing. How long should it take for a batch this size to ferment to kombucha?

[@smokedhamu]

I spot white settling underneath my jar, is that mold or...? Also your videos are super helpful, thank you! What would happen if someone accidentally drinks the kombucha with mold it in?

[@dianenaidoo7668]

Thank you . .

[@rhondacallahan]

OH no, I have my first tea brewing under a towel with a heated throw over it that I turn on for an hour or so in the morning and evening. I hope I'm not cooking position I live in an old cold house with propane heat only. So thought it was best to keep in warm around 72 to 80 degrees. What do you think?

[@mflores94]

I accidentally, added the new tea/water mixture with warm water to my scoby. I don't know if I killed it, pH was ok - is there any easy way to check with few days that have passed?

[@angelafrancis4968]

Hi thank you for all the information. It helped me a lot. Do you have any other video on KZbin

[@YouBrewKombucha]

I do! I have 31 videos on kombucha on my channel. You can also find more in-depth info on my website: youbrewkombucha.com

[@angelafrancis4968]

You Brew Kombucha Thank you I’ll check them out

[@heatherniemisavage]

I have brewed several batches of kombucha. Some of mine have gone bad and I have started over with new scobys I got from a friend who brews Kombucha. The main problem I have when this happens is that the scoby gets orange streaks through it and the kombucha smells bad. It is a lot like when my sourdough starter goes off. I have assumed this is mold and threw it all out. Now I am looking for a new scoby, so I will watch your video on that. I agree with everyone who says your videos are well done. Thanks!

[@pmst3668]

Hi everyone, during my second fermentation has developed a white stripe around the neck of the bottle. Is that okay? I have put in the kombucha some fruits and apple juice. It definitely does not look like sign after carbonation... I am thankful for every help.

[@sarafinaleade6124]

Thank you. Very helpful. I was so worried about an unhealthy Scoby and Kambucha. You cleared a lot up.

[@lauraharden7204]

I bought a "chunk of scoby" from health food store. Did all the steps and scoby stayed on the bottom of jar for about a week. It has since floated to top but i dont see any other formations on top just a lot of bubbles. Also is smells and tastes like vomit. Im tempted to throw it out and start over but curious to see what it does. Any suggestions?

[@AarysGigi]

Ok, I've been lurking and watching a lot of your videos, figured it's about time I contribute to your engagement numbers and start leaving comments. (I'm already tracking what Ive seen yet or not by liking everything I'm watching.)

[@AarysGigi]

Question.. I'm wondering if you've tried making a coffee scoby for koffucha. I'm looking into this to combine two things I love. However, I wonder how much caffeine the scoby may consume or not and then whether or not the resulting brew would still get someone both caffeinated and probiotic.

[@jbeu2785]

With coffee! That's so interesting I would love to know how if you have tried it :)

[@lofenoialof5320]

What do you do with the new thin SCOBY at the top of the water ? Thanks !

[@elliechapin182]

Are you suppose to wash your vessel or sterilize every time you make a new batch of kumbucha. Can you rinse it really good in hot water?

[@kiwiace625]

My new brew scoby has very tiny white dots happening in a small patch? Any ideas?

[@tomchristensen2914]

can top layer be removed since it is powdery and rest will be ok or should I start over

[@annacretella276]

i found mold on the top of my kombucha motel, There are about 15 scoby's in there, can i disguard the top one and use the ones that are still immersed in fluid in the bottom or do i need to start the whole thing over ? iALL OF MY SCOBYS were in there :(

[@lexyfigueroa5114]

Hi!! I read add'n caffeine to urea kombucha its good! Thats true???🤔

[@mythic_snake]

Sadly, my second batch got mold. I did not touch it for a week, and when I checked it a week later, it had "spots" of mold on top of the pellicle. Very sad, because since it was my second batch, I don't have much liquid in my scoby hotel for a do-over. :( I have some Star-San so I will have to make sure I sanitize more thoroughly next time.

[@oceans1259]

Happened to my 2nd batch too 😭😭

[@amyr505]

Thanks so much. Now I know how my first batch failed.

[@donnac5149]

Do you have to wash your vessels after each batch of first fermentation

[@nancyjm79]

I started a batch about 9 days ago. After about 4 days noticed what looked like pieces of blue cheese floating on top. I went to throw it out and when I picked it up to take to the sink, the stuff dissipated. I decided to wait and see what happens. I have since learned that I probably had it in too cold of a place so I put a seed starting mat under it to keep it warmer. I'm wondering if this was mold, and I changed the pH now that it's warmer and it looks like a scoby is forming, is it ok? Can the mold ever go away and it's OK? Thanks.

[@jonjohnsbakeryllc1031]

My Scoby isn't getting big but I have a new one is that okay?

[@corujabiruta3732]

i have a doubt about mine. see, i was fermenting mead, and happens that two separated scoby formed. i tryed to separate those scobies in a new vessel, a glass pot with the same water-stoper system i use for the mead, than add new brown suggar and filtered water (same water source i used to the original mead brewing). I made every part of this process with the best asepsis I could, the new kombucha is totally isolated from outside source of air, bubbles allways poping from the water stoper. But right in the next day i started to notice the upper side of the scoby is white. i try to shake it daily to prevent mold, but now it is all white and with extreme short-fuzy. no black spots, no circles, no wierd colors just white small fur (like a white sweed)and something jelly-like arround in the liguid. based on this, is my scoby a loss? is it mold? can i recover it? should I comit mass genocide of my precious complex and throw it away?

[@Batsnang]

So I have some opaque white stuff floating on the surface on my kombucha. And there's a grayish spot in the mass. Not fuzzy.. Is that normal/okay?

[@mboukadoum]

Hey, I was wondering I have a scoby who's been in the making for the past 2 weeks and in 1 week I'm traveling for 2 weeks. Can I let it where is it (in a dark spot with the starter tea) or is it going to mold, or should I put it in the fridge to stop de fermentation? Thank you and your videos are very helpful :)

[@YouBrewKombucha]

No need to refrigerate! Just leave it alone in a dark spot at room temp, and it'll be just fine. :)

[@weedsinthegarden4261]

Enjoy your videos. My first scoby I tried starting with vinegar and I cannot say the taste was great. After watching your videos I purchased another scoby that came with starter tea. Much better batch! Quick question. When pouring up the bottles there were some strands that went in with the liquid. During second fermentation they appear to be coming to the top and growing. Normal? Thanks.

[@YouBrewKombucha]

WeedsInThe Garden Totally normal :). Baby scobys often form in bottles as part of the fermentation process. If you like, you can strain them out prior to bottling. And if more form in the bottle, you can strain again before drinking. You can find more of my tips on that here: www.youbrewkombucha.com/strain-baby-scobys

[@BitcoinBV]

Several black strings have in and around my scobie two days after I decanted most of it. Is this normal?

[@maxslomoff]

thanks for the info! hey, If we don't want to brew for a while or are out of brewing containers, I read that we can put the scoby in the fridge. but you say that makes it go dormant and vulnerable to mold. is there a better way to put the scoby on hold for a while? thanks!

[@camilla7347]

Hi I found this video to keep the scoby in the fridge for 1 year, hope it helps kzbin.info/www/bejne/iKTHlZl3j8use6s

[@fitgurl6213]

I purchased a kumbucha kit should the new Scoby float right away? It looks healthy but it's laying n the bottom of the jar. Thnks you have the best direct answers in your videos.

[@YouBrewKombucha]

They don't always float, so that's all good. I cover this and other info on what to expect during F1 in this video: www.youbrewkombucha.com/what-to-expect-f1. Thanks for watching!

[@ikizagirl]

did my first 2nd fermentation of kombucha w mango juice. 2 of the bottles had round white dry crusty looking bits on the surface T.T the rest are fine tho. asked the guy whom i bought my scoby from, he said it's just a scoby forming. but judging from pics online, the white bits in mine don't really looking the same as a new scoby forming....

[@YouBrewKombucha]

ikizagirl Are the white bits dry/fuzzy? Or look like mold that grows on bread/cheese?

What does mold in a kombucha batch look like ? Thanks !

[@sebastianarielburd3119]

Hi, firstly HAPPY 2019, hope u had an awesome time in NY eve two questions to ask: 1) When I 'm done with first fermentation and I want to transfer kombucha tea to a bottle to make a second fermentation, I wonder myself if it is okay to place the scoby in a plastic container only for a few minutes while transferring the fluid to the bottles or the container must be a glass material? 2) the juice I added into the bottle to give flavor when making a second fermentation, is it okay to add juice that I made in blender with water? I wonder if the water will damage the kombucha fermentation? thanks a lot

[@YouBrewKombucha]

Scobys and kombucha can come into contact with plastic no problem, as long as it's not longer than around 24 hours or so (to be on the safe side). And yes, you can totally use juice/water to flavor the scoby. There's water in the tea, which makes kombucha so water won't hurt it :)

[@alphacentauri1757]

Min. 6:45 IO STAR iodine based sanitizing solution Warning: perhaps the solution you present no longer exists. I see on the product in your video that the label has no warning. The version I saw on Amazon has a warning on the label that says: it's a hazardous waste and cannot be disposed of through your sink It's meant for industrial use and it should not come into contact with food. I discovered this in the photos that a user put in the 1 star reviews. Also the photos are to the right of the reviews.

[@katieinboston8729]

So of course I watched this after purchasing a dry SCOBY from an online (somewhat reputable) company that also says to start the first brew with white vinegar. Is there any hope to activate that SCOBY? If so, can I use commercially purchased raw kombucha for the starter tea?

[@madeleinemichanie7205]

Hi there! As long as it is a "raw" unflavored commercial kombucha with all the gunky goodness, you can grow a SCOBY from it. Takes a bit longer of course, but totally possible! :)

[@dfay49]

The company I purchased the SCOBY from said to activate it with 2 black tea bags steeped for 12 minutes then 1/2 cup vinegar. The SCOBY came dehydrated. Yet, it us a reputable company that specialized in fermentation. What do you think?

[@alexisriddle2986]

She said in another video to never use vinegar and to not buy dehydrated scobys and I believe she said not to really trust companies that recommend vinegar. Look at her video about where to get a good scoby from. I'm not sure the name of the video.

[@gourdasilakicevic7992]

Is it popssible to grow scoby from black sweetened tea with sugar and nothing more- by letting it ferment?

[@mt6nin825]

I bought a store bottle of kombucha and a store bought scoby. Why do my store bought scoby look dark, and store bought kombucha nice and white during my first process brewing? Is the store bought scoby old?

[@zavodglobal9308]

Hi, is it okay if your scoby is on the bottom?

[@TheIndustrialphreak]

a little off topic what about secondary fermentation? just finished my first secondary batch and im worried about opossible botulism? if properly fermented and correct pH as well properly sanitized secondary bottles and equipment what risks are there?

[@YouBrewKombucha]

Botulism can't survive in environments below 4.6, and properly made kombucha should definitely be well below that point. Plus, botulism can't thrive in environments that are exposed to oxygen. Every part of the kombucha brewing process involves oxygen (even when you're bottling), so botulism shouldn't really be a factor in kombucha-making. We're not canning or sterilizing anything, so that removes the risk of improper canning/sterilization that could cause botulism. So kombucha should be in the clear... assuming that the person is properly brewing kombucha, of course. :)

[@zoefoery6332]

Hi there! I recently had two of my batches infected with mold, and I was wondering what might be the cause so I don’t mess up again! I had been using a SCOBY that I got from amazon that had posed me no such problems for months. It had even grown thick to the point where I separated the SCOBY in two so I could have two batches going at once. But unfortunately both of the batches developed mold! Could the separation have caused this? Or could it be the lower September temperatures in NY? I’m pretty sure everything was cleaned well and that I added enough starter tea so I’m at a loss :( thankfully I have some scobies in my hotel and I am growing a new one but I am scared to start again and lose my other SCOBY! Any advice is welcome :)

[@potatosmith3482]

Hi there! My kombucha also got infected with mold. I would like to ask if the scoby still grew or a new scoby started to form despite the contamination of the mold

[@RamyVinesandHomesteadTimes]

Keep it in a closet out of the sun or in a colder area in the house. Shouldn't be super bad.

[@marceldeac1876]

@@DrivingWithJake I will try, thank you!

[@teresamcwaters7884]

My kombucha is bottled and done with its second fermentation. What should the yeast at the bottom of the bottles look like? Some of mine kind of looks fuzzy and white-ish and I can’t tell if it is mold or just yeast. You said mold would only be at the top of the brewing vessel but does that still hold true for the second fermentation?

[@YouBrewKombucha]

For the most part, yes -- mold generally only grows at the top (the part that's exposed to air) -- but it's also possible for mold to sink if the bottle's been jostled around. I will say, though, that if your brew has acidified enough to get to the 2nd fermentation phase, and if it's fizzy and acidic, then it's not likely that it's mold because the liquid is likely too acidic to be hospitable to mold. Sometimes, fruit pulp in the bottle can also turn white/light and look a bit fuzzy so it's possible to look a bit like mold. But again, if it's acidic, that's not likely mold. Hope that helps!

[@saullosam]

what do you think about airlocks to make the 1st fermentation?

[@YouBrewKombucha]

I've never tried them, but in general, kombucha cultures do need some airflow (at least during the first fermentation stage) to ferment properly. So the airlock would let carbonation escape, but not let new air come into the vessel -- so that could hinder the fermentation process. But I don't have a ton of experience there, so if you try it, I'm curious to hear about your findings!

[@gyhany1105]

Can I use decaf black tea?

[@sandrabrown4665]

the longer you leave your tea to ferment does it make it more vinger taste or do you test it every few days to get the taste you want

[@YouBrewKombucha]

Yes, the longer it ferments, the more acidic/vinegary it tastes. I typically taste my kombucha around 5 days into the fermentation process to see if it tastes good and is ready based on my taste preferences. You can go here for more info on how to tell when your kombucha is ready/done: www.youbrewkombucha.com/when-is-f1-done

[@souvi8511]

My scoby rised aboved the fluid line and it was just hanging out between air. It has many smooth bumps. I pushed it back down. Is this normal?

[@YouBrewKombucha]

Yep, totally normal for the scoby to form an air pocket above the liquid, and it's totally fine to just poke it back down. It's hard to tell whether the smooth bumps are normal/not without seeing it, but air pockets/bubbles in scobys are generally normal.

[@sebastianarielburd3119]

Hi, how are u? 2 questions to ask: 1) where did u purchase the IO Star Sanitizer? I checked on amazon online and it seems they dont sell it. 2) how do u store the scoby if u are not planning on making kombucha for a while, lets say u are going overseas for 2 or 3 weeks, what is the best way to store the scoby? thanks again

[@YouBrewKombucha]

Hey there, I got my IO Star from a local beerbrewer supply store in LA. You can search for IO Star or StarSan from beer brewer websites which might carry it online :) And you can watch my video on scoby hotels for more info on long-term storage of your scoby. But essentially, just keep it in the brew vessel with enough starter tea/sweet tea to prevent it from drying out or evaporating, and it'll be just fine at room temp, waiting for you to get back. Hope that helps!

[@sebastianarielburd3119]

@@YouBrewKombucha thanks, should I cover the scoby with a lid or still with a piece of clothing, I was told that If Im away for awhile it would be better to put it away in a container with a lid to prevent the scoby from growing

[@YouBrewKombucha]

I'd still cover it with cloth. If you cover it with an airtight lid, that won't stop it from growing (since the liquid will continue to ferment and acidify). But it'll just trap carbon dioxide in the vessel (which could lead to it being overly pressurized while you're away). Best to just keep it covered with cloth or a lid that's not screwed on super tightly so there's still a little bit of airflow and so the excess pressure can escape.

is the black tea or green tea better does it have good taste im not much of tea drinker

[@YouBrewKombucha]

It's really up to you. You'll have to taste different teas and experiment with how they ferment to see what you like better. Personally, my favorite type of tea to drink straight is oolong tea. But my favorite type of tea to make kombucha with is black tea. So it really depends on personal preference. Check out my video on tea for more details: www.youbrewkombucha.com/tea

so my first batch was really sour so I canned it and started a new one with a little bit of the old batch which was sour. its only been 2 days and I feel it smells a bit vinegary...did I ruin my new batch with using a extra sour bit of my old one? or is this normal?

Kombucha is somewhat vinegary. A strong starter tea is a good thing. Sounds like you're doing just fine :)
