Fermentation School: Learning from Others
On Tuesday of this week I went over to Madison’s to watch her make her second fermentation. Second fermentation is when you flavour and add carbonation to your Kombucha brew. She shared a bottle of her second ferment with me that I am anticipating trying.
I wish I had been more proactive in taking photos or a video to document this learning journey as I only took two photos and they are not that great of quality. In this photo on the left she is showing me that you need to leave at least an inch in the top of the bottle. She also recommended these air-tight, glass, flip-top bottles. When pouring in the Kombucha from the first brew she strained the kombucha and filled the bottles about half full before adding different flavours of juice.
The photo on the left shows the type of juice she adds to her second ferment. Her favourite juice flavour to add is Raspberry Juice. Madison recommended leaving the bottle for about 7 days at room temperature. After about 7 days the bottle can be transferred to the refrigerator to halt fermentation and prevent over-carbonation. Refrigeration, she shared, prevents it also from becoming too sour.
Madison also shared with me a SCOBY that she separated from another SCOBY. I was a little worried about my previous Amazon SCOBY as it is living on the bottom of the jar, (and later a comment from Matt) so I was excited to try this time a version with Green Tea.
On Wednesday, a new jar arrived as well as some pH strips. Wednesday evening, I brewed a new batch of Kombucha and changed out the cheesecloth covers for a thicker weave of bamboo cotton material.
Scrolling for Answers: Overthinking the Bubbles
Thursday, in reflecting on TikTok’s potential for education I thought I would explore creators who posted about “second fermentation”. Simply Moods by Ida was an interesting account as well as Cakebrain. Another creator recommended burping Kombucha once every day or every other day after three days of fermentation to prevent Kombucha bombs. There is a lot of crazy content on TikTok also. #burpingkombucha. There is a lot of content about exploding kombucha which makes for dramatic content. I was a little worried about a Kombucha bomb, so I tried opening the flip-top bottle, but there was only a little carbonation. Perhaps I should have waited 7 days as Madison suggested. I closed it up again and thought I would look further into tips about flat Kombucha on TikTok, manifest.kombucha had an interesting TikTok about decarbonating Kombucha that was in your refrigerator. Searching “kombucha flat” did not give me the search results I was looking for rather it was mostly about flat stomachs. I discovered that searching for specific content may not be the intended use of TikTok. Rather coming across interesting content creators such as the Cultured Guru, a food microbiologist teaching people how to ferment, and following those tangents seemed to be a better use of my time. My questions/concerns about second fermentation I realized were best answered outside of TikTok. I am a little apprehensive about the user agreement for TikTok. While I do not plan to link my CapCut account to TikTok and share my financial information, I made a small video on CapCut to test out the idea of making a short video less than 30 seconds and of the same resolution 720p as a TikTok video and posted it as a short on YouTube (my first ever YouTube short!) I have deep admiration for content creators that can take 30 seconds and make it also educational.
Video Experiments: pH Practice
As soon as my pH strips arrived I was testing different pH levels. It reminded me of Chemistry class. I think I am right on track. The Green Tea was initially 5.5. Then after I added in the SCOBY and starter the pH was around 4.0. Today it was around 3.0. Here is another YouTube short I made. By contrast the Amazon SCOBY trial batch number 1 still is around a 4.0 or maybe even 4.5.
The ultimate test is taste. Amazon batch surprisingly still tastes like sweet tea so I think with a pH still near the starting point this batch may not have taken. By contrast, the batch from Madison already tastes tangy! Follow along next week to see where the fizz, fears, and fermentation will take me!
