  • My First Brew - Lessons Learned by a Kombucha Brewer

    by Cody Cardarelli

    Hey folks!

     

    Last time we chatted, the police were chasing a suspect across my roof in Bushwick, and my first brew was being steeped. After waiting for my SCOBY to form, thicken and fully ferment, I can safely say that I had a brew's worth of probiotic… well, vinegar.

     

     

    This first-time kombucha brewer was devastated. I had just spent an hour trying to tip my jar into appropriate sized-funnels and spilling the lab experiment gone wrong all over the floor. And there I was, trying to convince myself and my girlfriend that the kombucha wasn't an unmitigated disaster, while my roommates gave the familiar and equally reassuring notion that it wasn't, "that bad." I followed our instructions to the letter, and I came into work asking the usual questions such as "Why hasn't my baby SCOBY started forming yet?" or "What's that strand hanging off of my baby?" How could I have gone wrong?

     

     

    The truth was, I was in the throes of what I like to call: New Brewer's Syndrome, or NBS. After spending so much time fretting about the specifics of my brew, I'd forgotten that SCOBYs themselves are weird, resilient, alien little things that only need time and a bit of attention.

     

     

    So the next time around, I knew the score. My big healthy vinegar SCOBY mocked and cackled, while I whipped up its sugar slurry of a dinner. I placed my antagonist in its jar of broken dreams and waited. This time, however, I avoided NBS and made a well-balanced brew. For all of my fretting from before, I wasn't paying attention to the taste during the fermentation process!

     

     

    After 4 days when I started noticing activity in my jar, I used a thief to monitor the taste of my brew. After 7 days, it was finally perfect and the road to victory was within reach. This time around, I also avoided the joke that was my previous bottling process and used an auto siphon. This simple instrument saved me a massive headache, and made my brew move like a dream.

     

    Thief and auto-siphon Thief, left; Auto-siphon, right.

     

    With pride I returned to the KBBK office with a growler of my homebrew. The  flavor was even, it wasn't too sweet, and it lacked the funk of some homebrew I've had in the past. This wasn't my first cup of 'buch by a longshot, but it was far and away the most satisfying. My sensei, Chris, nodded with acknowledgment.
     

    Probiotic Date Night Pt. 2

     

    When life hands you probiotic vinegar, you make probiotic vinegarade, or salad dressing! After failing to convert my brew with secondary fermentation containing primarily crystalized ginger, Emily and I used the final bottle of vinegar with a nice Spanish olive oil and some minced garlic in a salad. The vinegar has a nice bite-y tart, and at least we were able to reap the 'buch benefits from this wayward brew.

     

    Happy brewing!

  • Sugar, Alcohol, and Kombucha Part 1

     

    All day long we tell people that kombucha is a “fermented tea,” but what does that really mean? I ask this question because there are a lot of assumptions that are made when the word “fermented” is used.

     

    Sugar Without sugar, there would be no kombucha!

    In reality, while kombucha is definitely a fermented beverage, it’s not only a fermented beverage. There are various other biological activities that take place inside your humble brew vessel.

     

    But when it comes down to it, regarding fermentation, most people want to know two things: the alcohol content and the amount of sugar in kombucha. These two facets of the drink are intertwined. In fermentation, the higher the initial (pre-fermentation) sugar content, the greater the potential for alcohol content. Fermentation is responsible for turning kombucha from super-sweet tea into the slightly sour, low-sugar beverage we all love - that’s because there are micro-organisms at work consuming and converting those initial sugars, among other things. That’s why your brew will become more acidic and less sweet as it progresses.

     

    Not only that, but every brew is different, and some of the various reasons why this is true would be laborious to measure. ‘Buch fermented on the East coast will be different than one fermented on the West coast, in different homes of the same city, etc., based on subtle differences - the spontaneous contributions of “wild yeasts” that will come into contact with your brew during preparation, pouring, or transference, variations in temperature, minute differences in microbe population of your SCOBY or starter, and the many qualities of the nutrient (or “nute,” the sweet tea that becomes kombucha). Those are just a handful, but it’s easy to consider even more - temperature, atmospheric pressure, available oxygen in your brewing area, ventilation, interrupted respiration from moving the vessel, proximity to magnetism, playing Mozart to your brew, and many others.

     

    When it comes down to it, considerations of sugar and alcohol in kombucha, while correlated, are still based on a number of other variables. This also makes it difficult to come to an across-the-board average on caloric content in kombucha when it’s not produced in absolutely consistent conditions, such as in a brewery or laboratory. But don’t let these considerations scare you away from brewing, it’s still as simple as ever.

     

    In subsequent blogs, I’ll flesh out more of the intricacies of sugar metabolism and inversion during kombucha production. In the meantime, throw back a homebrew, and consider becoming your own ‘buch researcher, and of course be sure to let us know what you find (easy to do with our ‘Buch Brewers’ Group on Facebook).

     

    Happy brewing!
