Brew Your Own Kombucha Tea

For a few months now, I’ve been drinking kombucha tea in addition to my daily kefir. Kombucha is an effervescent beverage that tastes similar to a tangy apple cider. It’s sold bottled in health food stores but you can brew your own kombucha tea at a fraction of the cost. There are many health benefits of kombucha as well as warnings on the internet, so do your research and decide if it’s right for you.


Jars of sweetened organic green tea ferments for at least seven days.

For me, it’s been miraculous. I am pre-diabetic and need to watch what I eat. No rice – no pasta – no bread – no sweets – no joy. After indulging one night at the movies on a bag of M&M’s, my morning blood sugar reading was significantly lower than normal. A binge like that would’ve seen a sure spike and put me in a sleep-induced coma. Coincidence or was it the aqua fit classes? So I did it again (I love peanut M&M’s). There was a definite pattern. Whenever I drank kombucha, glucose readings were lower than when I didn’t.


The SCOBY (Symbiotic Culture Of Bacteria & Yeast),
is a living rubbery mat that feeds off the sugar in the tea.

From what I can tell, there hasn’t been any medical studies on kombucha tea, except for one done on rats and ducks. Results showed a decrease in bad cholesterol and blood sugar. Again, it’s stuff off the internet, you can’t believe everything your read right? So Hubby is going to be my duck for three months. He will drink a wineglass of kombucha at every meal (lucky he likes it). If kombucha can lower the bad LDL cholesterol and raise the good HDL in ducks, then maybe it will work on Hubby too. Stay tuned for the lab results!

A baby scoby forms on the surface.
Layers can be split and shared to start new batches.

Maybe claims of treating arthritis, joint pain, high blood pressure, reducing grey hair and reversing the aging process is really true too? I’ll let you know in three months!


To make kombucha is very simple and takes very little time. I make two batches a week to keep up with demand. Don’t worry about those stringy brown bits, it’s yeast and tea.

Kombucha Tea

Bring a gallon (16 cups) of water to a boil and dissolve a cup of sugar. Add eight green or black tea bags (I like green tea) and leave it in till the tea cools. Do NOT add to scoby unless it’s cooled, or the heat will kill it.

green tea bagsLike making kefir, cover with something breathable (like a coffee filter) for gas to escape and keep fruit flies out. Here you can see the different layers grown each week. If it gets too thick, peel it off and share, or discard the older layer on the bottom and keep the newer whiter layers.

Kombucha Tea

Leave it undisturbed for 7-10 days. The more scoby, the sooner it’s ready. Have a sniff and spoon a taste. If it’s tangy, it’s done. For me the tarter the better. Internet says to test the PH for acidity (3), but the taste test works just fine. It also helps to write down the date so you don’t forget.

Kombucha Tea

When the kombucha is done, pour through a sieve to catch any lumpy bits. It won’t kill you to swallow, but it is a bit of a shock to feel something slimy slurp through your throat. Make sure you leave about a cup in each jar. You need a little bit of the kombucha to start your next batch. If you don’t have any, you can use apple cider vinegar. The new batch needs to have an acidic environment to keep away mould. Add your cooled tea, pouring only to the widest part of the shoulder. You want to give the scoby maximum surface area to grow. Cover, and repeat process in a week or so.


Kombucha stored in convenient 500mL plastic beer bottles.

You can store the strained kombucha in the fridge, or keep tightly sealed at room temperature for a couple of days. This second fermentation is where you can flavour your kombucha by adding fruit juice or ginger. This will give you a more carbonated drink as the yeast in the kombucha will continue to ferment. Be careful not to over carbonate or your bottles will explode.


We prefer to keep it simple and enjoy it straight up. Cheers!

  • Dana - I’ve just started to brew my own kombucha so it’s great to see how others are doing it also. I am definitely going to bookmark you site to see what the results are with your husband’s health.ReplyCancel

    • Jill Chen - I’ll also let you know if my hair stopped greying! Another claim of kombucha:)ReplyCancel

  • Will Donnelly - Hi there!
    Your cultures are looking great as well as your photos and blog. I work with Kombucha Brooklyn down in New York, and love to see people getting hands on with brewing kombucha. I would just advise any brewers out there reading this that cheese cloth (a common go-to) is too porous for a cover – coffee filters, cotton cloth or even a square of t-shirt works the best.

    If you feel like passing along your hubby’s results, I would be happy to feature it on our site. Not that we claim to be doctors, but we think kombucha is great, and that people’s personal claims hold value as well.

    All The best and keep brewing!
    Team KBBK

    P.S. Peanut M&Ms are my kryptonite as well.ReplyCancel

  • Will Donnelly - Whoops! my email is – not sure if you can see it or not as an admin. Check out our site, as well, would love to hear what you think.


    • Jill Chen - You guys are AWESOME! Love your site. Didn’t know you could prepare scoby to eat, reminds me of jelly fish, I must try it.ReplyCancel

  • Mary - Hi Jill,

    That kombucha tea sounds interesting and I would like to know if after 3 months, it lowers bad cholesterol. In the meantime, I don’t know if you saw the recent episode of Marketplace, but they tested tea and apparently there are lots of brands of tea that have very high levels of pesticides. I never knew that and will try to find a brand with less contamination. Even Lipton green tea has well over the acceptable limits. Too bad as I just found two dollar off coupons! Perhaps you know of some pesticide free teas.ReplyCancel

    • Jill Chen - Hi Mary, I never knew but then again I’m not surprised. I buy my organic green tea bags from Costco. It’s a huge box.ReplyCancel

  • Peggie - Beautiful pics! I’ve been brewing my own kombucha for years now. I even converted my skeptical husband to drinking it! Here’s a few ideas…..I use a 2-gallon glass jar with a spigot at the bottom for brewing – yeah, we drink a lot of it in the summer. I also experiment too. Fruity herbal teas are good and oolong teas make a flowery tasting tea. Last fall I simmered all my apple peels from the harvest, strained the juice off, and added a cup of sugar to each gallon. I added this to the jar and let it sit during the cool fall months, about two months. It made the most delicious apple cider vinegar. I also did a gallon jar with pear peels. You can still smell the pears in the vinegar. While I don’t use it for canning, I do use these vinegars in any other recipe calling for vinegar.ReplyCancel

  • Melanie - The blueberry/pom kombucha was delish! I look forward to following your directions.ReplyCancel

  • Did Kombucha Tea Lower Cholesterol? » FreestyleFarm - […] you’ve read my first post on brewing your own Kombucha Tea, you must be wondering whatever happened with our own “controlled study”. Did drinking […]ReplyCancel

  • Peter Lynch - Hi Jill, just wanted to get clarification on scoby. If I don’t have any, all I have to do is prepare the tea as described, and add apple cider vinegar? I have never had kombucha, but I want to try it, but I also don’t want to spend money if I am not going to like it. Can I just boil water, add sugar and tea bag, and about an ounce of vinegar, cover, and drink? Sounds scary, but I am game.

    By the way, I love your site, and all your projects, almost a mirror of what I “want” to do. Just tied up as primary caregiver for parents, now, and working from home, so I can not maintain much more. But you inspire me. Thanks to you and your family:)

  • Newbie Kombucha Drinker - Very excited about the health benefits of kombucha and very much appreciate your blog! I’ll keeep my fingers crossed that you get the results you are hoping for regarding your hubby’s cholesterol. In the meantime I would like to start brewing my own. Maybe I missed it but I’m not sure about where to get a good starter skoby and secondly, what size jar are you using for this gallon recipe? Do I need a scoby for each jar? Your time and response here are greatly appreciated!

    In good health,
