Continuous Brewing Kombucha vs Batch Brewing

Difference between batch brewing vs continuous brew kombucha by YEABUCHA.  Founder Brooke holding two SCOBYs from a batch brew and continuous brew jar.

When we first dove into the world of home brewing kombucha we discovered there are two different methods: Batch Brewing (BB) and Continuous Brewing (CB). We quickly found our groove with batch brewing kombucha rather than the continuous brewing method. Before we get into WHY we love batch brews over continuous, we’ll explain the difference.

For BB we use 1 gallon glass jars to ferment tea. Each batch involves brewing sweet tea and mixing it with water, starter liquid and a SCOBY. First Fermentation (F1) is complete after 7 days. Here, you test the flavor and decide whether or not to begin the second fermentation (F2) or wait a few more days (up to 14 days for F1). For F2, you bottle and flavor the kombucha with your favorite fruits and herbs, then let it ferment for an additional 2-4 days prior to placing  it in the fridge. There is no maintenance or extra attention required in between brews. After you complete your first batch you will fall into a rhythm of enjoying your home brew each week while the next batch ferments. Every time you brew with BB, you have the opportunity to remove older SCOBYs and yeast, and clean the brewing vessel. The best part is that when you follow our 3 Simple Steps to Brew and Flavor instruction card, it only takes about 20 minutes of hands on time every 7-10 days. (click here to see).

What a SCOBY looks like from continuous brewing kombuchaCB uses a larger vessel (2-5 gallons) with a spigot. The SCOBY is never disturbed because kombucha is removed from the tap and fresh tea is poured on top. Sweet tea must continuously be added to replace any kombucha tapped from the vessel. This means adding sweet tea in to replenish your vessel every time you tap it.  Brewing time for CB can be anywhere between as 4 to 25 days. Over time the starter will become too strong, the SCOBY too big and the kombucha will be too sour. At this point a good deal of maintenance goes in to trimming the SCOBY, cleaning the vessel and spigot and then restarting the brew.

Now that we’ve got the terminology out of the way, here’s 3 reasons why we prefer batch brewing:

  1. Consistent Taste: Homemade batch brewed kombucha is consistently delicious and fizzy. There is a specific process that begins on day 1 and ends around day 10. You have regular control over the culture and environment. CB has a tendency to produce a more vinegary kombucha because of the big SCOBY and large quantity of strong starter liquid.
  2. Cost: Getting set up with a BB system we sell in our kombucha kits is less expensive than to getting set up for CB. The YEABUCHA kits range between $50 - $80 dollars and include everything you need to brew kombucha and continue for life. With CB the larger vessel is often more costly and finding a plastic-free spigot can be challenging. Plastic is a petroleum based product, so even if it is BPA- free, it is still made of chemicals that can leach into your kombucha if left for extended periods of time. CB also has a higher cost over time as it requires more tea and sugar than BB needs.
  3. Caffeine & Sugar: BB ferments for a set period of time that allows you to ensure there is little to no caffeine or sugar in the kombucha when you drink it. During CB you regularly add sweet tea to the culture and cannot be sure that the caffeine and cane sugar have been completely fermented. A common practice of CB is called drink a cup, add a cup. In this scenario it is likely that you are getting more caffeine and sugar in your glass than you ever would with BB, and that matters to us!

While it has been said that CB takes less time and is lower maintenance— we’ve found the opposite to be true! We have simplified the batch brewing process to make it easy, fast and convenient. You can’t beat 20 minutes a week that gives you consistently delicious homemade kombucha! Ready to get started? Pick up your kombucha brew kit today!

    Hi Glenda, the YEABCHA method speaks to only using a 1 gallon brew jar. If you are looking for the best brew kit out there, ours feature everything you need to start and keep brewing for life, along with a simple, 3 step guide to brew, flavor and bottle your kombucha. Cheers!

    Hi. I’m about to start my first batch ever. Is there a reason not to use a 2 gallon jar for a batch that will fill only half of the jar, besides being awkward? Thanks.

    Great article
    I am a batch brewer.
    Things I want to know are:
    How to make Kombucha more alcoholic,
    How to sell it for a lot of money.

    I have been batch brewing in a half gallon jar (m single, small apt ;-),, I’m on my 3rd batch and all is well. I am thinking about switching to a 1.5 gal glass container with a spigot. I think you’re making the CB more complicated then it needs to be,,, why not treat it like a BB and when the tea is ready, give it a stir, then bottle up all of the tea using the spigot down to the spigot level (wouldn’t this be more convenient?). Separate the old Scoby out, leave the new one so that it doesn’t get too thick and then refill for the next batch? you can completely empty the CB glass container twice or so each year to clean it if you feel it need to be. How does this sound? It’s really the same as batch brewing w/o having to empty the jar out each time.

    Hi Kristin, Thanks for reaching out with your questions. We’d recommend taking a SCOBY and 2 cups of liquid from you continuous brew jar and using them to start a batch brew. We sell in our shop a kit called the Everything but the SCOBY Kit which includes everything you need to start brewing a batch brew kombucha, minus the SCOBY (which you’ve already got!). I​f you are interested in going this route, we can guide you through the process of trimming your SCOBYs and starting a batch brew! ​
