Kombucha Beer: Alcohol Content, Benefits & Recipe

In the age of a renewed interest in the infamous and ancient kombucha beverage, why not take it a step further and make it the way most people like their drinks: with alcohol! 

Kombucha beer (or “hard” kombucha) is kombucha tea that has a minimum alcohol level above 0.5% — but it can get up to 7%. There are two different ways to accomplish this: the first is through extended natural fermentation, the second is through adding additional alcoholic ingredients. 

If you want to find out more about kombucha beer, travel with us below and we’ll discuss the ins and outs of kombucha beer (and kombucha), how they are made, and how to make them for yourself.

How Kombucha Beer Is Made

As we said, there’s a few different ways to make kombucha beer. Well, there are two — but there are more and less complicated versions of those two. We’ll start with the first: the natural artisan method

Natural Artisan Method

All the natural artisan method really is making kombucha that sits out a little longer than the normal fermenting period, which produces more alcohol as a result. Alcohol is a natural and necessary byproduct of kombucha and, though kombucha companies often modify their kombucha alcohol levels for general consumption, there will always be some alcohol in there. 

The easiest way to make natural kombucha beer is to let it ferment longer. The fermentation process is what makes kombucha alcoholic in the first place, so it’s only natural that a longer fermentation period would equal a higher concentration of alcohol. But it won’t be that alcoholic. Probably a few percent at best.

But how long should you let it sit out for? We’ll get to more of that below, but the short answer is: it depends on how alcoholic you want it. Kombucha can be initially brewed for about a week, but you can make it sit for upwards of a month to get it way more fermented and have a higher level of alcohol. 

Collaboration Method

Now, nobody liked group projects in school unless you were partnered with a really smart kid who did all the work (unless you were that smart kid!). But, as you find in the corporate area, and hopefully in a couple of your group projects, there are one or two collaborations that are just right

This is exactly the case when normal, low-alcoholic kombucha tea partners with an external alcohol. Now that’s a group project I want to be part of! For your kombucha beer — if you want to stick to beer — you can literally go pick up a 12 pack and a few bottles of kombucha, and mix them together (slowly because kombucha is pretty carbonated and reactive) and then you are ready to go. 

The bitter flavors of alcohol mix well with the somewhat bitter, but sweet and fruity taste of the kombucha. Kombucha beer is basically Mike’s Hard Lemonade with a little more sophistication — and less sugar! 

What Do You Mean “Make It”?

If you haven’t figured it out yet, you don’t have to make a single thing for kombucha beer if you don’t want to. The collaboration method takes perfect care of that.

But, if you are a stubborn do-it-yourself artisan, there are even more options for you. Before we get into the best way to make kombucha beer (hint: it’s like actual beer brewing brewing!), we have to discuss how real kombucha is made in the first place. For you artisans out there, the rest of the article is for you. 

How Do You Make Kombucha Tea into Kombucha Beer? 

First off, saying “kombucha tea” is a bit repetitive, because kombucha is tea that has been fermented. If that’s any hint, tea is the first ingredient needed to make kombucha. Here’s the short list of the needed ingredients: tea, sugar, SCOBY, and a starter.

  • Tea: The most common tea used to make kombucha is black tea. But others, such as green and oolong tea (but not herbal teas because they are oily!) can be great as well.
  • Sugar: You need real sugar, and a good portion of it; the reason for this lies in the next ingredient.
  • SCOBY: A SCOBY (or “symbiotic culture of bacteria and yeast”, if you prefer the mouthful version) is the heart and soul of the kombucha. Though the slimy pancake-thing does not look like a hero, it is. SCOBY is the single ingredient that transforms boring old tea (sorry tea lovers) into the fermented bliss of kombucha. 
  • Starter: A “starter” is simply kombucha that is already made or bought. Adding a little starter excels and quickens the fermenting process. Though it is not technically absolutely necessary, it almost is.  

After making the kombucha tea and finishing the second fermentation, its time to turn it into kombucha beer. 

How Alcoholic Do You Want It?

Your first thought might be: how Alcoholic can you get it? As we said, letting the second fermentation of your kombucha sit longer than usual will get it more alcoholic. Just remember, using this method will not “spike” the kombucha in the normal use of the word, but a longer fermentation should give it a little kick. 

Keep in mind that the longer the kombucha ferments, the less sweet it will be because the SCOBY is always consuming the sugar. So if you make the kombucha more alcoholic through this method, it will be less sweet. 

So, while this method will make it a little more alcoholic, in order to make the kombucha truly competitive with — say —  beer, you will need to do something different. Some may call it beerer-izing your kombucha; others may call it making a true, artisan kombucha beer. Either, put on your beer brewing hats.

Making Real Kombucha Beer

In order to start making kombucha beer entirely from scratch, you have to think like a beer brewer. This includes thoughts like yeast, and maybe hops, and other beer flavorings. The process of turning kombucha into a beer-like alcohol level involves only one extra step in the fermenting process, right in between the original first and second fermentation.

  • As we discussed above, the first step in making kombucha is combining all the ingredients, and letting the tea go through its first fermentation for about a week. 
  • But, for making the beer, this additional fermentation will  occur right after the initial one. After the first week or so after the kombucha has been sitting, you take yeast (not bread yeast, but yeast sold in brew shops), stir it in on the stove with warm water and sugar and, after it is cooled, add it into the gallon of kombucha beer. 

Once you stir it in with the kombucha — and add hops or whatever flavorings you want — use a jar with an airlock, or a tight lid, to let you kombucha sit and turn alcoholic. This process will also take about a week.  

You should take out the flavorings after 2-3 days. During the week, taste your kombucha beer through the days until it has the perfect tang and alcohol level for you.

  • The third step is the original second step — the final fermentation. After the kombucha has reached the desired alcoholic level, put it again in a tight bottle and let it sit for about a week. After this the fermentation will be finished, and the sugar that was added through the yeast and originally in the first fermentation will be adequately processed by the SCOBY.
  • After this, you can now refrigerate your kombucha beer and enjoy!

Basically the process of making kombucha beer from scratch is doing three total fermentations, instead of two. This will take, on average, around 3 weeks. This is why it’s a great idea to make at least a gallon of kombucha brew, otherwise you will run out while trying to make another batch. 

Here are some recipes (12) to consult if you want some other ideas of what flavors to add, or a visual aid to go along with it. Happy brewing kombucha makers! 


  • Hi, I'm Marvin! In early 2019 I started fermenting sauerkraut, kefir, and kombucha and noticed the incredible health benefits that came with it. I was less irritated, had fewer allergies and my skin got better. I started this blog to share how fermented foods have helped me and how simple they are to prepare! Look around and see what speaks to you and all the best on your fermentation journey!
