How Is Coffee Kombucha Different To Kombucha?
Although both are considered kombucha for the fact they’re fermented using a SCOBY and share many similar characteristics, there are a few key differences to be aware of.
Coffee vs. Tea - Typically, kombucha is made using fermented tea, whereas coffee kombucha ferments brewed coffee.
Taste - Kombucha is a sweet fermented tea that has slight carbonation; kombucha coffee, on the other hand, is acidic, sour, and an acquired taste.
Brew Time - Coffee kombucha typically takes between 5-7 days to become ready, whereas fermented tea takes up to 14 days.
Rancidity - Coffee is an acidic beverage that can’t be left to ferment for long periods, as it can quickly turn rancid, and indigestible. In contrast, kombucha has been known to be left to ferment indefinitely, with the result being digestible vinegar. Keep an eye on your batch!

We’ll break it down for you to better understand where they’re coming from. Most related studies refer to the ingredient or chemical opposed to the batch being analyzed, therefore not comprehensively proven.

Kombucha And Fermenting With A SCOBY Health Benefits

Gut Health - When brewing kombucha, tea ferments leaving lots of bacteria and yeast in the brew. These bacteria and yeast are classed as probiotics, which are said to rebalance our gut. The gut has been linked to many different conditions, including IBS.
Weight Loss - This health claim is slightly loose and unproven. After research, the claim is when brewing coffee kombucha, there is a chemical produced. This chemical has been linked to being an appetite suppressant, which would help in reducing your calorie intake, in turn, aiding with weight loss.
Considerations Before Making Coffee Kombucha
pH - When brewing kombucha, it’s essential to keep the pH in a range between 2.5 - 4. When within this range, the growth of harmful bacteria is prevented, while the bacteria that encourage fermentation and probiotics can flourish. Coffee is an acidic beverage (low pH); therefore, you should not have to add extra starter tea or vinegar to get the batch brewing, be sure to check your pH before and during brewing.
Recommended Type Of Coffee - There are hundreds of variations of coffee, different bean varieties, different roasting methods creating an endless number of flavors. We would recommend using the Arabica bean, and one that has less bitter notes. Warning: It may require much experimenting to get the perfect batch!
Time - Typically, when brewing kombucha, you’ll ferment for 7-14 days. In contrast, coffee kombucha only needs 5-7 days. Coffee tends to over ferment and becomes rancid quite quickly. Make sure to monitor and test regularly.
SCOBY Color - Tea tends to keep the kombucha SCOBY as a yellow-orange color. However, when making coffee kombucha, you should expect the SCOBY to turn brown or black; the longer the coffee ferments, the darker the SCOBY goes.
How To Make Coffee Kombucha
Equipment Required To Brew
1 Gallon Mason Jar
1 Cup Measuring Cup (250ml)
pH Strips (Or Tester)
Ingredients Required To Brew
4 Cups Of Brewed Ground Coffee(4 cups = 950ml)
½ Cup Of Sugar
1 SCOBY With 1 Cup Of Starter Tea (250ml)
1. Sterilize all of your equipment with hot water (be careful)
2. Brew your coffee
3. Place your coffee in the jar and add the sugar
4. Stir until all of the sugar has dissolved
5. When room temperature place the SCOBY and starter tea in
6. Let settle then test the pH (look for between 2.5 - 4, if too high add more brewed coffee)
7. Find an area with a temperature between 68-74ºF (20-23ºC)
8. Leave for , test daily
9. Remove the SCOBY, strain the liquid, bottle
When bottling the coffee kombucha, you can add infusions, which would enhance or complement the flavor of the brew. It would be suggested to test the infusions just before drinking, instead of flavoring the whole batch. This would avoid too many spoilt experiments!
Here are a few ideas that you can infuse your batch with:
Storing Coffee Kombucha
Coffee Kombucha can become rancid pretty quickly. To slow or stop this continual fermentation, you’ll need to store it in a very cold area. It would be best suggested to keep in your fridge and consume within a few days. The maximum you’d want to leave this before consuming is 5-7 days. After this, you risk the rancidity, taste, and quality of your batch.
Another alternative would be to freeze your coffee kombucha. Freezing is the process of reducing the coffee kombucha’s temperature for it to become a solid. Coffee kombucha would need to be flash-frozen to preserve the bacteria. Flash freezing is when the temperature is reduced rapidly to make the beverage frozen. In contrast, slow freezing is when you add something to the freezer; this risks killing the bacteria during the slow freeze process.
How Much Caffeine Is In Coffee Kombucha?
We could not find any commercial brands’ information for the amount of caffeine in coffee kombucha. To get an accurate understanding, we would recommend to check the coffee brand that you’re using and then divide the amount you use by the number of servings to get a rough idea.
The fermentation process naturally starts to break down the caffeine in the coffee, which will slightly reduce the caffeine content. However, you should always check with the supplier if you’re caffeine sensitive.
Do I Use Tea When Making Coffee Kombucha?
When making coffee kombucha, you should not use tea. Instead of where you would typically start the batch by steeping tea bags, instead, you would brew your coffee before adding it to your jar.
Can You Add Coffee To Your Kombucha?
When brewing, you wouldn’t add coffee to your kombucha, as you’d start the batch with coffee. If, however, you’re looking to infuse your already fermented tea kombucha with coffee, you could, but we wouldn’t recommend it. The flavors would clash, leaving for a bad tasting flavor.
Does Coffee Kombucha Make You Poop?
Potentially yes. Coffee is almost famous for the fact that it causes bowel motions. It’s thought that either the caffeine, warm fluid, or a chemical within coffee is responsible for it to trigger the need to go to the toilet.
Is It Safe To Drink Coffee Kombucha Every Day?
When considering how much kombucha to drink, we would suggest sticking to the suggested amount of 8oz (240ml) serving per day. Although check with the brand you’re going to be drinking for if they suggest less, then always follow their advice.
How Much Alcohol In Coffee Kombucha?
It’s estimated between 0.5 - 3%. This is dependent on many factors, such as sugar content, the temperature of brewing, and SCOBY type. If you’re alcohol sensitive, it would be best suggested that you got an alcohol hydrometer to test the alcohol content. Also, to keep the temperature lower in the critical range to inhibit kombucha producing bacteria.
