What is kombucha?

Kombucha is a live, probiotic beverage filled with billions of probiotic bacteria drank for millennia to help assist with digestion and overall health.

How is Seattle Kombucha made?

Kombucha is made by fermenting sweetened tea with a specific set of kombucha bacteria and yeast for 7-30 days. During the fermentation, the kombucha bacteria and yeast transform the sugars and other components in the tea into a low sugar, unique tasting, probiotic beverage.

How should I store my Seattle Kombucha?

Authentic kombucha like Seattle Kombucha is a live, raw, probiotic product. Ideally, Seattle Kombucha needs to stay refrigerated between 34-38 degrees Fahrenheit until you are ready to drink it. If you are unable to access a refrigerator, keep the kombucha as cool as possible using a cooler or cooler bag filled with ice or freezer packs.

I accidentally left my Seattle Kombucha out. What do I do?

If your kombucha gets warm, and its been out for a while, don't open it. Return it to the fridge or a cold cooler as soon as possible. After it cools down, you can open it. Always take precaution when reopening a bottle that has been left out of refrigeration and then re-chilled.

Pro Tip: Place the bottle in a wide mouth glass or bowl larger than the bottle itself to capture any overspill in the case your kombucha fizzes over. This will minimize the mess and make sure your kombucha doesn't go to waste! You could also put a towel over the top when you are opening it in case it does fizz over a bit.

What happens if my kombucha is not refrigerated?

If your kombucha is left out of refrigeration and gets warm, if there is any sugar in the bottle, your kombucha will begin to ferment again and become more sour and change flavor as the yeast and bacteria consume the remaining sugar and turn it into kombucha, a little more alcohol and CO2 gas. The pressure inside the bottle will increase and may increase so high that the bottle fizzes all over the place when opened, or could even explode if left out for too long.

When kombucha is left out of the fridge and it continues to ferment, the flavor may change to be more sour and less sweet. It may also increase the carbonation and pressure inside the bottle. The fruitier and sweeter the kombucha, the faster the flavor will usually change. The more earthy or sour the flavor, the less it will change by being left out of refrigeration.

WARNING! If authentic, unpasteurized, live kombucha is left out too long, (if there is enough sugar in the bottle) the carbonation and the pressure inside the bottle may become too high causing the bottle to fizz all over the place when you open it, or the bottle may even explode. SO... BE VERY CAREFUL IF YOU ARE GOING TO LEAVE YOUR KOMBUCHA OUT OF THE FRIDGE! Or just keep it in the fridge until you are ready to drink it.

Can I drink kombucha warm?

Yes. Some flavors taste great when served warm, including our Lady Grey, Ginger Gold and Roasted Mate'. You could, like a wine, take it out of the fridge and open it several minutes or hours before serving it to let it breathe and warm up. Feel free to experiment with letting your bottles warm up a bit before consuming them to see if you like it better that way.

Also, sometimes people find cold, carbonated beverages difficult to drink and prefer them a little warmer.

If you are going to leave a bottle or two out to experiment with drinking it warm, or you want to let the fermentation continue because you prefer your kombucha less sweet, just make sure you open the bottle and keep the cap loose in order to prevent the pressure from getting too high.


I like the taste of Seattle Kombucha, but it's too fizzy. What can I do to reduce the carbonation?

We are glad you love the taste. To reduce carbonation, we recommend transferring the bottle of kombucha to a glass. If that doesn't reduce it enough, you can stir the kombucha to remove the carbonation. You can transfer it back to the bottle if you would prefer to drink it from the bottle. 

You can also open the cap and leave it off or retighten it loosely so that the carbonation reduces. Just make sure to retighten the cap once you've achieved the level of carbonation you are looking for to lock in the right amount.

I like the taste of Seattle Kombucha, but it's not fizzy enough. What can I do to increase the carbonation?

You can leave it out of the fridge overnight then return it to the fridge in the morning. Overnight it will begin to re-ferment, creating more CO2 carbonation inside the bottle. The side effect of this is that the kombucha may taste less sweet and have slightly more alcohol. If overnight is not long enough, you can try leaving it out for 1-2 days before returning it to the fridge.

Is there alcohol in Seattle Kombucha?

Yes. But very little. Seattle Kombucha contains less than 0.5% alcohol, which categorizes it as a non-alcoholic beverage. Because kombucha is a fermented beverage, it naturally contains a trace amount of alcohol as the yeast converts sugar to alcohol, water and CO2. One of the reasons that kombucha has so little alcohol compared to beer or wine is that the bacteria present in kombucha convert some of the alcohol to beneficial acids like acetic acid, gluconic acid and glucaronic acid.

Kombucha is safe for most children and adults to drink any time of the day. 

If you are avoiding alcohol due to pregnancy, allergies, sensitivities, or religious beliefs, you should not drink Seattle Kombucha or any other authentic kombucha. 

I want to order Seattle Kombucha kegs for my event or office. How many people will a keg serve?

Our kegs are 5 gallons each and serve 50 12oz servings. If you prefer bottles, we can offer our 12oz bottles at wholesale prices if you buy 50 or more at a time. Another benefit of buying bottles instead of kegs is that you can mix and match the flavors!
