What is kombucha?


This is the most common question we’re asked among new kombucha drinkers! Our kombucha is a bubbly delicious healthy drink that is 100% organic.

Kombucha is produced by fermenting sweet tea with a beneficial bacteria and yeast culture (SCOBY). It is a “living” beverage that is rich in probiotics and contains beneficial organic acids, B vitamins, minerals, enzymes, and antioxidants.

And it’s been around for a while! Kombucha has been referred to as an ancient elixir dating back to 220 BC in northeast China where it was widely consumed for its detoxifying and energizing abilities.

What are some health benefits of drinking kombucha?


Here’s just a few!

  • Boosts energy with enzymes and B vitamins

  • Aids in weight loss with acetic acid and polyphenols

  • Strengthens the immune system with anti-oxidants

  • Detoxifies the body with gluconic acid and probiotics

  • Improves the digestive system with probiotics

  • Eases joint pain and helps prevent arthritis with glucosamines

What does AFK mean?

AFK is an acronym meaning “Away From Keyboard”. It’s a phrase or away status popular among computer and gaming geeks to let people know that they will be away from the computer for a while. AFK Craft Kombucha was founded by two full-time IT Professionals and when they aren’t at a terminal, they are AFK bringing you that delicious craft kombucha.

How much kombucha should I drink?

Everyone’s body is different! We recommend new kombucha drinkers start with 4-8 oz a couple times a day until your body is used to it. As your body becomes used to it, drink what you’re comfortable with. We know folks that drink 16oz a day and others that drink 64oz a day. Listen to your gut!

How long does kombucha last?

If you love our kombucha as much as we do, then probably not very long ;)

Kombucha doesn’t actually go bad! It will last for months in your refrigerator where it will continue to ferment at a very slow rate. Because it is a fermented beverage with a low pH, it has an extremely long shelf life!

Once opened, we recommend drinking within 5-7 days if you prefer that bubbly/fizzyness of the carbonation. As time goes on it may become a little flat (which some people actually prefer).

By law, commercial kombucha brewers must have a “best before” date on their bottles, which is just an estimation for peak freshness or best taste. As kombucha ages, the taste of it has the potential to change.

Do I need to keep my kombucha refrigerated?

Yes. To maintain the intended taste and integrity, it should be kept refrigerated at all times. It will not go bad, but kombucha will continue to ferment at room temperature. As non-refrigerated kombucha ages, the alcohol content and bottle pressure will also increase, and the beverage will become more tart and vinegary tasting.

Does kombucha contain alcohol?

Our kombucha (and most kombucha) that is sold as a non-alcoholic beverage contains trace amounts of alcohol (LESS THAN 0.5%), which is less than fresh squeezed orange juice, a ripe banana, or even bread (and anything made with baker’s yeast for that matter)! However, kombucha can continue to ferment into a slightly higher alcohol content if not refrigerated properly, which is why it is printed on our bottles to keep the beverage refrigerated at all times.

Where can I find nutritional facts about your products?

We haven’t ordered a full lab workup yet for a nutritional facts panel, but we’re working on that behind the scenes. It will vary from recipe to recipe depending on flavor, but just to give you an idea here is a general approximation on the nutritional fact panel of raw kombucha per 8 oz serving.

How much caffeine is in kombucha?

Caffeine is inherited from the tea and the amount will differ depending on the type of tea used. Caffeine is essential for producing kombucha, but most of it is metabolized during the fermentation process. We haven’t had a full nutritional panel done on our kombucha as of yet (that is coming very soon), but as a general estimate, 8oz of raw kombucha contains the caffeine equivalent of approximately two sips of coffee. The exception to this is our Perk flavor of kombucha, which is co-fermented with fresh ground coffee beans and in that brew the caffeine content is going to be a bit higher.

What’s that floating around in my kombucha?

It’s not uncommon to see floating yeast strands (we call them beasties!) or yeast sediment at the bottom of the bottle. It’s all beneficial culture and it’s perfectly fine to consume! In fact, it’s healthy for you! It’s also a telltale sign that you’re drinking AUTHENTIC RAW kombucha that is healthy, alive, and well — and not just some manufactured juiced down vinegar (yuck).

Sometimes you may even see a little gelatinous yeasty pancake looking thing floating around. This is actually a baby SCOBY (Symbiotic Culture of Bacteria and Yeast) and it is basically a super concentrated semi-solid form of kombucha! The SCOBY’s primary job is to ferment the sweet tea, converting caffeine, tannins, and sugars into that delicious effervescent and tangy goodness that we love and know as kombucha!

Can I shake up the sediment at the bottom of my bottle?

Swirl, don’t shake! The sediment at the bottom of your bottle is naturally occurring yeasts that settle as the kombucha sits. It is like any other carbonated beverage where if you shake and then open, it will fizz up and spill out. It is perfectly okay to gently swirl the bottle to mix all that goodness back in!

Why does this batch taste slightly different from the last batch?

Although we strive to be as consistent as possible by using standardized ingredients, regulating fermentation temperatures, following strict brewing and fermentation SOPs, practicing rigorous monitoring, testing, and documentation on every batch — there is a possibility of a slight variance from batch-to-batch because every batch is truly unique!

  • We take pride in the fact that we’re bringing you home-brewed kombucha that is as authenticate as it gets!

  • We don’t cut or dilute our batches to reach a specific target pH reading.

  • We don’t post-flavor or do ANY form of secondary fermentation, which often hides variance to establish false consistency.

  • We don’t put our final product through any filtration process.

  • Every keg that we put out is technically a different micro-batch so there will always be that possibility of a slight variance in the final taste because no two batches should ever be EXACTLY the same!

You may never notice a variance from batch-to-batch (and we hope that you don’t), but if you do, you now know that it’s not a fault or from lack of trying, but rather a byproduct of bringing you the most authentic CRAFT KOMBUCHA that we possibly can.

Is kombucha safe to consume while pregnant or nursing?

Although the risk is likely limited, this can be a controversial topic because kombucha is unpasteurized, contains small amounts of caffeine (most of which is metabolized during the fermentation process), and contains trace amounts of alcohol (ours is less than 0.5%). According to the FDA, less than 0.5% ABV is considered to be non-alcoholic, which believe it or not is actually less than a fresh squeezed orange, a ripe banana, and even bread (or other goods that contain baker's yeast).

We are not aware of any large scale studies or extensive research on nursing while consuming kombucha though, so if you feel that you should consult a professional, we would recommend reaching out to your pediatrician.

How are your various flavors inspired?

Our kombucha is fermented with select organic ingredients to provide flavor variety and additional health focused benefits. This means that our flavors are infused into the brew before it even becomes kombucha. We do not brew a standard base kombucha and then post-flavor it after primary fermentation. We do not do a secondary fermentation. All of our flavor offerings are uniquely brewed from the very beginning, which is why all of our flavors taste totally different from each other.

Many factors go into why we craft specific flavors using our chosen co-fermntables, but the two main reasons are; 1.) flavor variety - not everyone has the same taste pallet, 2) additional health focused benefits - all of our co-fermentables have their own health benefits.

You may have noticed that our bottles have REDUCE ∙ REUSE ∙ REFILL printed on them! We believe a fill station pricing model is the most sustainable way of putting our kombucha in your hands at the most affordable price possible. A refillable model produces less waste and reduces a significant amount of expense, allowing us to pass those savings directly on to our consumers.

When you purchase or acquire one of our bottles, they can be filled at any of our fill stations, which are deployed at various locations. Refills reduce your cost verses buying a brand new bottle. Please bring only clean vessels to fill. You can also exchange your bottles or sell them back as well where they will be put through our sterilization process for reuse.

Do you offer wholesale pricing?

Yes, we offer cornelius kegs (5 gallons) at wholesale price + keg deposit. Please reach out to us at for information on pricing and availability.
