Frequently Asked Questions

What is kombucha ?
Kombucha is a fermented tea that has been consumed for over two millennia, growing out of Asia and Eastern Europe. Tea (white, green, oolong, black) is fermented with cane sugar to produce a slightly acidic-tasting, carbonated tea beverage.

What does Brew Dr. mean when it says it is “Craft Brewed”?
Our flavors are completely the product of what we do on the front-end of the brewing process. We have fine-tuned our recipes of high-quality organic teas, herbs, and dried fruits that are steeped together to make our flavor profiles. No altering is done after the fermentation is complete, making our kombucha truly 100% raw. It would be easier to make a large batch of ‘plain’ kombucha with a cheap tea and then flavor it after with juices or other flavoring agents, but we’re tea people and we believe in the art behind the flavor. If you love the taste of our kombucha compared to a lot of other kombuchas out there, this is the reason.

What are the “probiotics” in kombucha? And why are they good for us?

  • Two common types of yeast: Saccharomyces and Lactobacillus
  • Beneficial bacteria (acetic acetobacter) that together with the above yeasts help populate the gut with healthy flora to aid in digestion
  • Organic acids: acetic acid, lactic acid, propionic acid, glucuronic acid and gluconic acid. These organic acids are known to improve bioavailability of vitamins, prevent accumulation of heavy metals and insoluble oxalates, inhibit pathogenic bacteria, support joint health, modulate immunity and prevent cancer proliferation.

Is there caffeine in Brew Dr. Kombucha?
There are about 15 mg of caffeine in an entire 14 fl oz bottle of Brew Dr. That is a lot less than a cup of coffee (95 mg per 8 fl oz) and even green tea (25 mg per 8 fl oz). The reason there is so much less is that the fermentation process consumes the caffeine while creating the wonderful mix of probiotics in kombucha.

Has this kombucha been pasteurized (is it raw)?
Brew Dr. Kombucha is 100% raw. We wouldn’t dream of pasteurizing (cooking to death) all of those wonderful live and active probiotics.

Is sugar or juice added to Brew Dr. Kombucha?
The only time organic cane sugar is added is at the very beginning, when we sweeten the tea we brew. That sweetened tea is then put into a fermentation vessel along with a kombucha culture (often called a SCOBY – Symbiotic Colony of Bacteria and Yeast) and allowed to do its magic for about two weeks. After that, we do not add anything. No sugar, no juices. If you read the answer to the “craft brewed” question above then you know why we don’t need to alter our flavors after fermentation.

Is Brew Dr. Kombucha organic? How about non-GMO? Gluten Free?
Yes, yes and yes! All of our flavors are USDA Certified Organic. In fact, every ingredient in our entire brewery is certified organic. And you may already know this, but part of organic certification in the US is verification of non-GMO ingredients. So anytime you see the USDA Organic symbol on a product, you can rest assured it is 100% GMO free. And lastly, there are no gluten-risk ingredients at use in our kombucha brewery. All of our kombuchas are gluten free.

What’s the deal with alcohol in raw kombucha?
Good question. A by-product of any fermentation is ethanol. If not closely watched, kombucha fermentation can definitely lead to the creation of elevated levels of ethanol (up to perhaps 2.5% alcohol by volume). In order to remain a “non-alcoholic beverage,” any and all ready-to-drink beverages must remain below 0.5% alcohol by volume. This is no small task to accomplish. Brew Dr. Kombucha developed its method of controlling alcohol content in secret. We don’t openly share our method, but perhaps one day we will, at which time we will update this FAQ. We apologize for this bit of secrecy, but please believe us when we say we are very serious about making legitimate, traditional and authentic raw kombucha. We love our kombucha and we love that we can feel confident in serving it to customers such as children and on-duty medical professionals.
