Kombucha is a fermented drink made with tea, sugar, bacteria, and yeast. Although it is sometimes referred to as mushroom tea, kombucha is not made from mushrooms, does not contain any mushrooms, and is not technically a mushroom tea. The confusion likely stems from the fact that the bacteria and yeast culture used to ferment kombucha, known as SCOBY (Symbiotic Culture of Bacteria and Yeast), can resemble a mushroom in appearance, with its circular shape and brown or tan colour.

Kombucha is not made from mushrooms
Kombucha is a fermented drink made with tea, sugar, bacteria and yeast. Although it is sometimes referred to as "mushroom tea", kombucha is not made from mushrooms, does not contain any mushrooms, and is not technically "mushroom tea".
The confusion around kombucha and mushrooms is due to the fact that the SCOBY (Symbiotic Culture of Bacteria and Yeast) used to ferment kombucha resembles a mushroom with its circular shape and brown and tan colour. The yeast in kombucha also belongs to the same kingdom as mushrooms, the fungi kingdom. However, it is important to note that not all fungi are mushrooms, and yeast is not the same as a mushroom.
The kombucha SCOBY is a colony of bacteria and yeast that live in symbiosis. It is the starter culture that allows the fermentation of kombucha to begin. The SCOBY can have different shapes and colours, ranging from creamy white to dark brown, depending on the type of tea used and its age. It absorbs the colour of the ingredients like a sponge.
Kombucha is made by adding the SCOBY colony to sugar and tea, and allowing the mixture to ferment. This results in a liquid that contains vinegar, B vitamins, and other chemical compounds. While some proponents claim that kombucha tea has various health benefits, these claims are not backed by scientific evidence.

The SCOBY (Symbiotic Culture of Bacteria and Yeast) resembles a mushroom
Kombucha is a fermented drink made with tea, sugar, bacteria, and yeast. It is produced by the symbiotic fermentation of sugared tea using a symbiotic culture of bacteria and yeast (SCOBY). While kombucha is commonly referred to as "mushroom tea", it does not contain mushrooms and is not made with mushrooms. The confusion likely arises because the SCOBY (Symbiotic Culture of Bacteria and Yeast) resembles a mushroom with its circular shape and brown and tan colour.
The SCOBY is a living culture that ferments the sweet tea, turning it into bitter kombucha by consuming the sugar and caffeine in the tea and producing alcohol, acids, and carbon dioxide. The microbial populations in a SCOBY vary, but the yeast component generally includes Saccharomyces cerevisiae, while the bacterial component almost always includes Gluconacetobacter xylinus, which ferments the yeast-produced alcohols into acetic acid and other acids.
The SCOBY is also sometimes referred to as the "mother", with the new SCOBY produced in each brewing cycle called the "baby". This new growth, or "baby", appears on top of the original SCOBY, and its presence indicates the health of the kombucha ferment and brew.
The gelatinous pellicle that forms on the surface of fermenting kombucha is the kombucha SCOBY, which can have different shapes and colours depending on the type of tea used and the age of the SCOBY. The SCOBY is a colony of bacteria and yeast that live in symbiosis, and it is this culture that allows the fermentation of kombucha to begin.
While the SCOBY may resemble a mushroom, the only other association kombucha has with mushrooms is that its yeast belongs to the same kingdom, the fungi kingdom. However, not all fungi are mushrooms, so yeast and mushrooms are not the same thing.

Kombucha is a fermented drink made with tea, sugar, bacteria and yeast
Kombucha is a fermented drink made from tea, sugar, bacteria, and yeast. It is produced by fermenting sugared tea using a symbiotic culture of bacteria and yeast (SCOBY), commonly called a "mother" or "mushroom". The name "SCOBY" is an acronym for "Symbiotic Colony Of Bacteria and Yeast".
Kombucha is often referred to as "mushroom tea", and the bacteria culture used to ferment it is sometimes called "the mushroom". However, this is a misnomer; kombucha is not made with mushrooms and does not contain any mushrooms. The association with mushrooms likely arises from the visual resemblance of the SCOBY to a mushroom, with its circular shape and brown or tan colour. Additionally, the yeast in kombucha belongs to the same kingdom as mushrooms, the fungi kingdom, which may contribute to the association.
To make kombucha, a SCOBY is added to sugared tea, and the mixture is allowed to ferment. The resulting liquid contains vinegar, B vitamins, and other chemical compounds. Commercial kombucha often includes added flavourings such as juice, spices, or fruit. The drink has gained popularity due to its flavour and purported health benefits, such as improved digestion, gut health, and detoxification. However, it is important to note that the claimed health benefits of kombucha are not currently supported by scientific evidence, and there have been reports of adverse effects in some drinkers.
The process of making kombucha involves specific steps and considerations to ensure a safe and desirable end product. Homemade kombucha, in particular, carries a risk of contamination due to non-sterile conditions. When brewing kombucha, it is crucial to monitor the growth of the SCOBY, which typically produces a baby mushroom during each brewing cycle. Proper fermentation results in a pH level below 3.9, which effectively kills most human pathogens. However, if there are any doubts about the quality of the kombucha, it is recommended to discard it.

The beverage has caused rare adverse effects, possibly due to contamination during home preparation
Kombucha is a fermented drink made with tea, sugar, bacteria, and yeast. Although it is sometimes referred to as kombucha mushroom tea, kombucha is not a mushroom—it is a colony of bacteria and yeast. The colony is added to sugar and tea, and the mixture is allowed to ferment. The resulting liquid contains vinegar, B vitamins, and several other chemical compounds.
Kombucha is generally considered safe from a food safety perspective if it is made, handled, and stored properly. However, it has been associated with rare adverse effects, which may be due to contamination during home preparation.
Kombucha is often brewed at home under non-sterile conditions, making contamination likely. Contamination can occur from other microbes, containers, or the environment. For example, porous pots or resins and glazes that contain lead or other contaminants may leech into the kombucha during brewing. Antique stoneware jars can also contain lead, which can leech into the tea due to the acids in the tea. To avoid contamination, it is recommended to use clean equipment and follow basic hygiene practices, such as having clean hands and work surfaces, sterilizing containers and utensils, and using only boiled water to make the tea.
In addition to contamination, other factors such as over-fermentation or excess consumption may also contribute to the possible side effects of kombucha. Some people may experience digestive upset, gas, nausea, vomiting, or allergic reactions such as shortness of breath and tightness of the throat after consuming kombucha. People with compromised immune systems, heavy alcohol drinkers, and pregnant women may be more susceptible to certain side effects, such as lactic acidosis, which is an accumulation of acid in the blood.
Therefore, while kombucha may offer potential health benefits when consumed in moderate amounts, it is important to be aware of the potential hazards and follow recommended practices to prevent them.

Kombucha is now homebrewed globally, and also sold commercially
Kombucha is a fermented drink made with tea, sugar, bacteria and yeast. Although it is sometimes referred to as kombucha mushroom tea, kombucha is not a mushroom but a colony of bacteria and yeast. The kombucha culture, or SCOBY, is commonly called a "mother" or "mushroom", but this is simply because it resembles a mushroom or a large seaweed. The kombucha scoby can have different shapes and colours, ranging from creamy white to dark brown, depending on the type of tea used and the age of the scoby.
Kombucha is now a global phenomenon, with a market worth of approximately US$1.7 billion as of 2019. It is produced by the symbiotic fermentation of sugared tea using a symbiotic culture of bacteria and yeast (SCOBY). Kombucha can be prepared at home or commercially. It is made by dissolving sugar in non-chlorinated boiling water, steeping tea leaves in the hot sugar water, cooling the sweetened tea, and then adding the SCOBY culture. The tea is left to ferment for a period of up to 10 to 14 days at room temperature.
Commercially bottled kombucha became available in the late 1990s, and sales have been increasing ever since. In 2010, elevated alcohol levels were found in many bottled kombucha products, leading some retailers to pull the drinks from their shelves. In response, kombucha suppliers reformulated their products to have lower alcohol levels. By 2014, US sales of bottled kombucha were $400 million, $350 million of which was by Millennium Products, Inc. According to the market research firm Grand View Research, the global kombucha market size was US$1.67 billion as of 2019 and is expected to grow to US$9.7 billion by 2030.
The rise of commercial kombucha can be attributed to its association with gut health and its probiotic properties. With increasing awareness of the role of the gut microbiome in overall well-being, kombucha's natural probiotics and low sugar content have made it a popular choice among health-conscious consumers. Social media has also fueled the boom, with eye-catching branding, influencer endorsements, and hashtags like #kombuchalove turning this humble fermented tea into a lifestyle statement.
