Kombucha is a fermented drink made from tea, sugar, bacteria, and yeast. The bacteria and yeast culture that ferments the tea is called a SCOBY, which stands for Symbiotic Culture of Bacteria and Yeast. While kombucha is commonly referred to as mushroom tea, it does not contain any mushrooms and is not made with mushrooms. The association with mushrooms likely comes from the fact that SCOBYs can sometimes resemble mushrooms in appearance, with their circular shape and brown and tan colour. Additionally, the yeast in kombucha belongs to the same kingdom as mushrooms, the fungi kingdom. However, not all fungi are mushrooms, so it is inaccurate to refer to kombucha as a mushroom.

Kombucha is not a mushroom, but a SCOBY
Kombucha is a fermented drink that has become quite popular in recent years due to its taste and purported health benefits. It is produced by fermenting sugared tea using a symbiotic culture of bacteria and yeast, commonly called a "mother" or "mushroom".
Despite its common name, kombucha is not a mushroom. The confusion arises because the culture used to ferment kombucha, known as SCOBY (Symbiotic Colony Of Bacteria and Yeast), can sometimes resemble a mushroom in appearance, 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, from a biological perspective, a kombucha SCOBY is no more a mushroom than it is a bird.
The SCOBY is a living culture that ferments the sweet tea into kombucha by consuming the sugar and caffeine in the tea and producing alcohol, acids, and carbon dioxide. The bacteria in the SCOBY produce bacterial cellulose, which gives the SCOBY its physical structure. The thickness of the SCOBY is inversely related to the amount of gluconic acid produced. The movement of the SCOBY, which may sink, float, or go on its side, is due to the activity of the yeasts and the carbonation they produce.
Kombucha can be easily produced at home by using a kombucha fungus or SCOBY in a finished kombucha drink as a culture medium. A new kombucha SCOBY will develop within a few days, covering the whole surface of the tea and becoming thicker over time.

SCOBY is an acronym for Symbiotic Culture of Bacteria and Yeast
Kombucha is a sweetened black tea drink that is fermented and effervescent. It is made using a symbiotic culture of bacteria and yeast, commonly referred to as a SCOBY.
SCOBY is indeed an acronym for Symbiotic Culture Of Bacteria and Yeast. The "symbiotic" in SCOBY refers to the relationship between the bacteria and yeast. The bacteria and yeast vie for domination. As the yeast population grows, it crowds out the bacteria. However, as the yeast population explodes, it runs out of oxygen. This forces the yeast to ferment to survive, and the alcohol by-product fuels the revival of the bacteria.
The kombucha SCOBY is often called a "mushroom", "tea fungus", or "mother". This is because the SCOBY resembles a mushroom with its circular shape and brown and tan colour. However, it is important to note that kombucha is not a mushroom. The only real association kombucha has with mushrooms is that its yeast belongs to the same kingdom as mushrooms, the fungi kingdom.
The kombucha SCOBY is a living culture that ferments the tea. It turns the kombucha from sweet tea into bitter and tasty booch by eating the sugar and caffeine in the tea and producing alcohol, acids, and carbon dioxide. The SCOBY can have different shapes and colours, depending on the type of tea used and its age. It is usually 1/4 inch to 2 inches thick, has a jelly-like texture, and is disk or circular-shaped.

The yeast in SCOBY belongs to the Fungi kingdom, like mushrooms
Kombucha is a fermented drink made from tea, sugar, and a symbiotic culture of bacteria and yeast, commonly referred to as a SCOBY. The acronym SCOBY stands for Symbiotic Culture of Bacteria and Yeast. The yeast in SCOBY belongs to the Fungi kingdom, like mushrooms. However, it is important to note that kombucha is not a mushroom, and the SCOBY is not a type of mushroom, despite the common association and naming conventions.
The confusion around kombucha and mushrooms may arise from the fact that the SCOBY, a gelatinous pellicle that forms during the fermentation process, can visually resemble a mushroom. 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. The circular shape and brown or tan colour of the SCOBY are likely the most mushroom-like features. Additionally, the yeast in the SCOBY, which is responsible for the fermentation process, belongs to the Fungi kingdom, just like mushrooms.
From a biological perspective, the SCOBY is a symbiotic colony of bacteria and yeast species coexisting in a biofilm. The specific yeast species in the SCOBY can vary, but commonly include Saccharomyces cerevisiae. The bacterial component typically includes acetic acid bacteria such as Komagataeibacter xylinus (formerly known as Gluconacetobacter xylinus), which play a crucial role in converting yeast-produced alcohols into acetic and other acids.
The process of brewing kombucha with a SCOBY involves seeding sweet tea with a source of kombucha culture, which can be obtained from a previous batch of fermented kombucha tea or purchased from specialty stores. During fermentation, the bacteria and yeast in the SCOBY work together, with the bacteria intentionally limiting oxygen access to the yeast, forcing it into a fermentation stage. This results in the production of alcohol, acids, and carbon dioxide, transforming the sweet tea into kombucha.
While the yeast in the SCOBY shares the Fungi kingdom classification with mushrooms, it is important to clarify that the SCOBY itself is not a mushroom. This distinction is important to make, especially when considering the health aspects and benefits associated with consuming kombucha. While kombucha is often touted for its potential health advantages, such as improved digestion and gut health, these claims have limited scientific evidence supporting them. Additionally, it is essential to exercise caution when consuming homemade kombucha, as there have been rare instances of serious adverse effects possibly arising from contamination during preparation.

SCOBY can be dried and eaten as a snack
Kombucha is a beverage that can be produced at home using the Kombucha fungus or tea fungus, also known as a SCOBY. The acronym SCOBY stands for "Symbiotic Colony Of Bacteria and Yeast".
Despite its name, the Kombucha SCOBY is not a mushroom. It is a colony of bacteria and yeast that live in symbiosis. The gelatinous gel that forms on top of the brew during the fermentation process is referred to as a SCOBY or MOTHER.
While some people may be hesitant to consume SCOBYs, they can be dried and eaten as a snack. Here are some ways to prepare SCOBY snacks:
- Jerky: Cut the SCOBY into strips and toss them with your favourite spices and flavourings. You can use a dehydrator or place the strips on a parchment paper-lined sheet tray, cover them with a cloth, and leave them in an oven overnight with the pilot light on. You can also try this method with an oven that only goes down to 170°F by heating the oven and then turning it off before putting the strips in to dry.
- Frying: Cut the SCOBY into bite-sized pieces and mix them with chopped vegetables like tomato, cucumber, and carrots. Dip the pieces into a batter made of beaten egg and flour, or just the egg wash, and then into the flour. Fry in hot oil until golden and crispy. Sprinkle with salt for a savoury snack or with sugar and cinnamon for a sweet treat.
- Pickling: Cut the SCOBY into bite-sized pieces and mix them with chopped vegetables. Put them in a jar, pour in Kombucha to cover, and add salt and honey to taste.
- Smoothies and Fruit Leather: Blend the SCOBY with fruit to create a puree, then spread it out on parchment paper or dehydrator sheets and dry it out until no longer sticky. You can also add the SCOBY to one of your favourite smoothie recipes to help thicken it.
- Snack Balls: Combine the SCOBY puree with oats, nuts, dried fruit, and nut butter, then scoop into balls. You can make different variations like date balls, "cookie dough", or chocolate.
- Candy: Create SCOBY candy using sugar, honey, or maple syrup. There are several methods for making candy, including gummy bears and fruit leather.
These are just a few ideas for how to dry and eat SCOBYs as a snack. While some people may find the idea of consuming SCOBYs unappealing, others, including children, have enjoyed these creative and tasty ways to use this byproduct of the kombucha-making process.

SCOBY is used to make kombucha at home
Kombucha is a fermented drink that can be made at home. It is produced using a SCOBY, which stands for "symbiotic colony of bacteria and yeast". Despite its name, a SCOBY is not a mushroom, although it may resemble one. It is also referred to as the "mother" culture, as it kickstarts the fermentation process and produces new SCOBYs with each brewing cycle.
To make kombucha at home, you will need a SCOBY, which can be purchased or sourced from a friend who brews kombucha. It is important to ensure that the SCOBY is healthy and well-balanced, with a pleasant smell and good flavour. You can also grow your own SCOBY from a bottle of raw kombucha, although this takes longer and requires some trial and error.
Once you have a SCOBY, you will also need water, sugar, and black tea. The tea should be brewed and then cooled before the SCOBY and raw kombucha are added. The mixture is then covered and left to ferment at room temperature for 1 to 4 weeks. During this time, the SCOBY will feed on the sugar in the tea, producing a tangy and nuanced drink. The optimal temperature range for fermentation is between 75 and 85 degrees Fahrenheit.
It is important to maintain cleanliness when brewing kombucha, as bad bacteria can ruin the batch and potentially make you sick. Metal and plastic containers should be avoided, as metal can react with the acidic kombucha, and plastic can harbour harmful bacteria. If mould is spotted on the SCOBY or in the tea, the batch should be discarded.
After the initial fermentation, the kombucha can be flavoured with fruit and bottled in a sealed container for 2 to 4 days at room temperature to create carbonation. This process can be repeated to produce additional batches of kombucha, as the SCOBY will continue to grow and duplicate itself.
