A SCOBY is a symbiotic colony of bacteria and yeast
Kombucha is a fermented drink made from tea, sugar, and a SCOBY. The acronym SCOBY stands for "Symbiotic Colony Of Bacteria and Yeast". The kombucha SCOBY is what is known as a starter culture, as it allows the fermentation of the kombucha to begin. The bacteria and yeast in the SCOBY break down the tea's sugars and convert them into alcohol, carbon dioxide, and acids. The resultant kombucha contains numerous probiotics.
The appearance of a SCOBY can vary, but it is typically dense, round, rubbery, and opaque, with a mild vinegar-like smell. A 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. Like a sponge, it absorbs the colour of the ingredients. The microbial populations in a SCOBY vary, with the yeast component generally including Saccharomyces cerevisiae, along with other species. The bacterial component almost always includes Gluconacetobacter xylinus to oxidize yeast-produced alcohols to acetic acid (and other acids).
A new "baby" SCOBY is produced each time kombucha is made, and the SCOBY also helps turn sweet tea into more kombucha. It is similar to how sourdough bread bakers have a "mother" dough or sourdough "starter". That starter is a unique collection of yeasts that need to be "fed" with flour and water and is used to make more loaves of sourdough. A SCOBY is basically the means through which kombucha replicates itself.
The SCOBY is also a "house" that bacteria and yeast can live in and latch on to. The bacteria and yeast in the SCOBY work together in a symbiotic relationship, providing benefits for both. The symbiotic ingredients in the SCOBY are carefully chosen for their positive association and the fact that they will build on each other to create the desired reaction: in this case, the fermentation process and its benefits.

It is used to make kombucha
A SCOBY, or Symbiotic Culture of Bacteria and Yeast, is primarily used to make kombucha, a fermented tea beverage that has gained popularity for its potential health benefits. Kombucha has been consumed for centuries in various parts of the world and has become a trendy drink in recent years. Here's how a SCOBY plays a crucial role in the process of making kombucha:
The Kombucha-Making Process:
Kombucha is made by fermenting sweet tea with the help of a SCOBY. The process typically involves a few simple steps: First, you prepare a sweet tea base, usually black or green tea, by steeping tea in hot water and adding sugar. This sugary environment provides the fuel for the SCOBY to feed on. Once the tea has cooled, the SCOBY is added, often along with a small amount of previously fermented kombucha, known as a "starter liquid." The container is then covered to keep out contaminants and fruit flies, and the mixture is left to ferment.
The Role of the SCOBY:
During fermentation, the SCOBY breaks down the sugar in the tea, consuming and converting it into ethanol and organic acids, such as acetic acid and gluconic acid. These acids contribute to the sour, tangy flavor of kombucha. Additionally, the SCOBY produces B vitamins and various beneficial bacteria, which contribute to the potential health benefits associated with kombucha consumption. Over time, the SCOBY also forms a new layer on the surface of the liquid, which can be used to initiate subsequent batches of kombucha, creating a self-perpetuating culture.
Fermentation Time and Flavor Development:
The fermentation time can vary depending on the desired flavor and level of carbonation. Typically, kombucha is fermented for 7 to 14 days, but longer fermentation times can result in a more sour and carbonated beverage. The SCOBY continues to feed on the sugar and multiply, creating a more complex ecosystem of bacteria and yeast. This process also affects the flavor profile, as different bacteria and yeast strains contribute different flavors, ranging from fruity and floral to more acidic and vinegary.
Bottling and Second Fermentation:
Once the desired level of fermentation is reached, the kombucha is typically bottled and undergoes a second fermentation. This step is crucial for carbonation and further flavor development. During bottling, additional ingredients, such as fruit juices, herbs, or spices, can be added to infuse flavor into the kombucha. The sealed bottles are stored at room temperature for a few days to a week, allowing the carbonation to build up and the flavors to infuse.
Consuming the Kombucha:
After the second fermentation, the kombucha is chilled to halt the fermentation process and then consumed. The resulting beverage is slightly carbonated, tangy, and often slightly sweet, depending on the fermentation time and added flavorings. The presence of beneficial bacteria and organic acids contributes to the perceived health benefits of kombucha, although more scientific research is needed to confirm these effects.
In summary, a SCOBY is indeed used to make kombucha, and it plays a key role in transforming sweet tea into a tangy, slightly carbonated beverage with a unique flavor profile. The process of fermentation and the growth of the SCOBY culture are fascinating aspects of food science and traditional food preservation methods.

It is not a mushroom, but a mother culture
Kombucha is a fermented drink made from tea, sugar, and a SCOBY. A SCOBY is a symbiotic colony of bacteria and yeast. The acronym SCOBY stands for "Symbiotic Culture Of Bacteria and Yeast". It is also referred to as a "mother culture" or "mother".
Although the SCOBY is commonly called a "mushroom", it is not a mushroom. The name "mushroom" likely originated from the belief that the gelatinous film of kombucha resembled seaweed. The first known use of the word "kombucha" in the English language appeared in the British Chemical Abstracts in 1928. It is believed that English speakers may have confused the Japanese word "konbucha" with "kōcha kinoko" ('black tea mushroom'), which was popularized around 1975.
The appearance of a SCOBY can vary, but it is typically dense, round, rubbery, and opaque, with a mild vinegar-like smell. It is a cellulose mat that houses the bacteria and yeast cultures that turn sweet tea into kombucha. A new or "baby" SCOBY is produced each time kombucha is made, and the SCOBY also helps turn sweet tea into more kombucha. It is similar to how sourdough bread bakers have a "mother" dough or sourdough "starter". That starter is a unique collection of yeasts that need to be "fed" with flour and water and is used to make more loaves of sourdough.
The bacteria and yeast in the SCOBY work together to break down the sugars in the tea base of the kombucha. They convert them into alcohol, carbon dioxide, and acids. This process gives kombucha its tangy, fizzy taste. The SCOBY is an essential part of the fermentation process and also brings in the bacteria and fermentation factor that can help increase the health benefits of kombucha.

The bacteria and yeast in a SCOBY form a symbiotic relationship. The bacteria in a SCOBY almost always include acetic acid bacteria, and the yeast component generally includes Saccharomyces cerevisiae, along with other species. The bacteria in the SCOBY ferment the alcohols produced by the yeasts into acetic and other acids, increasing the acidity and limiting ethanol content. The yeast also helps break down the sugars included in the kombucha mixture.
The SCOBY is an essential ingredient in the fermentation and production of kombucha. It is the fermentation starter that kicks off kombucha fermentation. The SCOBY can be purchased online, in health food stores, or borrowed from a friend. It is also possible to grow your own SCOBY.

It can be reused as a starter for the next batch of kombucha
Kombucha is a fermented drink made from tea, sugar and a SCOBY. The SCOBY is a Symbiotic Colony Of Bacteria and Yeast. It is a rubbery, jelly-like mass that floats on the surface of the fermenting kombucha. The bacteria and yeast in the SCOBY break down the tea's sugars and convert them into alcohol, carbon dioxide and acids. This process gives kombucha its tangy, fizzy taste.
The SCOBY is also known as the "mother" or "mushroom". However, it is not actually a mushroom. The name "mushroom" is thought to come from the Japanese word "kōcha kinoko", meaning "black tea mushroom". The name "mushroom" may also have been used because the SCOBY can look like a mushroom, or because the gelatinous film of kombucha resembles seaweed.
A new "baby" SCOBY is produced each time you make kombucha. This new SCOBY can be separated from the "mother" SCOBY and used to brew a new batch of kombucha. The SCOBY can be reused as a starter for the next batch of kombucha. It continues to grow with each new batch and can be safely divided to share with others.
To brew a new batch of kombucha, you can use a 16oz bottle of raw, unflavoured kombucha and 1 cup (250ml) of green or black tea sweetened with 1-2 tablespoons (14-28g) of sugar. Combine the kombucha and cooled tea in a jar and cover tightly with a coffee filter or dishrag. Place the jar in a warm spot and let it ferment for up to 30 days. As the SCOBY forms, it will become thicker and less translucent. Once the SCOBY is about 1/4-inch (2/3cm) thick, it can be used to brew a new batch of kombucha.
