Water kefir, also known as tibicos, sugar kefir grains, Japanese water crystals, or rice mushroom, is a fermented drink made with water and water kefir grains. It is a probiotic beverage that is often consumed as an alternative to milk-based drinks or tea-cultured products. Water kefir grains are made up of a symbiotic culture of bacteria and yeast, which feed off the sugar in the water to produce lactic acid, ethanol, and carbon dioxide, resulting in a fizzy and probiotic-rich drink. While water kefir is sometimes referred to as rice mushroom, it is important to note that it does not actually form mushrooms. Rather, the term mushroom may be used to describe the grains used in the fermentation process, which are small gelatinous granules containing various strains of beneficial microorganisms.

What You'll Learn
Water kefir, also known as tibicos
Water kefir grains, also known as tibicos, sugar kefir grains, Japanese water crystals, and California bees, are made up of a symbiotic culture of bacteria and yeast. This mixture of yeast and bacteria ferments in a sugary liquid, feeding off the sugar to produce lactic acid, ethanol, and carbon dioxide gas, which carbonates the drink. The bacteria Lactobacillus brevis is responsible for the production of the dextran polysaccharide that forms the "grains".
Water kefir can be made at home with water kefir grains and a sugary liquid such as coconut water, fruit juice, or sugar mixed with water. It is important to maintain a clean environment and sterilize equipment to prevent the wrong types of bacteria from contaminating the liquid.
Kefir is often associated with mushrooms, and milk kefir mushrooms are well-known for their health benefits. However, water kefir does not form mushrooms. Water kefir grains are small gelatinous granules that contain microorganisms, giving them a different appearance and microbial composition from milk kefir grains.
Incorporating water kefir into one's diet may offer potential health benefits, but it is advisable to consult a doctor first for those with weakened immune systems.

The probiotic properties of water kefir
Water kefir, also known as tibicos, is a traditional fermented drink made with water and water kefir grains. It is often consumed as an alternative to milk-based probiotic drinks, particularly by those who follow a plant-based or vegan diet, or those who are allergic to milk proteins or lactose intolerant.
Water kefir is a rich source of probiotics, containing a diverse range of beneficial bacteria and yeast. The grains are a natural symbiotic culture of bacteria and yeast, which work to ferment water and nut milks. The bacteria present in water kefir include Lactobacillus brevis, Lactobacillus, Lactococcus, Streptococcus, and Leuconostoc. Water kefir also contains strains of yeast that can metabolize lactose, such as Kluyveromyces marxianus, Kluyveromyces lactis, and Saccharomyces fragilis.
The probiotic content of water kefir has been linked to several health benefits. Firstly, it may help boost immune function, potentially aiding in cancer prevention. Test-tube studies have shown that kefir extract can help decrease the growth of certain types of cancer cells, including breast cancer, colon cancer, and blood cancer. Additionally, water kefir may help reduce the risk of intestinal infections, prevent the recurrence of urinary tract infections in women, and keep respiratory infections at bay.
Water kefir is also a good source of vitamins and minerals. The beneficial bacteria in water kefir produce vitamins such as B12, which is crucial for brain and heart health. The fermentation process also results in the formation of beneficial digestive acids.
Overall, water kefir is a probiotic-rich beverage that offers a wide range of potential health benefits, making it a nutritious and refreshing addition to one's diet.

Water kefir's dairy-free composition
Water kefir, also known as tibicos, is a traditional fermented drink that is commonly consumed as an alternative to milk-based probiotic drinks. It is a dairy-free kefir product that is typically made as a probiotic homebrew beverage.
Water kefir is prepared by fermenting a sucrose solution with fresh and dried fruits, using water kefir grains, which are held in a polysaccharide biofilm matrix created by bacteria. The grains culture sugar water or fruit juice, feeding off the sugar to produce lactic acid, alcohol (ethanol), and carbon dioxide gas, which carbonates the drink. Lactobacillus brevis bacteria have been identified as the species responsible for the production of the dextran polysaccharide that forms the "grains".
Water kefir grains can be maintained by alternating between coconut water and sugar water for each batch. This not only provides health benefits but also contributes to reducing waste from packaging, promoting environmental sustainability.
Water kefir can be added to non-dairy milk to make a non-dairy kefir, and extra water kefir grains can be used as a starter culture for fermenting vegetables or as a booster for making gluten-free sourdough starter. Water kefir is a convenient dairy-free alternative to dairy-based fermented beverages, providing a symbiotic mixture of yeast and bacteria, with beneficial yeasts that help the body adapt to stress by aiding in the breakdown of sugars such as lactose.

Water kefir's fermentation process
Water kefir, also known as tibicos, is a traditional fermented drink made with water and water kefir grains. The fermentation process involves adding a starter culture of bacteria and yeast (water kefir grains) to sugar water, which then ferments over several days. The bacteria in the water kefir grains feed on the sugar, producing lactic acid, alcohol (ethanol), and carbon dioxide gas, which carbonates the drink. This process can be done in various sugary liquids such as coconut water, fruit juice, or sugar mixed with water.
The fermentation time for water kefir can vary depending on temperature and the amount of grains used. In general, the warmer the water kefir, the faster it will ferment. It is recommended to ferment water kefir for 24 to 48 hours at room temperature, and it can be left for up to 3 days. If fermented for too long, the bacteria will break down the sugar into acids, making the drink too sour to consume. The ideal temperature for fermentation is between 39°F and 86°F (4°C and 30°C).
During the fermentation process, the water kefir grains grow and reproduce, creating a polysaccharide biofilm matrix. These grains are live bacteria colonies and will continue to reproduce as long as they have food and water. Sea salt can be added to the fermentation jar to give the grains a mineral boost and help them grow. Various types of sugar can be used, including refined white sugar, organic cane juice crystals, raw sugar, brown sugar, and coconut sugar. However, it is recommended to use plain sugar with no additives for best results.
After the first fermentation, the water kefir grains can be strained from the liquid, resulting in plain water kefir. For the second fermentation, the plain water kefir is flavoured by adding fruit juice, fresh or dried fruit, or sugar. This creates a bubbly and effervescent drink. The second fermentation process takes another 24 to 48 hours, and the bottle should be opened slowly as the contents can be explosive.

Water kefir grains
Water kefir is a traditional fermented drink typically made as a probiotic homebrew beverage. It is made by adding water kefir grains to sugary water, where the grains metabolize the sugar during the fermentation process. The final product is very low in sugar and contains beneficial yeasts and bacteria. These probiotics produce vitamins such as B12 and help increase the vitamin and mineral content of the source during fermentation. Water kefir can also be flavoured in various ways.
It is important to note that genuine water kefir can only be made using real kefir grains and not from any packet or powder. Additionally, the weather can sometimes affect the brewing process, and variable temperatures may impact the taste of the water kefir. Overall, water kefir grains offer a unique and healthy way to make a traditional fermented drink with potential health benefits.
