Kombucha Brewing Ratio: A Reliable Ingredient Scale Guide? ›

When brewing kombucha, the most important rule of thumb is the sweet tea to starter tea ratio. The sweet tea to kombucha starter tea ratio is 9:1 or 90% sweet tea to 10% kombucha starter tea.

Recipe Notes

Batch Size: To increase or decrease the amount of kombucha you make, maintain the basic ratio of 1 cup of sugar, 8 bags of tea, and 2 cups starter tea per gallon batch. One scoby will ferment any size batch, though larger batches may take longer.

If you feed it too much, the culture will be too dilute and the scoby will take longer to form. If you don't feed it at all, cellulose production will also be slow due to lack of nutrients. Our recipe feeds the culture at a ratio of 2:1. 5.

For each gallon of sweet tea, use 1 large SCOBY (5-6 inches across, ½ – 1 inch thick) and 1-2 cups strong starter liquid.

The equation for understanding fermentation is C6H12O6 (glucose) → 2 C2H5OH (ethanol) + 2 CO2 (carbon dioxide). And lastly, the alcohol is converted into acetic acid by the bacteria.

When brewing kombucha, the most important rule of thumb is the sweet tea to starter tea ratio. The sweet tea to kombucha starter tea ratio is 9:1 or 90% sweet tea to 10% kombucha starter tea.

The Centers for Disease Control recommends that four ounces of kombucha can be safely consumed one to three times a day. Overconsumption can lead to headache, nausea, gastrointestinal distress, or ketoacidosis.

This is fine if they're getting too large or if you'd like to split them up to move some to a SCOBY hotel/share with a friend. You can't hurt your SCOBY by ripping it or cutting it. Its shape doesn't matter since new ones will always take the shape of the surface of whatever container you place it in.

A scoby can usually survive without being fed or oxygenated for: 6 months in the fridge. 3 weeks at room temperature.

If your scoby gets more than one inch thick in a typical one-gallon brew, it's time to consider separation.

With proper care, SCOBYs can last many generations. But when you see excessive, dark yeast growth on a SCOBY layer, or if it starts producing Kombucha that tastes bad or overly acidic, it's time to get a new one. New kombucha recipes can be made.

The direct answer is that you never need to replace your SCOBY if well taken care of, but when it comes to the pellicles (or “mothers” as they are so lovingly referred to), those can be thinned out with each brew.

The scoby will then go dormant and can be kept for up to 6 months. However, we've already seen scobys that had been forgotten for over a year in a corner of the fridge come back to life without any problem. These little creatures are resilient!

Kombucha is a fermented, fizzy, slightly sweet form of black tea. Some praise the drink for having several possible health benefits, such as constipation relief and prevention. While it is unlikely to substitute medical laxatives, kombucha may help the frequency and consistency of stools.

A SCOBY can be stored for up to 6 weeks when in a container with sweet tea, using the sugar and nutrients in the tea as food to stay alive. After 6 weeks, the now sugar-less and vinegary kombucha will need to be replaced with a new batch of sweet tea to keep the SCOBY well fed.

Yes, spring water is considered the best option for brewing kombucha because it naturally contains the minerals necessary for a healthy kombucha culture.

Use 4 bags if you're using 2 quarts of water; 8 bags if you're using a gallon of water. The sun tea method also works with larger tea bags that are meant to make iced tea. Simply use the recommended amount of water per large tea bag that's on the box's directions.

A gallon is equivalent to 128 fluid ounces, and typically, it's recommended to use one tea bag for every 8 ounces of water. Based on this ratio, you would use: 16 tea bags for a gallon to achieve a standard strength.

Black tea is considered best as it contains the nutrients that the scoby likes. It can produce quite a full, fruity flavour but many people prefer to do a mix of teas such as half black and half green or white tea. Either teabags or loose tea can be used. Tea that has added oils such as Earl Grey should be avoided.

To reap the benefits of kombucha without consuming too many calories, limit your intake to one to two 8-ounce (240-ml) servings per day. It's important to note that most kombucha bottles contain two servings — 16 ounces or about 480 ml.
