Good bubbles. Clear answers.

First fermentation usually takes 7–14 days at room temperature. Taste around day seven; warmer rooms move faster and cooler rooms move slower.

A symbiotic culture of bacteria and yeast. It is the rubbery disc that helps turn sweet tea into tangy kombucha.

It can be when you use clean equipment and a healthy culture. Discard any batch with fuzzy colored mold or a rotten smell.

Home-brewed kombucha can contain trace alcohol, often around 0.5% to 1.5%, and the amount varies with time and conditions.

Yes. Add fruit, juice, or herbs during a short second fermentation in pressure-safe bottles, then refrigerate.

It should bubble reliably within a day of feeding and smell pleasantly yeasty and lightly sour—usually after 3–7 days.

A yeasty, slightly sour smell is normal. A rotten or putrid smell means you should discard it, clean the jar, and start again.

It can last indefinitely with regular feeding. Refrigerated starters can often go a week or two unfed, then need a couple of feeds before use.

Usually only a small amount, but it is not reliably zero. Fermentation time, sugar, and temperature all affect the result.

Kombucha uses tea and a SCOBY over one to two weeks. A ginger bug is a wild starter used to carbonate sweetened drinks over a few days.

No. Clean glass jars, breathable covers, rubber bands, and pressure-safe bottles cover the basics. A pH strip is optional.
