FAQ

Kombucha is a naturally fermented tea, made from tea, sugar, and a live culture called a SCOBY (Symbiotic Culture Of Bacteria and Yeast). Originating in China centuries ago and later popularized in Japan and worldwide, kombucha is a probiotic beverage rich in:

  • Live cultures (friendly bacteria and yeasts)
  • Antioxidants
  • Natural organic acids

A SCOBY is a living culture that ferments the tea and sugar into kombucha. It creates all the natural probiotics, antioxidants, and acids that make kombucha a healthy, raw probiotic drink.

Myth busting: The SCOBY is not a mushroom :  it’s a symbiotic culture of bacteria and yeast.

Want to make your own kombucha at home? If you’d like a SCOBY, write to us and we’ll provide one!

Kombucha can be enjoyed anytime:

  • Morning or during the day for a natural energy boost
  • Before or after meals to support digestion

Absolutely! Sediment is just natural yeast and bacteria that settle at the bottom. It’s harmless and indicates your kombucha is alive, raw, and unpasteurized.

Keeping kombucha raw and unpasteurized preserves all the live probiotics. Pasteurization would kill the good bacteria, reducing the health benefits. Our small-batch kombucha is crafted to keep it alive, healthy, and full of flavor.

Like all traditional kombucha, ours may contain traces of natural alcohol (up to 1%), similar to a ripe fruit. This is completely normal for a living, raw, fermented tea.

Because it’s alive! Each bottle ferments naturally, without pasteurization or artificial flavors. Small variations in taste, aroma, or fizz are a sign of real, living kombucha.

Yes! Refrigeration:

  • Keeps kombucha fresh and flavorful
  • Preserves live probiotics and cultures
  • Prevents extra fermentation in the bottle
