Green Tea

Less oxidised, lighter and greener — a gentler base with a fresher finished flavour.

Green tea is minimally oxidised, so it gives a lighter, grassier kombucha with less maltiness than black tea. It contains similar compounds but a different balance, and some brewers find the culture adapts more slowly to a 100 percent green tea base. A common approach is to blend green with black at a ratio of about a third green to two thirds black.

Applicable brewing stages

  • First Fermentation
  • Second Fermentation
  • Flavoring
  • Bottling
  • Cleaning & Testing

A highlighted stage means this tool has a direct role at that point in the process. Ticking several stages is normal — a thermometer, for example, is useful during both the first and second fermentation.

Safety notes

Green tea contains caffeine, and kombucha made with it contains a small amount of alcohol from fermentation. Neither figure is zero. Anyone advised to limit caffeine or alcohol intake should consult a healthcare professional before drinking kombucha. Kombucha is not a rehydration drink and should not replace water.

Practical guidance

  • Brew green tea at a lower temperature than black; boiling water makes it harsh.
  • Give the culture two or three batches to adjust if you switch from black to green.
  • A green-dominant brew tends to taste ready slightly earlier, so start testing pH sooner.
  • Avoid matcha — the powder stays suspended and makes the brew cloudy and chewy.

Please read before you brew

This page is educational reference material, not professional brewing, food-safety or medical advice. Equipment handling, hygiene practice and local rules vary, and nothing here guarantees a particular brewing result.

  • Home brewing rules differ by country, state, province and municipality, and they change over time. Check your own local requirements — including any permit, licence, volume limit or minimum age — before you brew, bottle or share what you make.
  • Use food-grade equipment only. Vessels, bottles, tubing and utensils that were not made for food or drink may release unwanted compounds or shelter microbes.
  • Work in a well-ventilated space, keep hot liquids away from children and pets, and follow the manufacturer's instructions for every appliance you use.
  • Bottles under pressure can fail. Use bottles designed for carbonated drinks, do not over-prime, and refrigerate once the carbonation is right.
  • For anything involving gas pressure, electricity, high heat, chemical cleaners or acids, consult a qualified professional.

Finished kombucha contains trace alcohol and caffeine. It is not suitable for children, and anyone who is pregnant, breastfeeding, immunocompromised, diabetic or taking medication should speak to a healthcare professional before drinking it. Kombucha is a food, not a medicine, and it does not treat, cure or prevent any disease.
