Oolong Tea

Partially oxidised between green and black — aromatic, rounded and adaptable.

Oolong sits between green and black in oxidation, so it brings a rounded, aromatic character that ferments well. Lighter oolongs behave more like green tea, darker ones more like black. It is a good choice for someone who wants their plain kombucha to taste interesting without adding fruit later.

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

Oolong is a true tea and contains caffeine; fermented kombucha also contains a small percentage of alcohol. This is normal and expected, but it means kombucha is not caffeine-free and not alcohol-free. Speak to a healthcare professional before drinking kombucha if you are pregnant, breastfeeding, giving it to a child, or advised to avoid caffeine or alcohol.

Practical guidance

  • Try the same oolong brewed two ways — light and strong — to see how much steeping strength carries through.
  • Roasted oolongs tend to ferment slightly slower; keep the temperature steady.
  • Oolong blends well with a small proportion of black tea for a sturdier pellicle.
  • Note the roast level in your brew log; it is the variable that changes the most between oolongs.

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.
