Equipment & Packaging
Method
Make Sweet Tea (Base)
- 1
Boil and dissolve sugar
Bring 14 cups (3.3 liters) of water to a boil in a large pot. Remove from heat, add 1 cup granulated sugar and stir until fully dissolved.
- 2
Steep tea
Add 6 black tea bags and 2 green tea bags to the hot sugar water. Cover and steep for 10–15 minutes to extract flavor without excessive bitterness.
- 3
Cool the tea
Remove tea bags (press gently against the side with a spoon and discard). Let the sweet tea cool to room temperature (about 1–2 hours). Reserve 1 cup of the cooled sweet tea in a clean container to mix with starter if needed.
Primary Fermentation
- 4
- 5
Cover and ferment
Cover the jar with a breathable cloth or coffee filter secured with a rubber band. Place the jar in a warm (68–78°F / 20–26°C), dark spot with good airflow. Ferment for 7–10 days, checking for taste starting at day 7. Primary fermentation yields a mildly tangy kombucha.
- 6
Check SCOBY and taste
After about 7 days, begin tasting daily: insert a clean straw beneath the SCOBY and draw out a small sample. When the sweetness has reduced to a pleasant balance of sweet and tart, the kombucha is ready for bottling (usually 7–14 days depending on temperature and starter strength).
Prepare Flavorings for Secondary Fermentation
- 7
Choose flavor profile
Select one rotating flavor or combine small amounts of two. Typical combinations: ginger + lemon; mixed berries + mint; pineapple + lavender. Measure flavoring ingredients listed under Flavoring.
- 8
Prep fruit/herbs
For fresh ginger: peel and finely grate 2 tbs. For lemon: juice to yield ~1 cup and strain seeds. For berries or pineapple: lightly mash or blend 1–2 cups to release juices. For mint or lavender: bruise leaves/buds to release aroma.

Bottling and Secondary Fermentation (Carbonation & Flavoring)
- 10
- 11
Fill bottles
Strain the fermented kombucha through a fine mesh strainer into a pitcher to remove any large particles and loose yeast. Leave the SCOBY and about 1/2 cup of kombucha in the fermentation jar as starter for the next batch. Fill each bottle, leaving about 1 inch (2.5 cm) headspace.
- 12
Seal and condition
Seal the bottles tightly. Leave at room temperature (68–75°F / 20–24°C) away from direct sunlight to carbonate for 2–5 days. Check carbonation daily by gently opening a bottle to relieve pressure and assess fizziness. When desired carbonation is reached, move bottles to the refrigerator to slow fermentation.

Maintenance & Next Batch
- 14
Save SCOBY and starter
Keep the SCOBY and at least 1–2 cups of the kombucha liquid in the jar to start your next batch. Add fresh sweet tea (cooled) and repeat the process. Periodically refresh the SCOBY by discarding any discolored or moldy layers (mold appears fuzzy and should be discarded).
- 15
Rotate flavors
Rotate the flavor additions each batch to create the 'Rotating Flavors' concept: try seasonal fruits (peach, apple), herbs (basil, thyme), or floral notes (rose, hibiscus) using the same secondary fermentation method—adjust quantities to taste.
