Looking for an easy kombucha tea recipe with step-by-step instructions? This guide shows you exactly how to brew kombucha from your starter, including the precise fermentation timing for a clean, balanced batch. Follow these steps and you’ll get reliably fizzy kombucha at home—without guesswork.
Make kombucha tea by fermenting sweetened tea with a SCOBY until it turns tangy and lightly fizzy—then bottle it briefly to build carbonation. This recipe gives you a repeatable, home-brew workflow: exact ingredients, realistic timing ranges for the first and second ferment, and a clear bottling process so you can dial in flavor consistently.
Ingredients for a Kombucha Tea Recipe
– Sweet tea (black or green) plus sugar to feed the SCOBY
– Use black tea or green tea (avoid flavored teas and anything with added oils).
– Sweeten the tea while it’s still hot enough to dissolve sugar, then cool completely before adding the SCOBY.
– SCOBY and starter liquid to kick-start fermentation
– The SCOBY (the living cellulose layer) drives the culture.
– The starter liquid (from a previous kombucha batch) provides acidity that helps the fermentation start cleanly.
– Optional add-ins for flavor after the first ferment
– Common choices: ginger, berries, citrus slices, vanilla, or a measured juice splash.
– Add flavor during second fermentation so you get aroma + natural carbonation.
> Practical note: Do not add essential oils directly to the ferment. They can inhibit microbial activity and may create unpredictable flavors.
Recommended base recipe (for ~1 gallon / ~3.8 L):
– 1 gallon (about 3.8 L) filtered water
– 6–8 tea bags (or ~2–2.5 tbsp loose-leaf) black or green tea
– 1 cup (200–220 g) sugar total (white cane sugar works best for consistent fermentation)
– 1 SCOBY
– ~2 cups (480 mL) starter liquid
If you brew smaller batches, keep the ratio consistent: ~1 cup sugar per gallon (or ~50–55 g per liter).

Equipment You Need to Brew Kombucha
– Glass jar, breathable cover (cloth or coffee filter), and rubber band
– Kombucha needs oxygen exchange during the first ferment, but you still want to prevent insects and dust.
– A tightly sealed lid is not recommended for the SCOBY stage.
– Bottles for the second ferment and a funnel for easy filling
– Use flip-top bottles or thick glass bottles designed to handle carbonation.
– If you add fruit purée or juice, use a funnel to avoid mess and overflow.
– Measuring tools (thermometer optional) and clean stirring utensils
– A thermometer helps you keep fermentation temperature stable (key for consistent results).
– Use clean, non-metal or food-safe utensils, and sanitize anything that will touch the brew.
Food-safety baseline: Start with clean jars and wash hands before handling the SCOBY. For beginners, consistency beats complexity—buying proper bottles and keeping temperature stable will improve outcomes more than “fancy” equipment.
Step 1: Make Sweet Tea and Add SCOBY
– Brew tea, dissolve sugar, then cool completely before combining
1. Heat water and steep tea until strong (about 10–15 minutes).
2. Remove tea bags (or strain loose tea).
3. Stir in sugar until fully dissolved.
4. Let the sweet tea cool to room temperature (ideally ~20–27°C / 68–80°F) before SCOBY contact.
– Adding SCOBY to hot liquid can stress or kill the culture.
– Add SCOBY and starter liquid to the jar (avoid contamination)
– Pour sweet tea into a clean glass jar.
– Add starter liquid first, then gently place the SCOBY on top (it may float or sink—both are normal).
– Avoid splashing excessively; it can introduce contaminants.
– Cover and place in a warm, stable spot away from direct sunlight
– Cover with cloth or a coffee filter and secure with a rubber band.
– Choose a location with minimal temperature swings—near a vent or sunny windowsill can make fermentation unpredictable.
How to tell you’re on track (first ferment):
– After a few days, you should see tiny bubbles and a slight sour smell (like vinegar meets fruit).
– If you see fuzzy growth that looks like it’s growing above the surface like mold, do not taste it—discard safely and restart.
Step 2: First Fermentation for Flavor and Balance
– Ferment about 7–14 days, tasting gradually for your preferred tartness
– Start tasting around day 7.
– For many home setups, 7–10 days at ~24–27°C yields a classic tangy profile; cooler rooms often take longer.
– Look for the shift from “sweet tea” to “balanced kombucha”:
– Too sweet/flat tasting? Give it more time.
– Very sharp or unpleasantly vinegary? It may be over-fermented.
– Keep the temperature steady to support active fermentation
– Temperature stability is one of the highest-impact controls you have.
– Even a few degrees can alter fermentation speed and final acidity.
– Avoid moving the jar too much during this stage
– Don’t stir aggressively or relocate frequently.
– Movement can disrupt the SCOBY and can introduce oxygen in uneven ways.
Beginner benchmark: If you’re unsure, target a first-ferment taste that’s “pleasantly tart but still drinkable” before bottling. Second fermentation will add subtle extra tang and carbonation.
Step 3: Bottle and Do the Second Fermentation
– Strain or leave as-is, then add flavor if desired
– Many brewers bottle “as-is” for simplicity (keeping sediment is normal).
– If you prefer a clearer drink, strain through a clean mesh sieve.
– Add flavor carefully:
– Fruit juice (1–3 tbsp per bottle depending on bottle size)
– Fresh ginger (thin slices or grated, lightly portioned)
– Berries (muddled or whole, but avoid overloading to prevent excessive sediment)
– Bottle tightly and allow 2–7 days to build carbonation
– Use bottles that can handle pressure.
– Place bottles at room temperature for the second ferment, checking gradually.
– Refrigeration stops fermentation and slows carbonation buildup.
– Refrigerate when it reaches the fizz level you like
– Open a bottle carefully—carbonation can build faster than expected in warmer conditions.
Practical carbonation strategy (especially for fruit add-ins):
– Start with modest flavor amounts, then increase next batch based on how fizzy and tart it becomes.
– Too much sugar/juice in the bottle can lead to over-carbonation and “gushing” when opened.
Troubleshooting Common Kombucha Tea Issues
– If it tastes too sweet, extend first ferment or reduce time slightly next batch
– Sweetness usually indicates under-fermentation.
– Action steps: taste earlier (day 6–7), and add 1–3 days next time. If you overshoot and end up too sour, shorten the next batch.
– If carbonation is low, check bottle sealing and second-ferment time
– Common causes: weak bottle caps, too-cold second ferment, or insufficient ferment activity from the first stage.
– Action steps: ensure bottles are sealed correctly, keep second ferment at room temperature, and confirm you bottled kombucha that was already tangy after the first ferment.
– If mold appears (not fuzzy/normal film), discard and restart safely
– Healthy SCOBY can look like a thin film; it may develop layers and strands.
– Mold is typically fuzzy, spotty, or brightly colored and grows aggressively.
– Action steps: when in doubt, discard. Safety is more important than saving a batch.
Warmly summarize your batch: kombucha tea is all about fermentation time, temperature, and tasting along the way. Brew your next batch using the first and second ferment steps, then adjust flavor and carbonation by tasting and timing—start today and track results for best consistency.
Fermenting sweet tea with a SCOBY is straightforward once you treat the process like a controlled workflow: make balanced sweet tea, cool it fully, ferment until it tastes tangy, then bottle briefly to build fizz. Use stable temperature and regular tasting to “steer” acidity, and flavor in the second ferment to keep control over aroma and carbonation—so your homemade kombucha becomes consistent, not guesswork.
Frequently Asked Questions
How do I make kombucha tea at home step by step?
To make kombucha tea, start by heating water and dissolving sugar, then cool it to room temperature. Add your SCOBY to the sweet tea (along with a little starter liquid) in a clean glass jar, cover with a breathable cloth, and let it ferment 7–14 days. Taste periodically until it reaches your preferred tanginess, then bottle it for a short second fermentation to build fizz. Finally, refrigerate and drink your homemade kombucha tea.
Which kombucha tea recipe is best for beginners?
A beginner-friendly kombucha tea recipe uses simple ratios: typically 1 cup (about 200 g) sugar per gallon of water and 1 SCOBY per batch. Keep fermentation around 70–75°F (21–24°C) to reduce variability and check flavor daily after the first week. Use unflavored tea (black or green) and avoid additional sweeteners that can disrupt fermentation. This straightforward approach helps you learn how to control sweetness, acidity, and carbonation.
Why is my kombucha tea not carbonating, and how can I fix it?
If your kombucha tea isn’t carbonating, it usually means the second fermentation wasn’t long enough, the bottles were opened too often, or the temperature was too cool. Make sure you bottle in sealed glass (not loose caps) and add a small amount of fruit juice, fruit, or sugar as a secondary food source for carbonation. Aim for 1–3 days at room temperature during the second fermentation, then refrigerate to slow fermentation. Also check that your SCOBY is active—if it’s sluggish, carbonation can fail.
What’s the best tea and sugar for a kombucha tea recipe?
For a reliable kombucha tea recipe, choose plain black tea or green tea, because the microbes in the SCOBY depend on tea compounds to ferment properly. Use plain white sugar, cane sugar, or organic sugar—avoid honey, agave, or flavored/“kombucha” syrups since they can be harder to ferment consistently. After brewing the tea with sugar and cooling it, you can add the SCOBY and start fermentation. This keeps your homemade kombucha tea stable and predictable.
How do I know when my kombucha tea is ready to drink?
Your kombucha tea is ready when it tastes tangy, slightly sweet, and less like sugary tea than at the start of fermentation. Most batches finish in 7–14 days depending on temperature and SCOBY activity, so tasting is the best method rather than relying only on time. For a safety check, avoid discarding batches only due to normal “scoby” growth—however, discard if you see fuzzy mold or unusual colors (like pink, orange, or green fuzz). Once it hits your preferred flavor, bottle for carbonation or refrigerate right away.
