How to Make Kombucha at Home

Name: How to Make Kombucha at Home
Yield: 8
Ingredients: 8 cups water; 8 tea bags; 1 cup white sugar; 1 SCOBY; 2 cups starter liquid

Making kombucha starts with a SCOBY (symbiotic culture of bacteria and yeast) and sweet tea. Brew strong black tea with sugar, let it cool, add your SCOBY with starter liquid, then ferment covered with cloth for 7-10 days. The result is a tangy, fizzy drink that gets better with practice.

Total time: 9 days 4 hr
Hands-on: 30 min
Serves: 8
Difficulty: Medium

Ingredients

8 cups water
8 tea bags
1 cup white sugar
1 SCOBY
2 cups starter liquid

Step by step

Brew the sweet tea base. Boil 8 cups of water. Remove from heat and steep 8 tea bags (or 8 teaspoons loose black tea) for 15 minutes. Remove tea bags, stir in 1 cup white sugar until dissolved. Let cool completely to room temperature.
Prepare your fermentation vessel. Use a wide-mouth glass jar that holds at least 1 gallon. Clean it thoroughly with hot soapy water, but avoid antibacterial soap or bleach which can harm your SCOBY.
Add SCOBY and starter liquid. Pour the cooled sweet tea into your jar. Gently place your SCOBY on top with clean hands. Add 2 cups of starter liquid (kombucha from a previous batch or store-bought unflavored kombucha).
Cover and ferment. Cover the jar with a tight-weave cloth or coffee filter. Secure with a rubber band. Place in a warm spot (68-78°F) away from direct sunlight. Let ferment for 7-10 days.
Taste and harvest. After 7 days, taste with a clean spoon inserted under the SCOBY. It should be tangy with a slight fizz. Ferment longer for more tartness, less time for sweeter kombucha.
Bottle and second fermentation. Reserve 2 cups of kombucha and your SCOBY for the next batch. Pour remaining kombucha into glass bottles, leaving 1 inch headspace. Cap tightly and ferment 1-3 days at room temperature for carbonation.

Tips & troubleshooting

Your SCOBY will grow a new layer on top each batch. This is normal. You can separate layers and share with friends.
If you see fuzzy mold (usually green or black) on top, discard everything and start over. Healthy SCOBY looks like a rubbery pancake.
The warmer your fermentation spot, the faster it ferments. Cooler temperatures slow it down but often create better flavor.
Always keep metal away from your kombucha during fermentation. Use glass, plastic, or wood for stirring and storing.
Save some plain kombucha between batches. This starter liquid is crucial for maintaining the right acidity.
Your first few batches might taste different as your SCOBY adapts to your environment. Be patient.

Variations

Green Tea Kombucha. Replace half the black tea with green tea for a lighter, more delicate flavor. Use the same sugar ratio and fermentation time.
Flavored Second Fermentation. Add fruit, herbs, or spices during bottling. Try ginger and lemon, berries, or fresh mint. Strain before drinking.
Continuous Brew Method. Use a large vessel with a spigot. Harvest kombucha from the bottom while leaving the top portion to keep fermenting. Add fresh sweet tea to replace what you've taken.

Questions

Where do I get a SCOBY to start?: Get one from a friend who brews kombucha, buy online from reputable suppliers, or grow your own by leaving store-bought kombucha (with live cultures) covered with cloth for 2-3 weeks until a film forms.
What if my kombucha isn't fizzy enough?: Fizziness comes mainly from the second fermentation in sealed bottles. Make sure your bottles seal tightly and ferment 1-3 days at room temperature. Warmer temperatures and a bit of added sugar can increase carbonation.
Can I use different types of sugar?: White sugar works best because it feeds the SCOBY most efficiently. You can experiment with small amounts of honey, maple syrup, or coconut sugar, but these can change fermentation and may weaken your SCOBY over time.
How long can I store finished kombucha?: Refrigerate finished kombucha to slow fermentation. It keeps for several months in the fridge, though flavor will continue developing slowly. It won't go bad, but may become more vinegary.
What do I do with my SCOBY when I travel?: Store your SCOBY in fresh sweet tea in the refrigerator for up to a month. For longer periods, dehydrate it on parchment paper or freeze it in starter liquid. Reactivate slowly with fresh batches when you return.
