Making Kombucha at Home

Kombucha has become a popular drink for those seeking a tasty, probiotic-rich beverage. Buying kombucha from stores can get expensive, and the flavours are often limited. Making kombucha at home offers a way to enjoy this fizzy, tangy drink while saving money and customizing flavours.

When we were commercially brewing kombucha we learned that most products available on the grocery store shelves have been processed in ways that will increase their shelf life but reduce the viability of active cultures. Kombucha needs to be tested for alcohol levels at production and expiry to make sure that its below a certain threshold. Common processes manufacturers will do are microfiltering and pasteurization to ensure the cultures are less able to ferment and produce more alcohol ensuring a long shelf life at the store.

This guide explains why making kombucha at home is a smart choice and provides easy recipes to get started. This recipe is lower in sugar than others found online. We found while brewing commercially that the residual sugar in classic recipes was too high unless left to ferment completely creating a product that was too much like vinegar. The method will create a kombucha that's light, easy drinking, slightly sweet, tart and refreshing.

Why Making Kombucha at Home Is Healthy and Cost-Effective

Health Benefits of Kombucha

Kombucha is a fermented tea that contains probiotics, which are beneficial bacteria that support gut health and a healthy gut is the foundation of our health.

When you make kombucha at home, you control the sugar content and avoid preservatives or artificial flavors often found in store-bought versions. This means you get a cleaner, more natural drink that fits your dietary needs. You can also preserve more of the active cultures with home brewed methods.

Saving Money by Brewing Your Own

Store-bought kombucha can cost between $4 and $6 per bottle. If you drink it regularly, this adds up quickly. Brewing kombucha at home costs just a few cents per serving once you have the basic supplies.

A starter kit with a SCOBY (symbiotic culture of bacteria and yeast), tea, and sugar can produce gallons of kombucha over time. This makes homebrewing a budget-friendly option for anyone who enjoys this drink daily or weekly.

What You Need to Start Brewing Kombucha

Before diving into recipes, gather these essentials:

• SCOBY: The living culture that ferments the tea.

• Sweetened tea: Black tea with sugar feeds the SCOBY.

• Glass jar: A 3-gallon jar works well.

• Breathable cover: A cloth or coffee filter secured with a rubber band.

• Bottles for storing: Glass bottles with tight lids for carbonation.

  
  

You can find SCOBYs online, from kombucha brewers, or even grow your own from store-bought kombucha (as long as it is truly live and hasn't been pasteurized)

Basic Kombucha Brewing Recipe

This simple recipe produces about 2 gallons of kombucha in 7 to 10 days.

Ingredients

• 1 SCOBY with starter liquid

• 8 bags of black tea (or 2 tablespoons loose leaf)

• 1 cup white sugar

• 2 gallons of filtered water

  
  

Instructions

1. Make the sweet tea: Boil water and steep tea bags for 10 minutes. Remove tea bags and stir in sugar until dissolved. Let cool to room temperature.

2. Combine tea and SCOBY: Pour the cooled tea into the glass jar. Add the SCOBY and 500mL of starter liquid.

3. Cover and ferment: Cover the jar with a breathable cloth and secure it. Place the jar in a warm, dark spot (around 70-75°F).

4. Wait and taste: After 7 days, start tasting the kombucha daily. When it reaches your preferred balance of sweetness and tartness, it’s ready.

5. Bottle and refrigerate: Remove the SCOBY and about 2 cups of kombucha to start your next batch. Bottle the rest and refrigerate.

   
   

Flavouring Your Kombucha

Once you master the basic brew, you can add flavours during a second fermentation. This step adds natural carbonation and delicious tastes. Adding juice or concentrated tea high in antioxidants like elderberry or hibiscus will add more antioxidant power to your final brew.

Popular Flavour Ideas

• Fruit juices like apple or pomegranate

• Freshly juiced ginger

• Concentrated Herbal tea like Hibiscus or Elderberry

  
  

How to Flavour

1. Pour kombucha into bottles, leaving about an inch of space.

2. Add your chosen flavourings.

3. Seal bottles tightly and leave at room temperature for 2 days to carbonate.

4. Refrigerate to stop fermentation and enjoy chilled.

Tips for Safe and Successful Brewing

• Always use clean, non-metal utensils and containers.

• Avoid flavored teas with oils or additives during the first fermentation.

• Keep the brewing jar away from direct sunlight.

• If mold appears (fuzzy, black, or green spots), discard the batch and start fresh.

• Store your SCOBY in some kombucha liquid between batches.
