Producing a high-quality batch of our Premium Craft Kombucha Recipe requires the use of Brewing Starter Tea as a key ingredient. This young and dynamic Starter Tea introduces a vibrant yeast profile to your finished product, which can add a wonderful depth of flavor.

Recipe for 1000 Litres of Starter Tea


  • 10 kg of Sencha Green Tea (goal: 10 g/L)
  • 250 Litres of Hot Water forInfusion
  • 60 kg of Organic Sugar (goal: 6 – 6.5 Brix or 60g/L)
  • Water added in at the end, to reach a total volume of 900L
  • 100 Litres of Starter Tea Liquid (goal: 10% of the totalvolume)
  • Optionally 1% SCOBY


Starter culture contains high levels of yeast, bacteria, and alcohol, which can be beneficial for producing delicious home-brewed kombucha. However, when it comes to commercial kombucha production at scale, this combination can present certain challenges. This is precisely why we employ a combination of Starter Tea and Manna-K in our commercial operations.


  1. Do not overfill the tea bag, give the leaves some space for a better infusion. Consider the leaves will expand by 10 times their dry volume.
  2. Use bag-cut tea leaves for an efficient infusion.
  3. We use a standard kombucha starter with 2.85 – 3.15 pH.
  4. Use a recipe sheet to keep track of what you are doing, and to track changes. Most importantly, log your pH and Brix values to compare and improve your recipes as they evolve.

1. Obtaining your first scoby and starter

If you order 1 liter of starter, it typically takes around 2 weeks to produce enough kombucha for 10 times that amount. To get started, you would add tea, sugar, and water to the starter and ferment the mixture for 2 weeks to obtain 10 liters of kombucha. From there, you can repeat the process for another 2 weeks to obtain 100 liters, and then you’ll be ready to make your first 1000 liters.

2. Infusing the tea

Step 1: Add 10 kilograms of tea to the mixing tank, followed by 150 liters of 85℃ hot water.

Step 2: Recirculate the hot tea liquid with a pump for 30-45 minutes.

3. Mixing sugar into your hot tea infusion

Step1: Pump Hot Tea Infusion to Mixing Tank while passing through a Strainer + Basket Filter 100 Mesh/149 Micron.

Step2: Add in the Sugar and mix for 10 mins until all solids are dissolved.


  1. Sanitize all equipment before use.
  2. A 100-mesh filter (149 microns) is OK for the bag-cut tea.
  3. The more you stir your tea during the infusion the more you facilitate the extraction of the good things from it. Make sure you have a powerful and well-set pump. If you don’t have one, and feel that your brew needs a little help, you can use a brew spoon to stir it and create that agitation in the tank.

4. Adding starter & scoby to the tea infusion

Step1: Add Cold Water to the Tea Infusion until it is up to 900L.

Step2: When the liquid is less 28 Degrees Celsius you can add in the Starter Liquid & SCOBY.


  1. You have to make sure your sweet tea is under 28°C before adding starter or you can kill the starter culture.
  2. Keep the mixer going throughout the whole process.

5. Transfer inoculated sweet tea to your fermenter
