Brewing Starter Tea is an essential element if creating our Premium Craft Kombucha Recipe. This young & lively Starter Tea brings in a fresh yeast profile to your finished product which can be really fantastic.

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 is very high in yeast, bacteria & alcohol. This combination is great for tasty home brews but not ideal for commercial kombucha at scale. This is why we use Starter Tea in combination with Manna-K.


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:Sourcing your first SCOBY & Starter

If you order 1 Litre it takes about 2 weeks to be able to make 10x the amount. So you’d get it, add tea, sugar & water and ferment for 2 weeks to get 10L, then take that 10L and do another 2 weeks to get 100L, then you will be ready to make your first 1000L.

2:Infusing the Tea

Step1: Add10Kg of Tea to the mixing tank ,then add 150L 85℃ Hot Water .

Step2: Recirculate Hot Tea Liquid with pump for 30-45 min.

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.
