Our Dehydrated Kombucha Starter is the perfect way to experience Kombucha fermentation at home. 

The live cultures are shipped in a dehydrated state, so it can stay on your shelf until you are ready to get started!

After rehydrating the SCOBY, simply add the kombucha starter to sweet tea and ferment away to make a healthy, soda-like kombucha with all the tart zing you want.

Making Kombucha at home is not only a great way to save money, but it also allows you to control the ingredients and make a healthier tea! 


  • Whole mustard seeds
  • Kombucha
  • Sea salt (optional)
  • Herbs and spices to taste:
    • Garlic cloves can be added during the brewing process or the blending stage
    • Add Honey or maple syrup during the blending stage
    • Chiles can be added during the brewing process or the blending stage
    • Turmeric adds a yellow color if desired; add during the blending stage
    • Add other herbs during the brewing stage


  1. Fill a glass container or ceramic crock about half full of mustard seeds. Add sea salt to taste (about 1/4 tsp. per quart).
  2. Add well-fermented kombucha tea to about 1/2-inch liquid above the seeds.
  3. Cover the container loosely with a loose lid, towel, or paper coffee filter. Check the mustard seeds periodically and add more Kombucha as necessary to keep them covered and moist. As the seeds absorb the kombucha they will swell, and it is important to keep them sufficiently moist. After a week or two the seeds will be soft and will pop when you bite them. At this point the seeds are ready for the blending stage but can continue to sit and ferment for up to a month, if desired provided, they are kept moist.
  4. One the seeds are sufficiently soft, use a food processor or blender to blend the mixture to the desired consistency. More kombucha can be added to give the mustard a thinner consistency. Vinegar can also be added to increase the level of tang.
