Ingredients
The ingredients used in making Jun and kombucha are one of the primary differences between the two. While kombucha generally utilizes black tea and refined sugar as its fermentation medium, Jun is cultured with green tea and raw honey.
Taste
The taste of the two fermented beverages reflects that disparity in ingredients. While very mature kombucha can have a strong vinegar note to it, Jun tends to be a bit less acidic. Jun is generally lighter and fizzier in flavor, due both to its ingredients and its microorganisms.
