Question

‘Kombucha tea’, ie fermented tea, is widely accepted as “permissible”, according to the people I had asked. However, I came across a brand in which the ingredients listed included not only black and green tea, but also several fruit juices. One of the fruits listed was ‘organic white grape juice’.

Q: will the presence of grape juice in kombucha tea affect the permissibility of this beverage?

Answer

In the name of Allah, The Most Gracious, The Most Merciful

Waʿalaykum al-Salām wa raḥmat Allāh wa Barakātuh. 

You may consume regular kombucha so long as the grape juice does not ferment.[i]

And Allah knows best.
