Yes please..
Get a SCOBY ( culture by ordering online)
Take a litre water and put it to boil. Add 4 tbsp sugar( approx 60-70g) & add 2 tbsp regular tea into it. Leave it for some time to bring it to room temp.
Then get a glass jar and fill it with the freshly prepared tea and add SCOBY. Cover the jar with a coffee filter/ cotton cloth & seal it with a rubber band. Leave it for 6-7 days in a dark place.
After 7 days,keep aside 200 ml kombucha tea with SCOBY for the next batch.
I hope this information is helpful
