Heat about 3.5 quarts (14 cups) of water in a large pot until it boils. Remove pot from heat.
Add tea bags and allow to brew for about 5-10 minutes, depending on how strong you like your tea.
Remove tea bags and stir in 1 cup of sugar until it dissolves.
Let sweetened tea sit until it reaches room temperature.
Once cooled, pour sweetened tea into the 1-gallon glass container.
Add the starter tea.
Add the SCOBY.
Cover container with a coffee filter and secure with a rubber band.
Place container in a dark and slightly warm area.
Wait one week. You should see a new SCOBY beginning to form. That’s good! Use a straw to taste test your kombucha. If it’s not to your liking, wait a few more days and taste again. Once you like the taste, it’s done and ready to bottle or add flavorings!
