Sage is one of my favorite herbs. Fresh sage is more flavorful than dried sage, and the sage plant is beautiful with pretty red flowers. You can use the leaves to make tea, which has been called the "thinker's tea," and it even helps ease depression. So I place the leaves in kombucha to produce a similar benefit.
Add 3 ounces of the strawberry juice to a 16-ounce bottle. Add sage leaves.
Fill with Basic Kombucha and place in a thick glass bottle made for brewing, leaving a little headspace at the top of the bottle.
Let sit at room temperature for 5-14 days checking for fizziness every couple of days. Warmer houses above 70 degrees will finish faster. (Fresh juice will be done closer to 5 days.)
Once finished, drink right away or store in the refrigerator.
