Bring water to a boil over high heat, then turn off the heat.

Stir in sugar. (One cup of sugar for every one gallon of water.)

Add your black tea (half a cup -or eight tea bags- per gallon of water), let steep for 5-10 minutes.

Strain and compost the tea.

Let the tea cool til warm or room temperature.

Pour the tea into your jar, and add in the scoby.

Cover your jar with either a washcloth or coffee filter, secure with rubber band.

Put your brew somewhere out of direct sunlight. Let the kombucha sit for between 5-10 days, tasting regularly, until done.
