Step 1: Materials
2. A clean glass jar, preferably rinsed out with boiling water prior to use. Preferably a small one with a rather narrow throat.
3. Tea. Black or green, as long as it's got no additives. I used some kind of green tea in a tin with no English writing, and it worked just fine. My last culture I did with black tea, worked just fine.
5. Cheesecloth or similar cloth. I use sterile gauze I pilfered from a first aid kit and it works just fine.
