A: In the first 7 days of brewing, your culture is processing the tea and sugar and beginning to grow the new culture on top. If you move it, it disrupts the process and makes it hard to grow the new culture. Once the new culture has formed, you can gently move the jar should you wish. Don't panic if you moved it around during the first 24 hours, it's fine. Just try not to bump or move it during days 2-7.
