3. Add the sweet tea, SCOBY, and starter liquid to a large glass or porcelain jar. I use a large iced tea jar that has a spigot at the bottom; the spigot is made of metal, which can be affected by the acidic drink, so I clean it thoroughly every few months. If buying a jar with a spigot, look for one with a plastic spigot (but it’s not a deal breaker). Something like a large glass cookie jar will work as well.
