I'm a big fan of the store-bought kind but it's rather expensive so I'm considering making my own.    I read some how-to articles on it so generally I understand the process, but I wanted to see if anyone else has tried it and has any specific advice...    Some questions I have:    - where do I buy the SCOBY? It it something I can buy at Whole Foods?    - what is the best way to clean the containers that will be used for brewing and storing to be sure that nothing bad grows?    - my home will probably be the right temperature to brew it without any other climate control in the early fall, summer, and late spring, but the other half of the year the temp hovers around 65-68F. Apparently that isn't a good temperature and will allow bad microbes to grow. What are some good options to keep the kombucha at the right temperature without heating my ENTIRE home?    - are there any tea varieties that translate well into kombucha? Likewise, any teas that especially DON'T translate well?    - where is the best place to get recipes that are dupes of G.T's or Synergy flavors?    - any other advice or recommendation is welcome as well!
