I just received this question in my inbox
"Hi Hannah:
I have my first batch ever brewing and can't wait.
I'd like to run this by you.....do you have any opinions about continuous brewing systems vs. traditional method. Any thoughts, pros and cons?"
Let's first figure out what each method is and then look at the differences between them
Traditional Brew

The traditional brewing method of Kombucha consists of fermenting your culture for 7-14 days, depending on taste preference, then moving the Kombucha to glass containers where other flavors may be added. These are then permitted a secondary fermentation process where the sugar in the fruit or ginger reactivates the yeast cultures, but in an anaerobic environment (read as - the lid is on and there is no oxygen). This creates more fizz and pleasant flavors. Once the optimum flavor is reached (usually 2-4 days later) then the brew is refrigerated to stabilize fermentation. The cold of the refrigerator decreases the fermentation activity.
Now you have a delicious health beverage that also contains the anti-oxidants and other healing properties of the flavors you have combined with it.
Then you start the process all over again with a fresh batch of nutrient solution (tea & sugar) with a cup of the starter liquid and SCOBY. You wait another 2 weeks for a new batch to come to fruition. Provided you have enough jars of Kombucha brewing to get you through the 2 weeks while waiting for the next batch, you will always have Kombucha on hand.
PROS
*flexibility to enjoy flavors
*ability to experiment with different brewing methods and ingredients
*bottles on hand to bring to parties or share with friends or take to work
Continuous Brew

Continuous brew differs in that instead of waiting 2 weeks for each brewing cycle to come to fruition, you are consistently drawing Kombucha from your batch and then replacing it with nutrient solution every couple of days.
The flavors might be added to each individual cup of tea, but not to the entire batch.
The benefit to continuous brew is that you don't have to wait 2 weeks for the batch to come to fruition as it is using a much larger portion of fermented tea as the starter. Also, research by Michael Rossin has shown that certain acids aren't expressed in the fermentation process until 21-30 days in. For most people brewing in gallon size containers, that would mean the taste would be vinegar - which is not a pleasant taste.
PROS
*always Kombucha on hand
*other healthy acids are expressed later in the fermentation process
WHAT DO I DO?
I like the process of decanting the Kombucha and making flavors - however, I do have a continuous brew going at the same time. I use it to top off the last 10-20% with continuous brew - that way I'm infusing the healthy acids into my bottles of Kombucha, but I also get the yummy flavors. I also will use a bit of the continuous brew as starter for my next batch.
