Can I use GT'S to start a SCOBY?
Was about to start growing a SCOBY and read this ... Any one know if it's true and shouldnt wast my time starting one with a store bout bottle of Kombucha?

Why can’t I grow a kombucha scoby from a store-bought bottle anymore?

You may or may not remember the great kombucha recall of 2010. Kombucha was pulled off store shelves across the U.S. because it had been feared that some brands were too alcoholic to be sold as a regular beverage.

Most major brands reformulated their kombucha, then put it back on store shelves promising that it would no longer be possible for their kombucha to contain too much alcohol.

Whatever they did, I think they made it virtually impossible to grow a kombucha scoby from a store-bought bottle of kombucha anymore.

Some companies, like Dave’s GT, have even started adding a supplement called GBI-30 to their “Enlightened” (AKA kombucha for those under 21) bottled booch. GBI-30 is a patented pro-biotic that is non-native to the Kombucha culture.

I don’t know precisely why they added this to their formula, or how it prevents the growth of alcohol, but it doesn’t make sense to include GBI-30 in your homemade kombucha scoby. It’s not part of the normal fermentation process for kombucha, so I can imagine that it is also somehow interfering with our ability to grow a fresh kombucha scoby from the bottled brew

I believe (but can't say for certain) that their "Classic" line is un-pasteurized and thus may contain more than 0.5% ABV. In some states it's sold only to adults over 21 yrs old. This one seems to be unflavored: http://synergydrinks.com/index.php/products#classic-kombucha/classic-kombucha-original.

If you use that, I'd add maybe 2oz of sugar to the 16oz bottle and give it at least 4 weeks to develop a scoby. Don't drink the resulting mix because it'll probably be very vinegary. Instead save about a cup to start a "hotel" for future baby-scobys, and use add the remaining cup (and scoby of course) as starter for your first real gallon batch of sweet tea.

The Enlightened series is the pasteurized one that has the maybe/sorta/hopefully patented probiotics. I'm guessing that one won't produce a scoby. That's here: http://synergydrinks.com/index.php/products#enlightened-kombucha/enlightened-kombucha-organic-raw-kombucha-original

About 8 months ago I grew up a SCOBY from a Raw GT's Original Flavor bottle and it's been going strong ever since.

Enlightened. It took me some time to get it going. The first mother was very thin, so I added extra dregs from another bottle every cycle. In the end it took me three bottles, but at this point my SCOBY is almost two inches thick from batch to batch.

I just started this process myself. Here's hoping.

use 3-4 bottles and plenty of volume for your first batch. First scoby is pretty thin but give it time and you'll have zoogleal mats growing out of your ears. we split ours into 3 1-gallon batches over time and the scobys were 2-3inches thick each, finally gave a few away and set the others free to roam in nature. Too much kombu, too much scoby to know what to do with. Also, homemade kombucha is a far cry from stuff you buy commercially, and can have potent effects if let to sit too long.

Here is the TTB's take on kombucha here in US, http://www.ttb.gov/faqs/kombucha-faqs.shtml

Two weeks ago, I did an experiment with a four day old half bottle of GT's Guava Goddess. Poured it into a mason jar that had sweetened tea in it. Freshly brewed with pure cane sugar. Now, here's the SCOBY! (Picture is a few days old and it's even larger now.)
