Kombucha getting started.
Following up on the two little side fermentation projects that I have going on: kombucha and a mixed fruit cider/wine thing….
First, on the kombucha, I have reached out to some folks online regarding my progress, because I don’t really know how this is supposed to look. I’m using 1 gallon of green tea, a cup of sugar, and the dregs from a bottle of kombucha soda. After a couple of days, I have some bubbles around the perimeter of the carboy, a small “island” in the middle, and a few floaters that appear to be dark green and hang down like a “beard”.
perimeter bubbles and “beard” floater.
There’s a little more sediment at the bottom than I started with, too. The little floaters are my biggest concern…all the pictures that I’ve seen online show the “SCOBY” (Symbiotic Colony of Bacteria and Yeast) are off-white to tan in color. A little further research shows the floaters to be common…need to watch out for mold growing on top. That would be mean throwing out the batch. Also, it sounds like I may need to make a “baby” SCOBY and start another batch to grow a “mother” SCOBY? It’s a learning experience, that’s for sure!
Moving on to my mixed fruit little experiment: I racked the juice and it was still pretty thick on the bottom. After racking, I have just a little under a gallon.
Ready for first racking.
I may only get a half gallon by the time this batch is racked and aged enough. So, I took some juice from the dregs and strained it to use for a hydrometer sample…I hope any “body” in the juice isn’t affecting the hydrometer’s measurement.
Taking hydrometer and temperature reading.
The hydrometer reading is 0.998 at 70F, so that is 0.999 corrected. With the OG of 1.073, that puts it at 9.71% ABV. It’s still on the border between cider and wine…not sure what will end up being. (Other than delicious, I hope!)
Racking with a little mesh bag on siphon.
Racked the mixed fruit cider to a 1 gallon glass carboy. I strained the dregs and took a hydrometer reading of 0.996@69F.
I’m thinking I may top off with Culligan bottled water next time I rack, so I have a gallon. Currently, it’s a little under a gallon…maybe 10% short? Looks good though and over 9% ABV, so a top-off won’t hurt it.
A little under a gallon of mixed fruit cider.
The Kombucha is coming along…looks like a pretty decent skin is forming…almost covering the surface. Now.let’s see if it thickens. The jug has a small neck, so I’ll need to figure out removing the SCOBY and find a new, more appropriate container.
Early SCOBY signs! Day 11.
Probably one of those 1 gallonlemonade/iced tea dispensers with the spigot. The smell is a little tangy…haven’t attempted a taste yet. I’m not sure whether this first batch is supposed to be drinkable or not. We’ll see when I remove the SCOBY…somehow.
Update 2/24/15: Okay, so, I’ve been been saving some of a hydrometer sample of the mixed fruit cider, in the refrigerator. I’ve been taking a little sip every couple of days. It has settled nicely and the flavor is not agressive, but it IS distinct from straight apple cider. The jug is looking good…still needs more clearing. I’ll let it go another week and rack it onto just enough clean water to top it off…should only take about 2-3 cups.
Now for the kombucha: pretty much “Wow”. I sanitized a turkey baster to retrieve a sample. (I need a new wine thief!) I had to nudge the SCOBY aside…it is definitely holding together as a solid raft. I may go ahead and go to the next batch soon! The sample that I removed was tart and tasted “lemony”. I’m not a huge tea fan, but this stuff is really good! Not much tea flavor…just a little. I’m glad I used green tea. So, thumbs up! Let’s see if it will continue with the next round.
