Drinking out of a bucket of bacteria is scary, but I thought I would try out brewing my own kombucha anyway.
I don’t subscribe to any of the woo around the miracles of kombucha, but I do like the way it tastes. Summer is coming up and it’s my favorite beer alternative. Plus I have a hunch that home-made can be much better (and cheaper) than store-bought.
Here are my notes.
2019-04-03: Ordered equipment
After doing some shopping online, I came up with a list of kombucha brewing equipment.
2019-04-09: Received all the stuff.
As a sub-Prime™ citizen, I had ample time to practice the virtue of patience.
Once I got all this stuff, I cleaned out the jar/bottles using the bottle brush and a very mild soap that I use on my hands and dishes. People online will say soap is bad for the SCOBY, but I imagine whatever chemicals are in my glassware is worse.
Stupidly, I stored the kombucha starter in the refrigerator, which is completely unnecessary and probably slowed down my first brew.
2019-04-11: Started making my first batch.
I don’t have fancy purified water, so I opted to boil my tap water for 5-10 minutes to try to remove the chlorine. A quick googling suggests this might work.
I started by filling my 4 Qt sauce pan up with tap water, boiling it for 5 minutes, and letting it cool completely. I then dumped it into the glass jar.
I then refilled the 4 Qt sauce pan with water and brewed a strong sweet tea. For the sweet tea, I used 1 cup of sugar and brewed in 2 TBSP of strong black tea. After this cooled I dumped it into the glass jar as well.
Finally I added the SCOBY out of the fridge. It sank to the bottom. A bit neurotic from reading too much about kombucha failures online, I was a bit concerned about the pH of my solution. I didn’t want to buy tester strips so I opted instead to dump half a bottle of GT’s Kombucha (Original flavor) into the mix. It was also nice to taste the other half of the bottle so I would have a reference for what a good plain kombucha tastes like. That stuff was really tasty.
Supposedly in 7 to 10 days I’ll have a decent kombucha. Getting a bit excited! Will it mold? Lets find out!
2019-04-17: First inspection/taste.
Inspected my SCOBY after a week. It looks much larger and seems to have covered the entire air/liquid boundary. Looks normal; no visible mold. The original SCOBY seems to have started floating, maybe. But the solution is cloudy now.
Poured myself a shot glass. Taste is a bit sweet but watery. Maybe slightly carbonated. I don’t think it’s quite ready.
2019-04-21: Bottling day.
Shot glass today tastes both sweet and tart, but also a bit watery. Drinkable for sure. Seems like a good time to start stage two of fermentation.
I made several different flavors:
Left to right: plain, peach/pear, ginger/pear, blackberry/ginger, and lemon/black tea.
2019-04-22: Bottle burping.
I heard it was a good idea to try and release some carbonation to prevent the bottles from exploding. The middle 3 flavors had a ton of carbonation! The plain and Arnold Palmer had almost none.
I let the plain and lemon ones sit out for five days, and refrigerated the more fruity ones for after just two days. This is because I got tired of burping the fruity ones!
2019-05-03: Tasting notes.
All the kombuchas have been consumed. They were all tasty. The main issue was lack of fizzy-ness, which is surprising because the bottles practically exploded when I opened them. The taste is more like a fruity iced tea.
I drank the plain kombucha last. One surprise was that the plain kombucha tasted much nicer after the bottle fermentation. It actually had a tiny little SCOBY growing in it when I drank it.
2019-05-04: First “continuous” brew batch.
At the end of my first bottling, the SCOBY and roughly half the liquid remained in the container.
I added about 6 cups of sweet tea (1 cup of sugar dissolved in) and two cups of water back into the mix. This should produce another half gallon of kombucha.
I biked to the Vietnamese market and found some lemongrass, which I plan on using for flavor in this next batch. Tasting will be in 5 days this time.
Tasted the second batch and it already seems ready for bottling. The solution is tart but not quite vinegary. It tastes much richer and less watery than last time. The batch of tea I’ve added might have been a bit strong!
The flavors are plain, lemongrass, and more lemongrass.
2019-05-12: First taste
None of the bottles seemed to need much burping. I refrigerated and drank the plain kombucha today. It tastes very good, just like the GT’s original which I used to get started, but still a bit less carbonated.
I’ll try the lemongrass soon!
2019-05-19: Third bottling
I’ve been drinking the lemongrass and it is pretty good. The flavor is somewhat more subtle than I expected, and I think chopping it more finely would have made it more flavorful. I’ll try that next time.
The local grocery store had strawberries on sale; two pounds for $3. I made two with plain strawberries, and two with strawberries and ginger. They took on a nice pink color shortly after bottling.
