kombucha!

Kombucha is a sour, fizzy drink. Imagine a cranberry soda.

Here's how you make it:

  1. Beg, nag, and spam for a starter. They're a bit hard to come by.
  2. boil water (1qt)
  3. steep a few tea bags to make very strong tea (2 bags)
  4. add sugar (1/4c)
  5. cool to body temperature
  6. add kombucha "mushroom"
  7. add kombucha from a previous batch (1/2c)
  8. wait a week

The "mushroom" is an odd structure that kombucha creates. It's also called a "sponge" or "pancake", but it's none of these things. Some call it a "S.C.O.B.Y." (symbiotic culture of bacteria and yeasts), which really just means that we don't know what it is.

From what I've read, kombucha is a bit delicate. Weed organisms may take hold, making it go "off". The 1/2c of kombucha from the previous batch helps set the pH so that kombucha will dominate.

I put it in a wide bowl, put a few long strips of tape over the top, and draped a cheesecloth over it. The cloth allows air to flow in, but keeps out bugs which like the sugar.

Instructions say to keep it somewhere it won't get disturbed, so I used the guest bedroom. They say to start tasting it at 5 days, but I figured the guest room was cooler than the rest of my already cool house, so I let it go a full 10 days.

Today I tasted it (slipped a straw under the edge) and it was really, really sour. 10 days was perhaps a bit much. It was also very tasty.

So I decanted it & started up a new batch.

At first, my 3.5 year old refused to try it based on smell, but eventually decided to take a taste. My wife liked it from the beginning. I think it's delicious.

I'm making the above recipie at 1.5x the stated measurements. Making 1.5qt of kombucha / week just isn't going to cut it for a family of 3, I suspect. I will try to find a bigger bowl, and maybe get two batches going at once (1/2 week apart from each other, perhaps).

You can also put the kombucha in bottles & let them continue to ferment, which becomes more bubbly. I picked up some Grolsch bottles on ebay which I intend to do this in.

I used some good quality green tea, since I don't want caffeine. You can also use black tea & oolong tea. You can't use herbal tea, as kombucha wants to grow on real tea.

The starter you get comes in two parts: a mushroom and a small amount of fresh kombucha. It's possible to get started with just one if you don't have the other, but it's a bit risky. I'd be happy to share my kombucha with anyone who wants to come pick it up. I live near Microsoft in Bellevue, WA. You can also look for sources of Kombucha online

Well, this is interesting. I did a blog search for caffeine in diet coke and found your site. When I get some time I'll come back and find out where caffeine in diet coke appears and how it relates - if it even does. Take care - nice work.

Interesting blog. You make some good points. You might be interested in fruit and herbal tea. There's a vague connection to what's been discussed here.

Good read. I've also heard of people buying commercial Kombucha and using that as a starter since it has strands in it. Then you can grow your own mother. The person I talked to used "trilogy" from GT Kombucha.
