Kombucha is rapidly gaining popularity these days, and mostly because it’s something you can make at home (more than can be said for sodas and expensive juices).

While the poor economy and worries about health and the environment have diminished the national thirst for soda and bottled water, sales of kombucha and other “functional” juices in the United States topped $295 million last year, up 25 percent over a two-year period, according to SPINS Inc., a market researcher.

It’s good to see more people finding out the benefits of kombucha and trying it out for themselves. When I started drinking it a couple of years ago (I believe first as a hangover cure), I was surprised at how focused it made me feel, more than coffee or normal tea. I encourage those who haven’t tried it to take it for a spin.
