Kombucha is pretty easy and inexpensive to make, and is supposedly pretty dang healthy. I prefer my homemade kombucha to any of the commercial examples that I have tasted -- it just seems much more flavorful and tart. There are a lot of different recipes and ratios out there in internet land to match different preferences in intensity and balance of flavor. I like mine with a nice acidic tang, and slight carbonation to add a bit of a bittering sensation to the sweeter backdrop of sugars. It can certainly put a pep in my step, even when coffee won't do the trick.
