First documented in China more than 2,000 years ago, kombucha has recently achieved cult status in the United States, but what is it? What it is:  Kombucha is a delicious, effervescent beverage that's made by fermenting black tea and sugar. Over several days, a pancake-shaped mixture of friendly bacteria, yeasts, and enzymes, called a scoby, feeds on the sugar, creating a slightly fermented tonic. Why it's good for you:  Kombucha naturally contains probiotics, B-vitamins, and organic acids (acetic, gluconic, and lactic). According to Delicious Living, "Kombucha is purported to do everything from cure the common cold to boost energy levels to sharpen eyesight. Research has yet to prove these benefits, but because it is fermented, we know it works as a probiotic—much like kefir—and aids digestion. According to an analysis conducted by Information Resources LC, a company specializing in kombucha research, it contains glucaric acid (not, as is often claimed, glucuronic acid), which can help the liver detoxify the body." What does it taste like? Kombucha comes in tons of different flavors, but many describe the underlying flavor as tart (similar to apple cider vinegar) and slightly sweet.   How to get it:  Kombucha can be brewed at home, but because home-brewed kombucha may be at higher risk for contamination by unwanted microbes, you may want to stick with tea made by commercial manufacturers. Check out the tasty flavored tonics from Health Ade, Kevia, and more.
