And though there are a lot of different kinds, for the most part, they're all pretty healthy.

Kombucha is all the rage right now. Though the fizzy, sweet, fermented tea has been around for at least a couple hundred years (and possibly much longer), it seems like Americans and Europeans are just beginning to discover the probiotic benefits.

That, and it tastes pretty good, too.

The best part of Kombucha is that, while it sort of fits into that soda or beer slot in terms of fizzy drinks, it tends to be pretty healthy—and comparatively low in sugar and calories.

So for this week's Taste Test, Jaime and I tried five different kinds of kombucha. To keep it simple, we stuck to sampling original and gingery/spicy flavors only (there are a lot of kinds out there).

What we found? They're all pretty consistently healthy, though there are a wide range of flavors. We ended up liking GT's Living Foods Original Kombucha, giving it a solid four stars for flavor.

We also really liked Kevita's Master Brew ginger kombucha, which is very effervescent and has such a pleasant gingery taste that we felt it would be a great stand-in for traditional ginger beer, even in a cocktail like a Dark and Stormy.

And finally, we were a little divided on Buchi Fire Kombucha. The brand advertises the flavor as "cold pressed ginger, cayenne and beet," which "kindle digestion and energize." However, I personally got a strong floral impression from the beverage—I thought, while tasting it, that it was made with rose water. While it was definitely one of the more unique flavors we tried, it may be a good fit for anyone looking for a drink that's a little out of the ordinary.
