Freetail Brewing's Spirulina Wit
Host city: San Antonio, Texas

This probably isn't the first time someone's tried to push a green beer under a basketball fan's nose this week, but Spirulina Wit is the only one worth drinking.

We're not going to lie to you: This beer looks weird. Like grandma's-seafoam-bathroom-with-the-plastic-toilet-seat weird. The ingredient giving it that diluted-absinthe appearance -- the spirulina itself -- is a blue-green algae that dates back to the Aztecs and is used today primarily as a protein and dietary supplement.

Here, it's used as food coloring for the brewery's 4.2% ABV rye witbier. The combination of wheat, rye, coriander and orange peel still tastes like the cloudy yellow Belgian style that's gone mainstream with some help from MolsonCoors' Blue Moon and Anheuser-Busch InBev's Shock Top. It just looks a bit funky, but that's kind of the point.

It's a refreshing brew for marking the changing season, but it's also a big step up from that keg of light lager that the local pub spiked with green food dye to make more "Irish." The Spirulina Wit looks more like a green agave margarita and is just as welcome in warmer weather.
