It takes good ingredients to make good beer—grain, yeast, hops, a dash of honey or a squeeze of fresh cherries to add subtle flavor. This month more than two dozen breweries in Arizona tried out a new ingredient: purified wastewater. The Pure Water Brew Challenge raised awareness about water reuse and also inspired some tasty new beers. KNAU’s Melissa Sevigny went to local Flagstaff brewery Wanderlust, for our segment Eats and Beats: stories about food and music.

Hurricane Harvey is expected to be one of the costliest natural disasters in U.S. history. Researchers at Northern Arizona University specialize in mapping how local climate events affect the national economy. They say Harvey’s influence on food and fuel prices could be felt for months. KNAU’s Melissa Sevigny spoke with lead researcher Ben Ruddell.
