Toast was launched three years ago in the U.K. by Tristram Stuart, an expert on the environmental and social impacts of food waste. His mission was to create a great beer with salvaged leftover organic bread — and he succeeded, creating the company's flagship American pale ale.

Stuart founded Toast as a way to raise awareness about food waste. Karen Kuhn, head of business development at Toast Ale USA, says he also wanted to create income for Feedback, an environmental organization started by Stuart that focuses on ending food waste at every level of the food system around the globe.

When Toast was launched, it had the support and endorsement of chef and author Jamie Oliver, and the beer quickly gained popularity in the U.K. and very soon may be available in Africa.
