Could an ancient, climate-friendly crop be the future of beer?

Pierre Thiam and Garrett Oliver are on a mission to introduce brewmasters to fonio, a small and mighty west African grain

There's a certain magic to fonio, a tiny golden grain believed to be Africa's oldest cultivated cereal. The ancient grain's potential to solve pressing modern environmental and economic challenges inspired Pierre Thiam, the Senegalese-born chef, to become fonio's No 1 champion.

After rediscovering the grain and showing home cooks how easy to cook and versatile it is, now Thiam is introducing brewmasters around the world to what fonio can do in beer.
