In this issue of LRRD, we review the steps in the research that began with the demonstration that brewers' spent grains had prebiotic properties protecting cattle against cassava (cyanide) toxicity. This focused attention on the byproduct from artisan rice wine production, and the demonstration that at low levels (4% of the diet), it reduced enteric methane emissions by 20%. The final outcome was the simulation of the rice wine byproduct by simple yeast fermentation of polished rice (or cassava root).
