Brewer's spent grain: Products, Composition & Fertilizer

Brewer's spent grain (BSG) or draff is a food waste that is a byproduct of the brewing industry. It makes up 85 percent of brewing waste. BSG is obtained as a mostly solid residue after wort production in the brewing process. The product is initially wet, with a short shelf-life, but can be dried and processed in various ways to preserve it.
