wonderful rice hulls
"I have not used any of large bag yet but, used previous smaller batches from kegland. With 80 L bag, won,t have worry about running out for a long time. Rice hulls are a mashing saviour to prevent stuck mashes and improve recirculating wort flow. When using torrefied wheat or oats, necessary. Name one brewer that likes a stuck mash or sparge. Much better value per kg in sack ( as you call it ) cheers, Andy"
