Hi Im Japanese home brewer and right now Im thinking of making a new recipe of Witbier but Im wondering whether I should add rice hulls to prevent a stuck mash as I will use flaked oats and wheat. If it so how much rice hulls should I use ? And which recipe is the best ? (Acutually I dont have belgian pilsner(2 Row),belgian pilsen, belgian wheat malt, belgian aromatic malt, belgian 2-Row pilsner malt so Is there someone who knows alternatives ingredients of them ?) and how can I go up mash efficiency ?
