When all-grain brewing using large quantities of wheat, oats or other coarse grains, the filter bed can become easily clogged, which makes lautering very difficult. These steam-sterilised rice hulls are the ideal solution: these rice hulls do not affect the flavour at all and can be used to improve the lautering of the mash:

Professional users with a separate lautering tun can line the bottom with a layer of rice hulls approximately 2 cm thick, add water to cover, and then add the mash and start the lautering process.
