Used to improve the lautering of all grain brews when using large quantities of wheat and oats to help prevent stucked mash.

BREWFERM 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:

• Steam-sterilised

• Guaranteed free of organic and chemical contaminants

• Completely neutral flavour profile

• No more clogged filter beds

• Add during mash, using approx. 5% adjunct

When to use: whenever you expect problems lautering the mash:

• When using a lot of wheat malt (more than 50%) – wheat malt has no husks, which makes lautering difficult.

• When using a lot of unmalted grain (flakes)

• When using rye (rye has no husks either, but can lead to a type of "gel" forming on the grain bed). The filter can become blocked, with no more liquid able to pass through the grain bed (a.k.a. a stuck sparge). You can use Brewferm rice hulls to prevent this from happening. They make the filter bed less compact, allowing liquids to penetrate more easily.

Use: max. 5% adjunct. The simplest option is to add the rice hulls to the mash (especially if using a system that circulates the wort (Braumeister, Grainfather, Brew Monk etc.).
