Bag Size: 80L | 20Kg

Slater Farms' Rice Hulls are a must-have adjunct for any serious craft brewer. Our 80 litre bag of non-fermentable and non-GMO rice hulls are food grade and the perfect choice for all-grain brewing, aiding in lautering and helping to prevent stuck mashes.

Rice Hulls are the outer shell or husk of a grain of rice. Rice Hulls are normally removed from the grain of rice, and when used for brewing the hulls improve the filter bed of the mash to decrease the likelihood of a stuck mash. Rice hulls are non-fermentable, and provide bulk helping prevent the mash from settling and becoming stuck during the sparge. Rice hulls are particularly useful for recipes using high protein additives such as large amounts of wheat or flaked barley or oats or rye in the grist.

Brewing Use Guidance:

Rates of usage can vary with the percentage of adjunct grains, but in general, adding between 1% and 5% of total grist weight in rice hulls directly to the mash helps ensure better wort runoff rates and greater wort clarity.

In an all-grain brew Rice hulls act like makeshift springs. When adding them to your mash they will get in-between the wheat or flakes and prevent clumps forming. So picture them as little tiny springs making your mash fluffy rather than a big pile of goop! Rice hulls can be added directly to your mash and they add no flavor or colour to your beer, they are just an aid to help with preventing stuck sparges. If your recipe does not have a large amount of barley in it and has primarily wheat, rye, or flaked whatever then it is usually a good idea to use rice hulls because without them it turns into a big dough ball.

Why Slater Farms? Why Bio-Dynamic?

About Slater Farms

Slater Farms (Brett & Karen Slater) is the home of “Rainfed Rice” and is grown and milled on our farm in Northern Rivers, NSW.

Brett Slater, a local Bio-dynamic certified farmer with a passion for innovative sustainable farming moved to organic farming practices in 1998 and converted to Bio-dynamic growing in 2004.

Brett grew his first crop of dryland rice in 2009.

He then purchased and set up his own mill on the farm in 2010 to produce an all-down-the-line bio-dynamic grain.

Specialising in Bio-dynamic Farming

Bio-dynamic farming is a deeper form of organic farming that works on the fundamental principle that the farm is a living organism. It’s all about balancing the ecological inter-relationship of soil, plants and animals as a self-nourishing system without external inputs.

Bio-dynamic farming adheres to guidelines that are even more stringent than those required for organic certification. All artificial chemicals are excluded.

Made from 100% locally grown high quality Australian Rice.
