Rice Hulls for Brewing are an all-natural lautering aid designed to keep the mash bed open and flowing during all-grain brewing. They are flavorless and colorless, allowing brewers to improve runoff without altering the beer’s taste, aroma, or appearance. Rice hulls are especially helpful in mashes containing high levels of wheat, rye, or oats, where stuck sparges are more common.
These hulls provide functional benefits by creating natural filtration channels throughout the mash. When used at typical rates of 2 to 5 percent of the grain bill, they help prevent compaction, reduce the risk of clogging, and allow wort to drain more efficiently. Their neutral composition ensures they contribute no fermentable material and do not affect body or clarity. This makes them useful in recipes ranging from hazy IPAs to wheat ales and rye-forward styles.
Rice Hulls for Brewing are cleaned and prepared for mash use while remaining fully natural and free from flavor-impacting compounds. Their lightweight structure integrates easily with any grain bill, supporting smooth lautering in batch sparge, fly sparge, or hybrid systems. Because they add no color, they are suitable for both pale and dark beers.
To use rice hulls, mix them evenly into the dry grain bill before mashing in. The hulls maintain open pathways that allow wort to move freely through the grain bed, improving runoff speed and reducing stress on the lautering system. They can remain in the mash throughout the brewing process and are removed naturally during spent-grain disposal.
Designed for brewers seeking consistent lautering performance, Rice Hulls for Brewing provide a simple, effective way to stabilize the mash and reduce runoff problems in a wide range of recipes. Their natural composition and predictable behavior make them a reliable tool for improving efficiency on brew day.
