Husk integrity can be improved by conditioning the grain, using an appropriately large mill gap, and using a 3-roller mill or a mill with fluted rollers. | Husk integrity can be improved by conditioning the grain, by using an appropriately large mill gap, and by using a 3-roller mill or a mill with fluted rollers. | ||

Malts that shatter tend to create more flour which can attribute to difficulties during lautering. The fine particles can fill in the spaces in the otherwise permeable bed causing a slowed or stuck lauter. These brittle specialty malts can typically be milled with a wider mill gap resulting in a larger particle size that will still allow for complete flavor and aroma extraction which is the primary function of these malts. Finding the balance of desired particle size starts with adjusting the mill gaps.<ref>Geurts J. [http://blog.brewingwithbriess.com/9-5-grind/ 9-5 grind.] Briess blog. 2018. Accessed 2020.</ref> | ||

Conditioning can help lower the amount of dust generated while milling. However, dust can still be created when measuring the grain. Wearing a mask can be beneficial for your health since breathing in grain dust is not so great.<ref name=mostra/> Thanks to COVID-19 you do have a mask, right? | ||
