Wet milling vs Dry milling
November 30th, 2021
At the store, we mill a lot of grain in a day! Milling the grains allows access to the malt contents for mashing. Malt milling is usually done dry, but did you know that malts can also be moistened for milling?
Humidifying the malts for milling has several advantages. Dry milling has the inconvenient of fragmenting the malts, which can cause difficulties when filtering the wort through them. Humidifying the malts generates fewer fragments and thus reduces filtration problems. In addition, the moisture added to the malts protects them from oxidation and increases the efficiency of our mash… And, let’s be honest, there is a lot less dust to collect!
Wet milling can be accomplished in different ways. A simple twin-roller crusher is sufficient for wet crushing. Wet crushing requires only one passage, while dry crushing may require 2 to 3 passages. Malts can be soaked before crushing. Malt can also be humidified directly during crushing. However, this approach requires more specialized equipment.
Here is a simple technique to use at home.
- Using a spray bottle, spray the grains to be crushed at a rate of 20 mL of water per Kg of grain.
- Stir the grains frequently to spread the water evenly.
- Let the grain absorb the water for 30 minutes.
- Crush the grains.
Easy filtration … Is it the end of rice hulls?
