WhatsApp: +86 18838072829Heat water to 158F and put it in a spray bottle or watering can, and lightly spray the grains for 60 seconds, allowing excess water to drop off. Allow the malt to sit for a minute or two to absorb as much water as possible and then mill it. Reportedly this technique results in a slightly higher water content than steaming.
WhatsApp: +86 18838072829Wet milling. In contrast to dry milling, wet milling consists of grinding the soaked grain and then separating the grain chemical compounds (starch, proteins, fiber, and oil). Wet milling of mainly corn aims to extract the maximum possible amount of native or undamaged starch granules. Therefore starch represents the primary product of wet milling.
