Sparging
Sparging is an important brewing process where hot water is gently sprayed over grain to extract the remaining sugars after the main brewing step. Think of it like rinsing your coffee filter to get every last bit of coffee flavor out. Brewers use this technique to make sure they get the most value from their ingredients, which directly affects the quality and efficiency of beer production. This process might also be called "brewing runoff" or "grain washing" in some job descriptions.
