Describe the difference between mashing and lautering in the brewing process.

• A. Mashing is the fermentation stage; lautering is the same as mashing.
• B. Mashing mixes milled grains with hot water to convert starches into fermentable sugars; lautering separates the sweet wort from the spent grain.
• C. Mashing removes solids; lautering heats the mash.
• D. Mashing and lautering are the same step; no difference.

Answer: (B)

Mashing and lautering do two different jobs in turning malt into fermentable wort. Mashing involves mixing milled grains with hot water and letting enzymes in the malt convert the starches into fermentable sugars. This step creates the sugary liquid that will eventually become beer, and the temperature and time of the mash influence how fermentable or unfermentable those sugars become. Lautering comes after mashing and is all about separating. It uses the grain bed as a natural filter to drain the sweet liquid, called wort, away from the solid spent grains. Often, hot water is sparged through the bed to extract remaining sugars before the wort is moved on to boiling. That’s why the correct description matches: mashing converts starches to sugars with heat and enzymes, while lautering separates the resulting wort from the grain solids. The other ideas mix up processes (such as fermentation being the mash, or heating occurring during lautering) or treat them as the same step, which isn’t accurate.
