LAUTERING Meaning and
Definition
-
Lautering is a term commonly used in the brewing industry, specifically during the beer-making process. It refers to the process of separating the grain solids from the liquid wort, which is a crucial step in the production of beer.
During lautering, the mash, which is a mixture of milled grains and hot water, is circulated and stirred, allowing for the extraction of sugars and other essential components. The grain particles are then separated from the liquid by passing the mixture through a perforated vessel called a lauter tun or mash tun. This vessel contains a false bottom or screens that retain the grain bed while allowing the liquid to pass through.
The lautering process typically involves multiple steps, including a mashout, where hot water is added to stop enzymatic activity and rinse the remaining sugars from the grains. The liquid wort obtained from lautering is subsequently transferred to the next stage, where it undergoes the boiling and fermentation processes, leading to the final product – beer.
Lautering requires careful control of temperature, flow rate, and the size and composition of the grain bed to ensure efficient extraction and clear separation of the liquid from the solid materials. It plays a crucial role in determining the quality and flavor profile of the resulting beer, as it influences the sugar levels, color, and mouthfeel.
Overall, lautering is a key step in brewing, essential for the successful separation of grain solids from the liquid wort, contributing significantly to the production of quality beer.
Etymology of LAUTERING
The word "lautering" originates from the German word "lautern", which means "to purify" or "to strain". In brewing, lautering refers to the process of separating the liquid wort (containing sugars, enzymes, and other substances) from the grain during beer production. The term was likely borrowed from German brewing practices and incorporated into the English language to describe this specific step in the brewing process.
