Sparge is a verb that refers to the process of rinsing or washing a substance, particularly in the context of brewing or chemical operations. It involves spraying or pouring a liquid, typically water, over a solid material to separate or extract soluble components.
In brewing, sparging is a crucial step in the production of beer. After grains (such as barley) have been steeped in hot water to extract sugars and other desirable compounds, the remaining liquid called wort needs to be separated from the spent grains. Sparging is performed by evenly distributing hot water over the grains, allowing it to flow through and collect all the remaining sugars from the grain bed. This process is essential for obtaining the maximum amount of fermentable sugars, which will eventually be converted into alcohol by yeast during fermentation.
In chemical operations, sparging is often used to remove or dissolve specific substances from a solid mixture. It involves applying a solvent or another liquid to wash out the desired component, leaving behind the unwanted materials. This technique is commonly employed in laboratory experiments, industrial processes, and environmental remediation.
Overall, sparging is a versatile method used in various fields to separate, extract, or dissolve components from mixtures by rinsing or washing with a liquid solution.
In brewing, to throw water upon in a shower of small drops, that it may percolate equally through a mass.

The word "sparge" traces its origins back to the Old English word "sparger" or "spergian", which meant "to sprinkle" or "to moisten". It is believed to be derived from the Middle Dutch word "sperghen" or the Old Norse word "spreggia", both meaning "to spurt out". Over time, the word "sparge" has taken on specific meanings related to brewing and the process of rinsing crushed grain with hot water during beer production.
