beerwort
Wort prepared by the infusion of malt with water, intended to be converted into beer.
beerwort: liquid sugar extracted from grain for fermentation
Beerwort is the sugar-rich liquid produced when hot water dissolves the soluble contents of crushed malt grain. This liquid, also called mash liquor or simply wort, becomes the fermentation substrate for beer production. The process extracts fermentable sugars (primarily maltose and glucose), amino acids, minerals, and other compounds that yeast will consume to produce alcohol and carbon dioxide.
The basic extraction involves infusing crushed malt at temperatures between 60 and 76 degrees Celsius, depending on the desired sugar profile and efficiency. Brewers typically use two main methods: single infusion mashing, where grain steeps at one temperature for 60 to 90 minutes, and step mashing, where temperature rises incrementally to modify enzyme activity and extract different sugar compositions. The ratio of malt to water affects wort strength, measured in degrees Plato (percentage dissolved solids by weight) or specific gravity. Most beers target worts between 10 and 15 degrees Plato.
The term wort comes from Old English and Germanic roots meaning infusion or herb tea; beerwort simply specifies that this particular wort is destined for beer rather than other fermented beverages. Historically, before the standardization of mashing procedures, wort quality varied wildly based on grain quality, water hardness, and empirical technique.
After mashing, brewers separate the liquid wort from spent grain solids through a process called lautering, using either a false bottom in a mash tun or a lauter tun. The collected wort then undergoes boiling, typically for 60 to 90 minutes, during which hops are added for bitterness, flavor, and preservation. Only after cooling to fermentation temperature does the wort become beer, once yeast is pitched and fermentation begins.
Problems with wort preparation directly impact final beer quality. Low mash efficiency reduces yield and increases grain cost per unit of alcohol produced. Excessive mash temperatures above 76 degrees Celsius can extract tannins from the grain husk, causing astringency. Water chemistry, particularly alkalinity and mineral content, influences enzyme function and final wort pH, which affects both extraction efficiency and yeast performance. Brewers therefore monitor water composition and sometimes adjust it chemically before mashing.
