Brewing & Homebrewing Terms

The fermentable mixture, usually a combination of grains and hops, from which alcohol or spirits can be distilled.

A container or brewing vessel designed to hold a mash at a constant or increasing temperature during the brewing process.

The Original Gravity (OG) of a beer is the specific gravity of the beer measured before fermentation has started.

at bottling time, it is the addition of sugar, such as corn sugar, to enable the yeast in beer to naturally product carbonation

a device used to measure the Specific gravity of liquids by measuring the degree to which light is bent as it enters the liquid sample.

a measure of the relative density of one material compared to another

the color system used by brewers to specify finished beer and malt color.

Used in extract brewing applications. It is the process of soaking grains (usually specialty grains) in water to extract color/flavor/aroma/body. Steeping differs from mashing in that there is no starch-to-sugar conversion.

The sugary liquid produced in the brewing process either by mashing malted barley and water or using extracts and water. Wort basically the "beer" before the yeast is added for fermentation.

A device, usually a construction of copper tubing, through which cold water can run thus rapidly cooling the wort mixture.
