Wort, , is the liquid extracted from the mashing process during the brewing of beer or whisky. Wort contains the sugars that will be fermented by the brewing yeast to produce alcohol.
In homebrewing, the malt-making step can be skipped by adding a malt extract to the grain tea — the mixture that results after grains have been steeped in the water. The wort is then boiled and the process proceeds as indicated below. (See Brewing for more details.)
Once the wort mixture has been created, it is then boiled, either whole or in part, in order to sanitize as well as extract the flavor and aroma from the hops, which are added to the wort at set times in two parts: the bittering hops are boiled for around an hour to an hour and a half, and the finishing hops are added toward, or after, the end of the boil. Hop cones contain resins, which provide the bittering and take a long boil to extract, and oils, which provide flavor and aroma, but evaporate quickly. Generally speaking, hops provide the most flavoring when boiled for around 15 minutes, and the most aroma when not boiled at all (i.e., added after the boil, a process called dry hopping.)At the end of the mashing, the hot wort is cooled to a temperature favorable to the yeast. Once sufficiently cooled, the yeast are added, or "pitched", to begin the fermentation process.
The adjunct grains which can be added to the malted barley include wheat, corn, rye, and rice. They are used to create varietal beers such as wheat beer and oatmeal stout, to create grain whisky, or to lighten the body (and cut costs) as in commercial, mass produced American-style lagers.
