- Wort (pronounced as 'wirt' - rhymes with dirt) refers to the unfermented liquid extracted in the mashing of malted barley. The mashing process can also be called the worting process. After mashing, wort is referred to as sweet wort. You can also create sweet wort by combining liquid or dry extracts with water as one would in extract brewing. Once the hops have been added in the boiling stage, it is called hopped wort. Finally after the wort has been fermented it is called beer.
