Mashing
This is the first stage in brewing where the malted grains are flattened and soaked in warm water so that a malt extract is created. The mashed product is stored at a constant temperature so that the enzymes are capable of converting the starches in to fermentable sugars.
Sparging
In this stage, the water is filtered through the mashed product so that the sugars are dissolved. The dark, sugar-heavy liquid that is formed is called as the 'wort'. (pronounced like 'dirt' or 'word')
Boiling
In the third stage, the wort is then boiled with any other ingredients that are remaining so that the excess water is removed and the microorganisms are killed. This does not include the yeast. Then the hops, a flower used for stability and flavouring, is added at some point in the boiling stage.
Fermentation
In the fermentation stage, the yeast is added and the beer is left to ferment for some time. After the beer is fermented for the first time, some brewers ferment it for the second time also. The second fermentation lets the yeast and other particulate matter settle further.
Packaging
In this stage, the beer contains alcohol but not much carbon dioxide. However, the brewer does not have many options to add carbon dioxide here. Large-scale brewers force carbonation in to the bottles by directly adding carbon dioxide gas. The small-scale brewers add sugar or newly fermenting wort.
