How Beer is Made
Written By Bhabindra Thapa
Beer is made from four basic ingredients, barley, water, hops, and yeast idea is to extract the sugars from grains [usually barley] so the yeast can turn it into alcohol and Co2, creating beer.
1 MALTING
The brewing process starts with grains, usually barley (although sometimes wheat, rye, or other such things.)The grains are harvested and processed through a process of heating, drying out, and cracking The main goal of malting is to isolate the enzymes needed for brewing so that's ready for the next step.
2 mashing
The grains then go through a process known as mashing, in which they are steeped in hot not but boiling, water for about an hour, sort of like making tea, this actives enzyme in the grains that cause it to break down and release its sugars. once this is all done you drain the water from the mash which is now full of sugar from the grain. This sticky sweet liquid is called wort. its basically unmade beer, sort of like how the dough is unmade bread.
3 Boiling
The wort is boiled for about an hour while hops and other spices are added several times.
what are hops? Hops are the small, green cone-like fruit of a vine plant. they provide bitterness to balance out all the sugar in the wort and provide flavor. they also act as a natural preservative, which is what they were first used for. (for more info on hops take a look at our article on the subject )
4 Fermentation
once the hour-long boil is over the wort is cooled strained and filtered it's then put in a fermenting vessel and yeast is added to it. At this point the brewing is complete and the fermentation begins the beer is stored for a couple of weeks at room temperature {inthe case of ales} or many many weeks at the cold temperatures { in the case of lagers} while the yeast works its fermentation magic. Basically, the yeast eats up all that
sugar in the wort and spits out CO2 and alcohol as waste products. (For more
info on the difference between ales and lagers check our article here.)
5. Bottling & Aging
You’ve now got alcoholic beer, however, it is still flat and
uncarbonated. The flat beer is bottled, at which time it is either artificially
carbonated like a soda, or if it’s going to be ‘bottle conditioned’ it’s
allowed to naturally carbonate via the CO2 the yeast produces. After allowing
it to age for anywhere from a few weeks to a few months you drink the beer, and
it’s delicious!
