Many people all over the world like beer. In many countries, the tradition dates back many centuries, making beer a major part of the culture. There are many different kinds of beer, categorized by the way it is brewed and what it is made out of. This makes beer one of the most widely complex beverages in the world. Ironically, though, the process for making the many different kinds of beers is very similar; one only need look inside a beer factory to see this.
MASHING
Inside a beer factory the first thing that needs to be done is mix and mash the grains with malt and water. In modern times, this is done in a stainless steel tank. Depending on the type of beer you are making, the grains could include barley, wheat, and rice (and probably others because of the variety of specialty brands). Everything is milled, mixed, and boiled down and natural enzymes are added to break the starch into sugars, which will ferment and generate the alcohol content. The mixture is then strained which separates the spent grain husks from a clear, sweet amber liquid called wort.
BREWING
Once the mixture is strained, the wort is sent to the brew kettles. Once there, the liquid is brought to a boil where natural hops are added (for lagers). This is the “spice” or “flavor” of the beer. Depending on the recipe and the variety of hops, this step will change the fragrance and flavor of the beer. Before the beer ferments, though, the wort is pumped through another vessel, which receives it and cools it to the necessary temperature for receiving yeast.

FERMENTATION
Up until this point, the process for brewing beer inside a beer factory is exactly the same no matter what you are brewing (give or take the hops that you select for the flavors you are looking for). However, the first (of three) difference(s) between lagers and ales (which are, essentially, the two basic kinds of beers), is which kind of yeast you use. During the fermentation process, the brewer adds yeast at this point.
Lagers are made with “bottom-fermenting” strains of yeast, which sink to the bottom of the tank and ferment there. This provides a clean, crisp flavor because the yeast does not affect the flavor of the grains, malt, and hops. Lagers ferment at colder temperatures and brew for a longer period of time.
Ales are made with “top-fermenting” yeast strains. Typically, the yeast has risen to the top of the tank during the fermentation process. Top-fermenting yeast does affect the flavor of the brew. Ales ferment at warmer temperatures and brew for a short period of time.
STORING / BOTTLING
After the yeast is added and the beer is fermented it is either stored or bottled. Inside a beer factory you will find a large assembly line where the beer is put into bottles (or cans or kegs) and then either stored or further sent to the distribution area where it is shipped out to warehouses, liquor stores, grocery stores, and pubs.
