Brewing beer is both an ancient craft and a modern science, relying on a series of well-controlled steps to transform simple grains into a flavorful beverage. The process typically begins with malting, where grains—most commonly barley—are soaked in water to start germination and then dried to halt the process. This step develops the enzymes needed to convert starches into fermentable sugars.
Once the grain has been properly malted, it is milled, which simply means crushing the kernels to expose the starchy interior and ensure efficient extraction of sugars during the next steps.
How a mill works
After milling, the grain heads to the mash tun, where it’s mixed with hot water in a procedure known as mashing. Specific temperature ranges allow enzymes to break down the starches into sugars, creating a sugary liquid called wort.
The wort is then separated from the spent grains in a process called lautering. Typically, hot water is sprinkled over the grain bed to rinse out remaining sugars—this is called sparging
With the sugars extracted, the wort is moved to a kettle for the boil, which usually lasts around an hour or more. During this stage, hops are added at various intervals to impart bitterness, flavor, and aroma.
Following the boil, the wort must be cooled rapidly to prepare for the next crucial step: fermentation. In the fermenter, yeast is added (pitched) to the cooled wort, and over days or weeks, the yeast feasts on the fermentable sugars, producing alcohol and carbon dioxide.
Once primary fermentation finishes, the beer is often transferred to a secondary vessel or allowed to sit at cooler temperatures for conditioning. This stage refines flavors, reduces unwanted compounds, and clarifies the beer.
Finally, the beer is packaged in bottles, cans, or kegs and carbonated— either by adding priming sugar for natural carbonation in bottles or by force-carbonating in pressurized vessels.
Throughout these steps, strict attention is paid to temperature, sanitation, and timing, as each has a profound effect on the beer’s taste and quality. Whether you visit a commercial brewery or try your hand at homebrewing, this multi-stage transformation— from germinated grains to a freshly tapped pint—exemplifies how a combination of tradition, science, and creativity yields one of the world’s most beloved beverages.
