Today, let us talk about how beer is made..
Most people probably know there are four main ingredients in beer: the water, malt, hops and yeast. All of them contribute their own part in the beer.
The first step is mixing the crushed malt with hot water, this step called mash. This makes the malted barley turns into something to make good beer with. There are ways to make a lot of different styles of malt by vary the malting process. And you can get a whole range of colors and flavors from different malts, even something as dark as the burnt malt. It gives beer the black nutty, black color and roast flavor. All of the grain toasting, roasting and types of flavors, they together from different types of malt. All of the sweet flavors, comes from the malt. Those are large sugars the yeast want to ferment. They stay in beer and gives beer the sweetness of the body. And also all of the sugar the yeast want fermenting into alcohols, comes from the malt. So the amount of the malt to start with, primarily determines how strong the beer is going to get. The types of malt we choose to use, determines how dark beer will be.
The next ingredient is hops. Hops are added during boil, was to separated the sweet liquid from the grains, that liquid transferred in the kettle, bring out to the boil. The hops give primary bitterness to beer, as some compounds called ɑ acids in the hops, they do required as standard bill in boiling, in order to get that compounds out dissolved in the liquid. If you boil hops for that long, they boil a lot of aroma you want to get from hops perhaps. So generally there are mounts of hops conditions during the boil to get most bitterness in early conditions. You will get less bitterness in the late conditions. You can even add hops into cold beer in fermenters, it is called dry hopping. That gives most amount of aroma you want to get from hops, and non bitterness.
When the boil is done, the liquid has been cool down before it mix with yeast in the fermenters. You cannot see what is on inside of fermenters because it is big metal tanks. You can see how much yeast is in there during fermentation and how could it is. The sugars, they came out from the malt, turns into alcohol and carbon dioxide. There are 2 species of yeast are used; one is ale yeast, the other is lager yeast. You can get different flavor profiles from different types of yeast. The ale yeast ferment warmer and faster, produce more asters which give the finish beer for fruiting flavors. Lager yeast ferment cooler, slower and also require more maturation time after the end of fermentation, in order to get the flavors you are looking for from the lager yeast. Typically the ale will takes about a week to ferment and at least another week of cold aging. The lager usually takes a week & a half to two weeks for ferment and at least two weeks or longer of cold aging after the fermentation is done.
Once the fermentation is done, the beer is carbonated, then the beer is filled into bottles, kegs for selling.
