The basic process of beer home brewing can be broken down into to steps starting with getting your ingredients, which consist of water, grains, yeast and hops. Then after the grains are crushed, the steeping of them begins. The steeping process is basically like making tea, the only difference is that the starches in the grains need to be converted into sugars that can be used, or fermented by yeast. So, basically, the entire home beer brewing process is converting sugars from barley or other grain malt then fermenting those sugars into alcohol and carbon dioxide through the beer fermentation process. That’s it.
