<human>:  What is the process of making beer?
<bot>: The process of making beer typically involves several basic steps. First, the grains, usually barley or wheat, are ground and mixed with hot water in a large container called a mash tun. During this process, the starches are converted into sugars which will eventually ferment into beer Once the mashing is complete, the resulting liquid, called wort, is transferred to a large heating vessel called a boiler. Hops are then added to the boiling liquid, imparting bitterness and flavor to the beer. The beer is then cooled and transferred to a fermentation vessel, usually a large stainless steel tank, where yeast is added. The yeast feeds on the sugars extracted from the grain in a process called fermentation, producing alcohol and carbon dioxide. Finally, the beer is filtered, carbonated and packaged for consumption.
