Homebrewing is not difficult, but neither is it simple. There are just a few stages in the process of brewing your own beer. First, you soak malted barley in hot water. This releases the malt sugars, which you then boil with Hops. Once this mixture has cooled, you add yeast. Yeast starts the fermentation process, releasing CO2 and ethyl alcohol. Once this process is completed, you add a bit of sugar to the brew to create carbonation.
While this doesn't sound that difficult, each step in the process is subject to all kinds of variables. Here's where you will want to do your research. There are many resources online and in print to help you understand both the essentials and the nuances of this process, so that you can create a homebrew that not only satisfies your tastes, but that you would be proud to serve to your mates.
