This is a small local brewery and the guide gives you a nice explanation of the steps in the brewing process. I like how he lets us know what takes place in each step and how the ingredients contribute to the outcome of the final beer product.
There are primarily 4 ingredients necessary to make beer and they are malted barley, yeast, hops, and water. There are other grains that can also be used and there are a number of different types of hops that can give the beer a different flavor and aroma.
So if you are new to this process and you are curious about just what is going on in the steps you need to take to make beer at home, then this nice short video will really help to clue you in.
