I will show you how to make homemade root beer!

Step 1: Ingredients

First, you'll need a pot of water (1 liter of water).
Second, add 6.2 mL of root beer extract and 0.12 grams of sugar into the water stir until it dissolves. The root beer extract will give it the root beer flavor, and the sugar will sweeten it so it's not bitter.

Step 2:

Now remove water from the flame, and add another liter of cold water. Let the water cool down for 5-10 minutes. Then add the yeast. The yeast in this process with continue to grow, and create the fizzy carbonated feel like regular soda.

Step 3: Bottling.

Time to bottle your root beer! I suggest using plastic bottles, but you can use glass. Although glass bottles can explode unless you refrigerate. Once you have your root beer bottled. It'll go through a process called fermentation. Fermentation is a metabolic process that converts sugar to acids, gases, and/or alcohol. It occurs in yeast and bacteria, but also in oxygen-starved muscle cells, as in the case of lactic acid fermentation. This process can take a week or two. It's good to check on your root beer. If it goes through fermentation too long it can become regular beer.
