Root Beer gets its flavor from the sassafras tree root or the sarsaparilla vine. Originally the root was brewed like a tea to make an extract, but now it is much easier to buy the extract ready made.


The root beer extract is mixed with sugar, yeast and water. If this mixture is placed in a tightly sealed bottle, the yeast will generate carbon dioxide at a high enough pressure to carbonate the water. You end up with fizzy, delicious root beer!
