This simple 15-minute homemade root beer is so fun and festive to make! Plus, it is the tastiest root beer in all the land. Truth.

Growing up, homemade root beer was a staple. We thought it was terribly exciting to watch the dark root beer bubble and pop while the billowy white fog spilled from the container.

His feelings about this homemade root beer? “Man, this is really, really good root beer.” I’ll take that.

Best Extract for Homemade Root Beer

A lot depends, of course, on what you use for extract. I’ve learned my lesson over the years that not all root beer extracts are created equal.

I won’t dissuade you from using widely-recognized brands out there, but I will tell you that my favorite extracts are Watkins root beer extract or Cook’s pure root beer extract. Both of these extracts are extremely delicious and have an intense but well-balanced root beer flavor.

The slight carbonation and extra chilliness from the dry ice makes me think I could get behind homemade root beer more than just once a year.

Precautions When Using Dry Ice

While homemade root beer is ridiculously easy and food-grade dry ice is completely safe to drink once it is melted, please keep in mind that there are definitely precautions to take when using dry ice.

  • Because dry ice is so cold, it can cause burns if touched directly so always use insulated gloves or tongs to transfer and take care when using it around small children in case they aren’t aware they shouldn’t touch the dry ice.
  • Make the root beer in a large, ventilated room or outside so the carbon dioxide doesn’t build up as it works its magic.
  • Dry ice evaporates quickly (a 5- to 10-pound block can evaporate within 24 hours; learned that the hard way when I opened my freezer and my stash of dry ice was just empty plastic bags!) so try to buy just the amount you need when you know you’ll use it quickly.
  • Store dry ice in a styrofoam cooler or a well-wrapped container to keep it cold longer, instead of in a commercial freezer – since it’s so cold, it can sometimes cause the internal thermostat to shut off.

This simple 15-minute homemade root beer is such a fun, festive drink for the fall and Halloween season, but it is definitely delicious enough to make year round!

The root beer doesn’t keep well if you want to make it days in advance. Over time, the carbonation dissipates, so it’s best to make this right before you want to enjoy it.

15-Minute Homemade Root Beer

4.61 stars (122 ratings)

Ingredients

  • 4 quarts cold water
  • 2-3 cups granulated sugar (depending on how sweet you want it; 2 cups is perfect for us)
  • 3 tablespoons root beer extract (see note)
  • 1-2 pounds food-grade dry ice broken into pieces (use the smaller amount if you want it to dissolve quickly and the greater amount if you want it to foam and bubble while serving)

Instructions 

  • In a large pitcher (I use glass), stir together the water, sugar and root beer extract until the sugar is mostly dissolved. Take a little taste to see if you need more extract or sugar.
  • In a well-ventilated area, carefully add the dry ice to the pitcher using insulated gloves or tongs and stir with a long-handled spoon so that the dry ice doesn’t stick to the bottom and sides of the container. The root beer will bubble and the dry ice fog will spill from the container (cool!).
  • Continue stirring until it is mostly melted, 10-15 minutes.
  • Ladle into cups, avoiding any large pieces of unmelted dry ice, and serve.

Notes

Dry Ice: while dry ice is completely safe to drink once it is completely melted in the root beer, please keep in mind there are a few safety precautions to follow when working with it: use insulated gloves or tongs to transfer – never touch it directly as it can burn, add it to the root beer in a well-ventilated area so the carbon dioxide doesn’t build up and don’t let children (or adults) inhale the fog spilling from the pitcher, and be careful when breaking it up into pieces.
How to Store: because dry ice evaporates quickly and doesn’t store well, it’s best to buy only what you need and use it as soon as possible (store it in a styrofoam cooler if not using it right away as it is best not to keep it in every day freezers).
Root Beer Extract: not all root beer extracts are created equal – some are definitely more potent and flavorful than others. I recommend Zatarains (harder to find these days), Watkins or Cooks brands.
