How to Make Root Beer With Dry Ice

Captain Arresto dives into the bubbly world of root beer. Using a simple essence, water, sugar, and a bit of dry ice magic, he shows you how to whip up a delicious homemade root beer in no time.

Root Beer Extract

1. Typically found in grocery stores or online. Check the label for recommended amounts.

Sugar

1. Regular granulated sugar; about 2 cups.
2. This can be substituted for honey, brown sugar or sugar substitute.

Water

1. Cold tap water; approximately 3/4 gallon (2.8L).

Dry Ice

1. You'll need about 3/4 pound or 0.35kg per batch.

Large Mixing Container

1. A food-safe plastic bucket or beverage dispenser works well.

Mixing Spoon

1. Long enough to safely stir the mixture.

PPE - Gloves, Tongs & eye protection.

1. For safely handling the dry ice.

Always use gloves or tongs when handling dry ice to prevent frostbite.

Do not seal the container tightly when using dry ice; the pressure from CO₂ gas buildup could cause the container to burst.

Ensure good ventilation while making the root beer.

1. Fill your container with cold water, leaving enough space for bubbling once the dry ice is added.

2. Add the root beer extract according to the package instructions (e.g., about 2 tablespoons/60ml/1 oz per 3/4 gallon, but check your brand's recommendation).

3. Stir in sugar until dissolved. Adjust sweetness to taste.

1. Break the dry ice into small chunks using a hammer (if necessary) while wearing insulated gloves.

2. Carefully add the dry ice chunks to the root beer mixture. Use tongs or gloves to avoid direct contact.

3. Stir gently as the dry ice begins to react with the liquid, creating a foggy, bubbling effect.

Allow the mixture to bubble and carbonate for about 5-10 minutes. Stiring as you wait.

Once the dry ice has completely evaporated, the root beer is safe to drink.

Serve - the root beer will be chilled from the dry ice.

Use cold water to help retain carbonation longer.

Serve immediately after the dry ice finishes bubbling for the best fizz.

Do not consume undissolved chunks of dry ice.
