How much caffeine is in Barq's root beer float?

3 min read

A standard 12-ounce can of regular Barq's root beer contains 22 milligrams of caffeine. Because a root beer float is made with root beer and ice cream, a float prepared with regular Barq's will, therefore, contain caffeine, which often surprises those who believe all root beer is caffeine-free.

The Caffeine Breakdown: Why Barq's is Different

For decades, Barq's root beer has been known for its distinctive "bite." Unlike most other nationally distributed root beer brands such as A&W and Mug, which are caffeine-free, regular Barq's includes added caffeine as a standard ingredient. This practice dates back to the brand's early history, setting it apart in the crowded soft drink market. Coca-Cola, the parent company of Barq's, lists the caffeine content clearly on its product pages, affirming that a 12-ounce serving contains 22 mg of caffeine. The ice cream in a float, typically vanilla, does not contain caffeine, meaning the total caffeine level is entirely dependent on the amount of Barq's used.

Calculating the Caffeine in Your Float

Determining the total caffeine in your Barq's float is a simple calculation based on the root beer serving size. The ice cream's contribution is zero, so the amount is a direct reflection of the Barq's volume. A common float uses one can or a standard fountain pour, but larger or smaller servings can change the final number. Here is a breakdown of common serving sizes:

  • Standard 12 oz Can: A float made with a single 12-ounce can of regular Barq's will contain 22 mg of caffeine.
  • 20 oz Bottle: Using a 20-ounce bottle for a larger float will result in 36 mg of caffeine.
  • Fountain Drinks: This is where it gets tricky. Regular Barq's dispensed from a Coca-Cola Freestyle machine is caffeine-free. However, standard restaurant fountain machines can serve caffeinated Barq's, so it is always best to confirm with the restaurant staff.

Comparison Table: Caffeine in Popular Beverages

To put the caffeine in a Barq's float into perspective, here is a comparison with other well-known caffeinated and non-caffeinated drinks. This table highlights how Barq's provides a moderate, but not insignificant, amount of caffeine.

Beverage Serving Size Approximate Caffeine (mg) Notes
Barq's Root Beer Float 12 oz can 22 mg Caffeine is from the root beer only.
Barq's Diet Root Beer Float 12 oz can 0 mg A caffeine-free alternative.
Black Coffee 8 oz 95-200 mg Significantly higher caffeine level.
Regular Cola 12 oz can 30-40 mg Higher caffeine than Barq's.
Green Tea 8 oz 28-48 mg Slightly higher caffeine content.
Mug Root Beer Float 12 oz can 0 mg Made with caffeine-free root beer.
A&W Root Beer Float 12 oz can 0 mg Made with caffeine-free root beer.

How to Enjoy a Caffeine-Free Root Beer Float

If you are sensitive to caffeine or just want to avoid it, you have several excellent options for making a delicious root beer float:

  • Choose Diet Barq's: Opt for Diet Barq's or Barq's Zero Sugar. These versions are produced to have the same distinct "bite" flavor but without the added caffeine.
  • Select an Alternative Brand: Most other major root beer brands sold in the United States, such as Mug, A&W, and IBC, are naturally caffeine-free. Any float you make with these brands will have zero caffeine content from the soda.
  • Check the Fountain: If ordering from a restaurant, specifically ask if their root beer is caffeine-free. As noted, Barq's from a Freestyle machine is safe, but other fountain setups may serve the regular caffeinated version.
  • Read the Label: Always make a quick check of the ingredient label on any new brand you purchase. This is the surest way to confirm the presence or absence of caffeine.

Conclusion: Making an Informed Choice

While most root beer is caffeine-free, a Barq's root beer float is an exception to the rule due to the added caffeine in the soda itself. The total amount depends on the serving size of the root beer used, with a standard 12-ounce float containing 22 mg of caffeine. For those who need or prefer to avoid caffeine, delicious alternatives exist, including Barq's own diet version and floats made with other popular root beer brands. By being aware of these differences, you can easily customize your float to be a perfect, caffeine-free treat.
