Barq's Root Beer Guide 2026 Caffeine Content History & Taste Comparison

The History & Heritage of Barq's Root Beer

Created in 1898 in Biloxi, Mississippi by Edward Charles Edmond Barq Sr., Barq's is one of America's oldest and most distinctive soft drink brands. Now owned and distributed globally by The Coca-Cola Company, Barq's is famously known by its long-standing slogan: "Barq's Has Bite!"

Why Barq's Is Different: The Caffeine Factor

Unlike most mainstream American root beers (such as A&W and Mug, which are completely caffeine-free), regular Barq's Root Beer contains caffeine. This gives Barq's a distinct energetic kick and sharper flavor profile:

  • Barq's Regular Root Beer: Contains approximately 22.5 mg of caffeine per 12-fluid-ounce (355 mL) can.
  • Diet Barq's / Barq's Zero Sugar: 100% Caffeine-Free.

The Ultimate Barq's Root Beer Float Recipe

Because Barq's has a bolder, more acidic bite, it makes the world's best root beer floats by perfectly counterbalancing rich dairy fat with premium vanilla bean ice cream.
