Unpacking the Caffeine in Your Frozen Mountain Dew Treat
When you order a Mountain Dew slushie, such as a 7-Eleven Slurpee or a Taco Bell Freeze, you're essentially getting a frozen version of the classic soda. Since Mountain Dew soda contains caffeine, so does its frozen counterpart. The amount of caffeine, however, can differ depending on the retailer, the specific product name, and the serving size. Understanding the source and quantity of this caffeine is important for managing your daily intake and for those sensitive to the stimulant.
The Source of Caffeine: Soda Concentrate
Frozen carbonated beverages like the Mountain Dew slushie are made from a concentrated syrup that is mixed with carbonated water and frozen. The ingredients of the Mountain Dew concentrate itself include caffeine, along with other components like high fructose corn syrup and natural flavors. When this syrup is used to make a slushie, the caffeine is carried over into the final product. So, whether it's liquid soda or a frozen drink, the core ingredients remain the same, and caffeine is part of that recipe.
Caffeine Levels in Popular Mountain Dew Slushies
The caffeine content can vary based on the retail location. For example, product fact sheets from PepsiCo show differing amounts for various Mountain Dew Freeze varieties found at restaurants like Taco Bell. Similarly, 7-Eleven's Mountain Dew Slurpee has its own specific caffeine content. It's always best to check the nutritional information provided by the specific restaurant or convenience store where you are purchasing the drink. While the classic soda contains around 54mg of caffeine per 12 oz, the frozen version often contains slightly less due to the added ice and preparation process.
- 7-Eleven MTN Dew Slurpee: A 12-ounce serving contains 30mg of caffeine, according to reports from early 2025.
- Taco Bell Mountain Dew Baja Blast Freeze: A 12-ounce serving is reported to contain 36mg of caffeine.
- Circle K Mountain Dew Frozen Carbonated Beverage: An 8-ounce serving is listed with 20mg of caffeine.

Factors Influencing Caffeine in Your Slushie
Beyond the base soda, the final caffeine content can be affected by a few factors:
- Preparation Method: The ratio of concentrate to ice can influence the concentration of caffeine in your cup. A perfectly mixed slushie will have a consistent amount, but slight variations in preparation are possible.
- Flavor Variation: Some special edition or promotional Mountain Dew slushie flavors may have different caffeine levels than the standard version. Always check product information if you are concerned.
- Ice Dilution: While the ice is made from water, as it melts, it will dilute the drink, slightly lowering the caffeine concentration per ounce over time. This is a minimal effect but is worth noting for precision.
Who Needs to Pay Attention to Caffeine Intake?
For most healthy adults, the moderate amount of caffeine in a Mountain Dew slushie is not a major concern. However, certain groups should monitor their intake:
- Children and Adolescents: Younger individuals are often more sensitive to caffeine's effects, and its presence in sugary drinks is a concern for many health professionals.
- Pregnant or Lactating Women: Medical guidelines often recommend limiting caffeine intake during pregnancy and lactation.
- Individuals with Caffeine Sensitivity: Some people experience anxiety, jitters, or insomnia with even small amounts of caffeine.
Conclusion: The Frosty Truth About Mountain Dew Slushies
In short, there is definitely caffeine in a Mountain Dew slushie. The freezing process does not remove the stimulant from the base soda concentrate used to make the drink. While the concentration may vary slightly from the canned or bottled version due to the slushie-making process, a standard Mountain Dew slushie will contain a moderate dose of caffeine. Be mindful of the serving size and check the nutritional information from your specific retailer to know exactly how much you are consuming. For those who are sensitive or are managing their intake for health reasons, it's a detail worth remembering when choosing a frosty beverage. For a complete list of Mountain Dew ingredients, you can refer to the official PepsiCo product facts website.
More Insights on Your Slushie
How is a slushie made if it's carbonated?
Slushie machines freeze a mixture of concentrated flavored syrup and carbonated water while agitating it to create the distinct icy, smooth consistency. This ensures the carbonation is trapped in the ice crystals, giving it the soda-like fizz.
Does the caffeine content of a slushie change as it melts?
As a slushie melts, the ice (plain water) dilutes the concentrated mixture. This means the overall caffeine content remains the same, but the concentration per ounce will decrease slightly over time.
Are all Mountain Dew slushies the same?
No, Mountain Dew slushies vary by retailer and flavor. A Mountain Dew Slurpee from 7-Eleven will likely have a different ingredient and nutritional profile than a Mountain Dew Freeze from Taco Bell, including differences in caffeine content.
Is Mountain Dew Kickstart available as a slushie?
Mountain Dew Kickstart is a separate product line that is an energy drink and not typically offered as a standard slushie. Standard Mountain Dew or specific promotional flavors are used for slushie machines.
How does the caffeine in a Mountain Dew slushie compare to coffee?
An average 12-ounce cup of coffee can have over 100mg of caffeine, while a 12-ounce Mountain Dew slushie typically contains around 30-36mg. This makes the slushie a much lower-caffeine option than a standard cup of coffee.
Is the sugar content similar to the caffeine content?
No. While both are present, a Mountain Dew slushie's sugar content is generally much higher than its caffeine content. For instance, a 7-Eleven MTN Dew Slurpee can have 49g of sugar in a 375ml serving.
Can you order a caffeine-free Mountain Dew slushie?
No, because the slushie is made from the regular, caffeinated Mountain Dew concentrate. If you are seeking a caffeine-free frozen beverage, you would need to choose a different flavor or opt for a different type of drink.
