The first time I tried Mello Yello, the bubbles hit before anything else, then the sweet citrus flavor came through.
Since I was keeping my caffeine in check, I wanted the number per can, not just the flavor.
I use the caffeine number below the same way I do with coffee: as a quick check on how the drink fits into the rest of my day.
Does Mello Yello contain caffeine? (The quick answer)
In short, Mello Yello contains caffeine. Specifically, there are 51 milligrams of caffeine in a 12 fl oz can of Mello Yello.
That is roughly half a cup of coffee in ballpark terms, though coffee varies a lot by size and brew strength. On my scale, Mello Yello lands low to moderate.
The maximum daily recommended caffeine consumption level is 400 mg – knowing that Mello Yello has 51 mg of caffeine per can will help ensure you stay below that max.
Different varieties of Mello Yello & their caffeine level
I did not grow up seeing Mello Yello where I lived, so I was a little surprised by how many fountain options showed up when I looked for it.
I had seen cans of the original and Zero Sugar versions in supermarkets and convenience stores, but never Peach, Cherry, Orange, or Limeade.
A friend I was having lunch with had tried Citrus Twist, Raspberry Peach, and Strawberry Peach before, and those flavors sounded interesting enough to keep in mind.
Here is a quick breakdown of the caffeine in each flavor.
Flavor | Serving Size (fl oz) | Caffeine (mg) | Caffeine Strength | Calories |
|---|---|---|---|---|
Mello Yello Original | 12 | 51 | Low to medium | 170 |
Mello Yello Zero | 12 | 51 | Low to medium | 0 |
Mello Yello Cherry | 20 | 86 | Low to medium | 290 |
Mello Yello Peach | 20 | 86 | Low to medium | 290 |
Mello Yello Orange | 20 | 86 | Low to medium | 290 |
Mello Yello Limeade | 20 | 86 | Low to medium | 290 |

Mello Yello Original
Ingredients list
The original version is mostly about that sharp citrus soda profile, so I pulled the ingredients list to see what supports it:
Nutrition information
When I compare sodas, I pay attention to sugar and calories too, since they change how the drink feels as much as caffeine does.
The nutrition label for a 12 fl oz can of Mello Yello is:
Mello Yello Zero
Ingredients list
Mello Yello Zero Sugar skips the added sugar, so the ingredient list shifts while the flavor aims to stay close:

Caffeine in Mello Yello vs coffee and tea
For the 51 mg figure, I used a proportional estimate to scale it to an 8 oz coffee serving, which assumes a straight line between the two. It is a rough conversion tool, not an exact one.
Mello Yello’s 51 mg of caffeine is roughly on par with caffeine in matcha hot drinks.
On the charts I checked, it sits below typical brewed coffee figures and may overlap with some black and white tea figures; comparisons depend on serving size and preparation.
Beverage Type | Serving Size (fl oz) | Estimated Average Caffeine Content (mg) |
|---|---|---|
Coffee | 8 | 80-100 |
Black Tea | 8 | 47-90 |
Yerba Mate | 8 | 85 |
White Tea | 8 | 6-60 |
Green Tea | 8 | 20-45 |
Matcha | 8 | 35 |
Mello Yello | 8 | 34 |
When I look at soda caffeine, I care more about the mg per can than the flavor. That is the lens I used for Mello Yello next to drinks like Mountain Dew and Pepsi.
Comparing the caffeine in Mello Yello with other sodas
When I look at soda caffeine, I care more about the mg per can than the flavor. That is the lens I used for Mello Yello next to drinks like Mountain Dew and Pepsi.
Caffeine in Mello Yello vs Mountain Dew
A can of Pepsico’s Mountain Dew typically has 54 mg of caffeine per serving, which is only slightly higher than Mello Yello’s 51mg.
That feels moderate for soda, at least by soft drink standards.
Caffeine in Mello Yello vs Sprite
I usually reach for Sprite on a hot day when I want something caffeine-free, and it also works well with gin and fruit slices.
Knowing I can sip on Sprite well into the evening as it has 0mg of caffeine – this makes it a great alternative to drinking Mello Yello when out at an evening barbeque or restaurant meal.
Caffeine in Mello Yello vs Coke
Mello Yello is a Coca-Cola drink, so I set it beside a few other Coca-Cola brands to see where it landed.
Coca-Cola has around 34 mg of caffeine per 12 fl oz, which is below Mello Yello's 51 mg.
Caffeine in Mello Yello vs Dr. Pepper
I have always liked Dr Pepper, so I checked it here for comparison too.
If you are also a fan, it is worth noting that Dr. Pepper has 41 mg of caffeine per can, which is 10mg less than Mello Yello.
Caffeine in Mello Yello vs Pepsi
Pepsi sits lower too, at 38 mg per can, so it also comes in under Mello Yello.
FAQs
Can you reduce the caffeine in Mello Yello?
If I want less caffeine, the easiest move is a smaller pour or mixing it with a caffeine-free drink. It cuts the mg, though the soda loses some flavor.
Does Mello Yello offer a caffeine-free version?
The current U.S. Mello Yello product page lists Original and Zero Sugar, and both contain caffeine; it does not list a caffeine-free Mello Yello version.
Can you find Mello Yello in vending machines or fountain dispensers?
You can find Mello Yello in Coca-Cola Freestyle soda fountains across the US. You can locate your closest one on their website.
Conclusion
At 51 mg per 12 fl oz, Mello Yello feels moderate for soda and energy drink comparisons.
I treat it like any other soda and watch the total if I have more than one caffeinated drink in a day, especially since I notice caffeine more than some people do.
