When it is scorching outside, I reach for citrus soda fast. Sun Drop is one I still buy, but I count the caffeine instead of treating it like plain soda.
With caffeine, label reading matters more than the brand name.
That is why I check the sodas I actually drink and keep the dose math clear.
Yes. Sun Drop has caffeine, and that is the part I look at before I buy it.
Does Sun Drop Soda have caffeine? (It’s more than you think)
The short answer is yes, Sun Drop Soda is caffeinated.
If caffeine affects you the way it affects me, I count Sun Drop in the same budget as coffee or tea.
Knowing whether it is caffeinated is only half the job. I also care about the serving size I will actually drink.
Regular 12oz Can Sun Drop
A 12oz can of Sun Drop contains 64 mg of caffeine!
That puts it in coffee territory for me, not in the ignore-it category.
Now, just to give you a bit of context, the average cup of coffee– the go-to morning fuel for many of us –typically has around 95 mg of caffeine.
So when I drink a citrus soda like this, I think about the extra caffeine I am stacking onto the rest of the day.
It is less than many coffees, but not so little that I would dismiss it.
Regular 20oz Bottle Sun Drop
A 20oz bottle of Sun Drop packs a hefty 105 mg of caffeine!
A 20 oz bottle can edge past a standard cup of coffee, depending on the brew strength and the cup size you compare it with.
At that size, I expect the caffeine to be noticeable, especially if the day already includes coffee.
If I am already sensitive or I have had coffee earlier, I count it.

Sun Drop variations & caffeine levels compared
Once the caffeine part is clear, I separate the variants. The specific version matters more than the name on the front.
Sun Drop comes in more than one version, so I check the label first.

|---|---|---|
Sun Drop Regular | 64mg | 105mg |
Sun Drop Diet | 68mg | 114mg |
Sun Drop Cherry-Lemon | 64mg | 106mg |
Sun Drop Diet Cherry-Lemon | 68mg | 114mg |
Sun Drop Caffeine-Free | 0mg | 0mg |
Sun Drop Diet Caffeine-Free | 0mg | 0mg |
Overview of Sun Drop soda drinks
The history matters because recipes and ownership can change, so I do not assume an old description still matches the bottle on the shelf.
Sun Drop started in Missouri, created by Charles Lazier, who sold beverage concentrates.
He sketched the recipe on the road, and his son Charles Jr. turned it into a working drink at the bottling plant.
The Sun Drop trademark was registered on April 15, 1930, while historical accounts place the beverage’s conference debut in Washington, D.C., in 1951.
Initially called Sundrop Golden Cola, it was first sold mainly in the South.
It changed hands over time, including Crush, Procter & Gamble, Cadbury Schweppes, and now Keurig Dr Pepper.
New versions followed, including Diet, Cherry-Lemon, Caffeine-Free, and Diet Cherry-Lemon.

Taste
Sun Drop tastes sharp and citrusy. I get lemon first, then a sweeter orange-like edge, with enough acidity to keep it from feeling flat.
The variants change the drink in practical ways: Diet cuts sugar, Cherry-Lemon tastes fruitier, and caffeine-free versions, where available, keep the profile without the caffeine I am tracking.

Health benefits & drawbacks
I keep sodas in the occasional-drink category.
What matters to me is how a soda fits into the rest of my caffeine and sugar for the day.
Caffeine, a natural stimulant, is the source of these health benefits. One of the most popular effects of consuming caffeine is improved alertness, short-term recall, and reaction time.
This is why caffeinated drinks are often an excellent choice for an energy boost. On top of that, some studies suggest that drinking caffeinated drinks help lower the risk of depression.
Sun Drop has more than caffeine. The sugar and flavoring are part of the drink too, so I treat it as a soft drink, not a replacement for water.
Those ingredients are why it tastes the way it does, and also why I do not drink sodas mindlessly.
For a caffeine fix, I usually come back to coffee or tea because the dose is easier to read.

Caffeine in Sun Drop soda vs other beverages
Now that the caffeine in Sun Drop is clear, I compare it with other caffeinated sodas by serving size first, then by milligrams.
Sun Drop Caffeine vs Mountain Dew
Sun Drop versus Mountain Dew is where the numbers matter. On paper, Sun Drop comes out ahead, but I still read the serving size first.
Your typical 12 oz bottle of Sun Drop rocks a cool 63 mg of caffeine, while Mountain Dew rolls in with around 55 mg.
Sun Drop Caffeine vs Coke
Coke is the comparison I use most often because the size is familiar. A 12 oz bottle of Sun Drop has 64 mg of caffeine, while a Coke of the same size has about 34 mg.
That is roughly twice Coke’s caffeine, so I register Sun Drop as a bigger lift, not a dramatic one.

FAQs
Is Sun Drop Soda a good option for people who are sensitive to caffeine?
For me, it depends on what else I have already had that day. If coffee or tea is in the mix, I count Sun Drop against my total rather than treating it as free caffeine.
Can consuming too much caffeine from Sun Drop Soda be harmful?
That matters more as I get near the commonly cited 400 mg daily benchmark for most healthy adults, which I treat as a general guideline, not a personal target.
Is Sun Drop Soda gluten-free?
Sun Drop is often labeled gluten-free, but I would still check the current package if that detail matters, since formulations can change.
Where can I buy Sun Drop Soda?
You can find Sun Drop in many grocery stores, and it is also sold online through Amazon.
Conclusion
So the short version is simple: Sun Drop brings citrus flavor and enough caffeine to matter, especially next to Mountain Dew or Coke.
When I want a fizzy citrus drink and still want predictable caffeine, I check the variant, the bottle size, and the milligrams before I buy it.
