Does Fresca have caffeine? No, and here is the full ingredient rundown

No. Fresca has 0mg of caffeine in every flavor. It is a caffeine-free citrus soda, and always has been. Coca-Cola confirms zero caffeine across the whole lineup on the official Fresca product page.

If you are reaching for Fresca late at night or handing one to a kid, you are fine on the caffeine front. The thing that trips people up is the assumption that any adult-tasting soda with a grapefruit bite must have a stimulant in it. Fresca does not. What it has instead is a load of citrus flavor and artificial sweetener doing all the work.

Why people think Fresca is caffeinated

Two reasons. First, it looks and drinks like a "serious" soda, not a kids' fruit pop, so people file it next to cola in their heads. Second, it is a Coca-Cola brand, and Coke and Diet Coke both carry caffeine, so guilt by association kicks in. Neither of those tells you anything about the recipe. Grapefruit and other citrus flavors do not naturally contain caffeine, and Coca-Cola never added any to Fresca. It launched in 1966 as a sugar-free, caffeine-free grapefruit soda and the caffeine number has stayed at zero ever since.

Fresca caffeine and nutrition by flavor

Every current Fresca flavor is caffeine-free, zero calorie, and zero sugar per the Coca-Cola product page. Here is the full rundown for a standard 12 fl oz can.

Flavor	Caffeine	Calories	Sugar
Grapefruit Citrus (original)	0mg	0	0g
Black Cherry Citrus	0mg	0	0g
Peach Citrus	0mg	0	0g
Blackberry Citrus	0mg	0	0g

Source: Coca-Cola Fresca product page. Zero calories is the reason all that sugar is missing. The sweetness comes from aspartame and acesulfame potassium instead of sugar.

For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. How caffeine affects you depends on your own tolerance and health, so treat these numbers as information, not advice.

What is actually in Fresca

The original Grapefruit Citrus ingredient list, per Coca-Cola, runs: carbonated water, citric acid, concentrated grapefruit juice, potassium citrate, aspartame, potassium sorbate (preserves freshness), acacia gum, acesulfame potassium, natural flavors, glycerol ester of rosin, potassium benzoate (preserves freshness), calcium disodium EDTA (to protect taste), and carob bean gum.

A few notes from behind the counter. The concentrated grapefruit juice is what gives it that real citrus tartness rather than a flat sweet-soda taste. Aspartame and acesulfame potassium are the two sweeteners carrying the zero-calorie load, which is worth knowing if you avoid aspartame for any reason. The glycerol ester of rosin and gums are there to keep the citrus oils evenly mixed instead of separating out. Nothing in that list is a caffeine source.

How Fresca compares to other caffeine-free sodas

Fresca sits in the same caffeine-free camp as most citrus and non-cola sodas. Sprite is caffeine-free, root beer is almost always caffeine-free, and the big exceptions are colas and the citrus outlier Mountain Dew, which is loaded with caffeine. If you specifically want a soda that will not keep you up, Fresca is one of the safe defaults. The difference is that Fresca is also zero sugar and zero calorie, where most root beers and regular Sprite are full-sugar.
