A bottled Starbucks Frappuccino has between 45mg and 110mg of caffeine depending on the flavor and the bottle size. The full-size 13.7 fl oz Coffee flavor tops the lineup at 110mg, and the small 9.5 fl oz Vanilla sits at the bottom with 45mg, per PepsiCo's published product data. PepsiCo makes and bottles these under a partnership with Starbucks, which is why the exact numbers live on PepsiCo's product facts site rather than the Starbucks menu.
Every figure below was checked against the individual PepsiCo product listing for that flavor and size. This matters because a lot of caffeine charts online treat "a bottled Frappuccino" as one number. It is not. The gap between the strongest and weakest bottle in the same cooler is more than double.
Why the vanilla bottle has half the caffeine of the coffee one
The caffeine in these bottles comes almost entirely from the brewed coffee in the recipe, and the flavored versions trade coffee for milk, sugar, and flavoring. Plain Coffee is the most coffee-forward recipe, so it carries the most caffeine at 110mg per 13.7 fl oz bottle. Mocha lands right behind it at 105mg because cocoa contributes a little caffeine of its own. From there it steps down: Caramel at 90mg, White Chocolate Mocha at 75mg, and Vanilla at just 60mg in the same size bottle.
The oatmilk line runs lower still. Both the Caramel Waffle Cookie and Dark Chocolate Brownie oatmilk Frappuccinos list 55mg per 13.7 fl oz bottle, which makes them the lightest full-size options PepsiCo currently publishes.
Size matters as much as flavor. The 9.5 fl oz bottles are not just smaller pours of the same liquid at a proportional dose. The 9.5 fl oz Coffee lists 75mg, which works out to about 7.9mg per ounce, essentially the same concentration as the big bottle. So if you grab the small Mocha (70mg) expecting a light hit, you are getting nearly as much caffeine as a full-size White Chocolate Mocha (75mg).

| Mocha | 13.7 fl oz | 105mg |
| Caramel | 13.7 fl oz | 90mg |

A note on seasonal flavors: PepsiCo rotates limited runs like Pumpkin Spice and Peppermint Mocha in and out, and their product pages only stay live while the bottles are in production. When we checked, neither seasonal listing was up, so we are not quoting numbers for them. If you have one in hand, the caffeine content is printed on the label under the nutrition panel, which is the same place PepsiCo pulls its site data from.
If you go through these by the case rather than one gas station stop at a time, multi-packs on Amazon are usually cheaper per bottle than singles from a cooler.
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.
Practically, that means even the strongest bottle in this lineup is a moderate dose. Two 13.7 fl oz Coffee Frappuccinos put you at 220mg, still comfortably under that reference point, though the sugar adds up long before the caffeine does.

FAQ
Which bottled Frappuccino has the most caffeine? The Coffee flavor in the 13.7 fl oz bottle, at 110mg per PepsiCo's product listing. Mocha is a close second at 105mg in the same size.
Is the bottled Frappuccino the same as the blended one at Starbucks? No. The bottle is a shelf-stable coffee drink made by PepsiCo under license, with caffeine printed per bottle. The blended drink from the bar is a different recipe whose caffeine varies by flavor and cup size, which we break down in our Starbucks caffeine guide.
Do the oatmilk Frappuccino bottles have less caffeine? Yes. Both oatmilk flavors list 55mg per 13.7 fl oz bottle, half the caffeine of the regular Coffee flavor in the same size and the lowest of the full-size lineup.
