7UP vs brewed black tea: which has more caffeine?

7UP vs brewed black tea: the numbers

Sources: 7UP's figure is verified in our 7UP caffeine guide against Keurig Dr Pepper / Caffeine Informer (source); brewed black tea's figure is verified in our brewed black tea guide against USDA FoodData Central (source).

The concentration gap is the striking part: brewed black tea packs roughly 588 times the caffeine per ounce. Sipping speed matters at that density; a 8 oz cup finished in minutes hits differently than the same milligrams spread over a slow cup.

Which one should you pick?

Pick 7UP when you want the lighter dose or a slower ramp, and brewed black tea when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.

For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
