A standard 23 fl oz can of Peace Tea has about 23 mg of caffeine, roughly 1 mg per fluid ounce, according to Caffeine Informer. That is a light dose. A single shot of espresso runs around 65 mg, so a whole tallboy of Peace Tea sits well under half of one shot.
Why Peace Tea barely registers
Peace Tea is a discount canned iced tea from the Coca-Cola Company, and it is built to be sipped like soda, not slammed like an energy drink. The caffeine comes from real brewed tea, so the amount stays low and the flavor and sugar do the heavy lifting. Coca-Cola's line puts a ceiling on it: there will be no more than 60 mg of caffeine per 23 oz can across the range, and most flavors land far below that ceiling at the 23 mg mark.
Blends made with green tea, white tea, or a lot of fruit juice tend to sit at the lower end because there is proportionally less black tea in the can. The Sno-Berry flavor is the outlier on the low side, coming in at about 13 mg per 23 oz can. If you are caffeine-sensitive, or you are handing a can to a kid, that is the number that matters: this is closer to a cup of decaf coffee than to anything you would call an energy drink.
Peace Tea caffeine by flavor
Amounts below are per 23 fl oz can. Caffeine figures come from Caffeine Informer. Calories and sugar are pulled from the Coca-Cola Peace Tea product pages.
| Flavor (23 fl oz can) | Caffeine | Calories | Sugar |
|---|---|---|---|
| Razzleberry | 23 mg | 140 | 35 g |
| Just Peachy | 23 mg | 150 | 39 g |
| Caddy Shack (sweet lemon) | 23 mg | 160 | 38 g |
| Georgia Peach | 23 mg | Varies by can | Varies by can |
| Green Tea | 23 mg | Varies by can | Varies by can |
| Texas Style Sweet Tea | 23 mg | Varies by can | Varies by can |
| Sno-Berry | 13 mg | 150 | 36 g |
| Range ceiling (any flavor) | No more than 60 mg | - | - |
Peace Tea also sells 12 fl oz and 16 fl oz cans of the core flavors. Since caffeine scales with volume at roughly 1 mg per fluid ounce, a 12 oz can lands near 12 mg and a 16 oz can near 16 mg. Those are estimates from the per-ounce rate, not separately published lab numbers, so treat them as ballpark. The 23 mg and 13 mg per-can figures are the verified ones.
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.
How it stacks up behind the bar
If a customer asks whether Peace Tea will keep them up, the honest answer is no, not really. You would need to drink three full 23 oz cans to match one 12 oz cup of drip coffee, which runs around 95 mg. The bigger story on a Peace Tea can is the sugar. A 23 oz Razzleberry carries 35 g of sugar and a Just Peachy 39 g, so the crash people describe after one is far more likely a sugar swing than a caffeine spike. If you want the tea taste without the sugar load, the Zero Sugar flavors exist, though Coca-Cola does not publish a separate caffeine figure for them and they sit under the same 60 mg ceiling.
