A regular 16 fl oz Snapple iced tea, the classic glass bottle, carries about 37 mg of caffeine. Green tea runs lower at around 23 mg, the Half 'n Half blend sits near 17 mg, and the fruit juice drinks and rooibos flavors have none. Those numbers come from Caffeine Informer's Snapple breakdown.
Why Snapple caffeine is lower than you'd guess
Snapple leans on its "made from the best stuff on earth" image, so people assume the tea hits hard. It doesn't. The caffeine is naturally occurring from real black and green tea leaves, not dosed in like an energy drink, so a full 16 oz bottle lands around 37 mg. That is roughly a third of a cup of drip coffee. If you drink Snapple for the flavor and a mild lift, that is exactly what you get. If you are reaching for it as a coffee replacement on a slow shift, it will not carry you.
The pattern worth knowing: black tea flavors (lemon, peach, raspberry) cluster around 37 mg, the zero sugar versions of those same flavors run a hair higher near 38 mg, green tea sits lower near 23 mg because green tea leaves brew lighter, and anything built on fruit juice rather than brewed tea has zero. The Half 'n Half is diluted with lemonade, so it drops to about 17 mg.

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.
Two things trip people up. First, the diet and zero sugar teas are not caffeine-free. They actually edge slightly above the regular versions, near 38 mg, because pulling the sugar changes the recipe ratios, not the tea. Second, "tea" on a Snapple label does not guarantee caffeine. The rooibos in the Straight Up line is a herbal red bush, not a true tea leaf, so it reads zero. Same for the juice-based flavors that never see a tea leaf.

FAQ
Which Snapple has the most caffeine? The zero sugar black tea flavors, lemon, peach, and raspberry, top the lineup at about 38 mg per 16 oz bottle, just ahead of their regular sugar counterparts at 37 mg.
Is any Snapple caffeine-free? Yes. The Straight Up Rooibos and the fruit juice drinks like Black Cherry Lemonade contain zero caffeine because they are not brewed from true tea leaves.
Does diet Snapple have caffeine? Yes, and slightly more than regular. Diet and zero sugar teas run about 38 mg per 16 oz bottle versus 37 mg for the full-sugar versions, since the caffeine comes from the tea, not the sweetener.
