The quick version: steep 4 tablespoons of Hibiscus Cooler in 4 cups of just-boiled water for 7 minutes, sweeten lightly, and pour over a full glass of ice. Ruby-red, tart like cranberry, and naturally caffeine-free. The full recipe card is just below, along with the honest answer on sun tea.
Why hibiscus makes the best iced tea
Hibiscus was built for ice. The same tartness that can read as sharp in a hot cup turns bright and thirst-quenching when it's cold, which is why hibiscus coolers show up in warm climates everywhere: agua de jamaica in Mexico, bissap in West Africa, karkade in Egypt. One flower, one global summer tradition.
Our Hibiscus Cooler blends whole organic hibiscus flowers with spearmint leaf and raspberry leaf, so the cup pours deep ruby with a cool mint finish. No caffeine at all, which makes it the rare pitcher the whole house can drink at 4 pm. If you want citrus in the glass instead of mint, Citrus Hibiscus leans on lemongrass and orange peel and ices just as well.
The two reliable methods
The fast way (10 minutes): brew hot and strong, then pour over a glass packed with ice. The double-strength steep means the melting ice lands the strength exactly where you want it. This is the method in the card below.
The smooth way (overnight): cold brew. Same ratio, cold water, 8 to 12 hours in the refrigerator. Cold water extracts more slowly and gently, so the tartness rounds off and the floral side comes forward. If you have ever found hibiscus too puckery, cold brew is your answer. Both methods, with ratios and times for any tea, live in our full iced tea guide.
So what about sun tea?
Here is the part most recipes skip. Traditional sun tea steeps a jar of tea in direct sunlight for hours, and the sun never gets the water hot enough to do what hot brewing does. The jar spends the whole afternoon in the temperature range where bacteria are happiest, roughly 70 to 130°F, which is why food-safety guidance has long recommended against classic counter-top sun tea.
The good news: what people love about sun tea is the gentle, slow steep, and a refrigerator cold brew gives you exactly that, just cold instead of warm. Same ritual, same mellow cup, none of the gamble. If you want the look of the sun-lit jar, brew it in the fridge and bring it out for the table.

Frequently asked questions
Is sun tea safe to make?
The classic method carries a real, avoidable risk: hours in the bacterial comfort zone without ever reaching a sanitizing temperature. A cold brew in the refrigerator produces the same gentle-steeped flavor safely, so that is the method we recommend and the one in this recipe's notes.
Does hibiscus iced tea have caffeine?
None. Hibiscus is an herbal infusion, not a true tea, so it is naturally caffeine-free, along with everything else in our caffeine-free collection. For the numbers on every cup, see our caffeine chart.
What does hibiscus iced tea taste like?
Tart and bright, in the neighborhood of cranberry juice, with a deep ruby color and, in this blend, a cool spearmint finish. Lightly sweetened, it lands somewhere between lemonade and berry juice. Unsweetened, it is crisp and bracing.
How long does it keep?
Three to four days, covered, in the refrigerator. The color holds; the mint stays fresh-tasting through about day three.
Can I make it sparkling?
That is exactly what our Hibiscus Lime Mocktail does: this same brew, fresh lime, and sparkling water. Find both blends and the rest of the summer pitcher lineup in the iced teas collection.
