If you're looking for a caffeine free tea, "decaf" and "herbal" get used like they mean the same thing. They don't. One is real tea with the caffeine mostly removed. The other was never tea in the first place. Knowing the difference changes what you should actually reach for at 9pm.
Herbal tea isn't technically tea
Herbal tea doesn't contain a single leaf of the tea plant, Camellia sinensis, which surprises a lot of people, since we're conditioned to think "tea" means one thing. Rooibos, chamomile, peppermint, hibiscus ... none of it comes from the same plant as black, green, white, or oolong tea. It's dried flowers, roots, bark, and herbs steeped in hot water.
In much of the world, this distinction actually shows up in the language. Outside the US, these blends are called "tisanes" or "infusions", which is a separate category from tea entirely. In the US, we just call everything "tea," which is convenient and also the reason this whole topic is confusing. Herbal blends are naturally caffeine-free, because there was never any caffeine-bearing plant in the mix to begin with.
Decaf tea is real tea, minus most of the caffeine
Decaf tea is different: it starts as actual Camellia sinensis, the same plant behind black and green tea, and goes through a process to strip out the caffeine afterward.
At August, we use CO2 decaffeination. No chemical solvents touch the leaf. Pressurized carbon dioxide pulls the caffeine out while leaving the tea's natural oils and flavor compounds intact, which is why a good decaf shouldn't taste like a flavor-stripped shadow of the original. It should taste like the tea it came from.
Decaf tea is not 100% caffeine-free, and it's worth being upfront about that. Even after processing, it retains roughly 2–5% of its original caffeine content. For most people that's a non-issue, it's basically a rounding error compared to a cup of coffee. But if you're caffeine-sensitive, pregnant, or avoiding it entirely for medical reasons, "decaf" and "caffeine-free" aren't interchangeable, and it's worth knowing which one you actually need.
Our decaf lineup
Right now we have three decaf black teas, all put through the same CO2 process:
Decaf Low Country
the bourbon sugar warmth of our original, decaffeinated
Decaf Dark Iris
peach, crème fraîche, and iris, minus most of the caffeine
Decaf Passage
hazelnut and chocolate, still rich, still decaf
Decaf or herbal — how to actually decide
If you want the ritual and flavor of real tea without much caffeine, choose decaf. If you want zero caffeine, period, or you like the flavor profile of an herbal blend better, go herbal, and our Top 10 Caffeine Free Teas Sampler is the easiest way to find your favorite — it's genuinely 100% caffeine-free, unlike decaf's 2–5%. Neither one is the "better" choice. Feel free to choose the right one for you..
