Walk down a tea aisle and every pack seems to say "tea": green tea, chamomile tea, hibiscus tea, berry tea. To a shopper this is harmless shorthand, but to a buyer writing a specification or briefing a private label run, treating all of it as one category is where mistakes start. Herbal tea, fruit tea and true tea are three different things with three different sourcing profiles, and knowing which is which changes what you should be asking a supplier.
Where "tea" actually comes from
Strictly, tea is the infusion made from the leaves of a single plant, Camellia sinensis. Black, green, white, oolong and pu-erh are not different plants; they are the same leaf taken through different levels of oxidation and processing, which is why they can carry a shared caffeine and tannin profile even though the cup looks and tastes nothing alike. Anything brewed from a different plant, however similar the ritual, is not tea in the botanical sense — a distinction that matters more to a buyer than to a drinker, because it governs caffeine content, tannin astringency and, in some markets, what the word "tea" is even allowed to appear on the label.
Tisane: the catch-all for everything that isn't tea
The correct umbrella term for a non-Camellia infusion is tisane, though "herbal tea" is the phrase most buyers and consumers actually use. A tisane can be built from flowers (chamomile, linden), leaves (mint), seeds (fennel), bark, root or a mix of several, and in TeraVella's own offer this category covers sage, chamomile, linden, mint, thyme and fennel among others — plants with a long history in Anatolian herbal use. None of it contains caffeine unless a caffeinated botanical such as yerba mate is deliberately included, which is one reason tisanes are positioned differently on shelf and in marketing than true tea.
Fruit tea: a tisane with its own rules
Fruit tea sits inside the tisane family but behaves like its own category. Rather than a single herb, it is usually built on a base such as hibiscus, rosehip or dried apple, with named fruit pieces and flavour layered on top for colour and identity. Because it relies on dried fruit rather than leaf or flower, it carries more residual moisture, is denser, and needs a bagging line and grammage set up for that material rather than for leaf tea. A buyer sourcing fruit tea is really sourcing a dried-fruit blend that happens to be packed the same way as tea.
