Iced tea without the caffeine: which blends work cold

Iced tea is caffeinated by default. Almost every bottle, every restaurant pitcher and every recipe you will find starts from black tea, and a tall glass of it is a real dose. If you have cut caffeine, the iced tea aisle quietly stops being available to you.

It does not have to be. Herbal blends make excellent iced tea — better than hot, in a few cases — but the method is different and the blends that work are not the ones you would guess.

Never brew hot and pour it over ice

This is the mistake almost everyone makes. Hot tea poured over a glass of ice melts the ice, and you end up drinking something half its intended strength. It tastes thin and watery, and people conclude that herbal iced tea is thin and watery.

There are two methods that actually work.

Cold brew — the better one

Put the leaves or bags straight into cold water and leave them in the fridge for eight to twelve hours. No heat at any point.

Use roughly the same quantity you would for hot tea, or a little more: one bag per cup of water, or a heaped teaspoon of loose leaf. Strain it in the morning. It keeps about three days in the fridge, after which it starts to taste flat rather than fresh.

Cold water pulls out flavour compounds more slowly and more selectively, so what you get is rounder and sweeter, with less of the sharp edge. Fruit and floral blends in particular come out noticeably better this way.

Double-strength hot brew — the fast one

If you want it in ten minutes rather than overnight: brew at twice the usual strength in half the water, let it cool to room temperature, then pour it over ice. The melting ice dilutes it back to normal. Two bags per cup, or two heaped spoons.

The one rule is to let it cool before it meets the ice. Straight from the kettle onto ice is the mistake at the top of this page.

Which blends work cold, and which do not

Cold flattens a drink. Aromatics that carry a hot cup evaporate less and reach you less, so a blend that is delicate hot will be nearly absent iced. What survives is acidity, sweetness and fruit.

Work well cold:

  • Hibiscus — the strongest candidate in the category. Tart, deep magenta, and it holds its edge over ice better than anything else here
  • Fruit blends — berry, mango, watermelon, apple, citrus peel. Cold suits them; they read as fruit rather than as tea
  • Rooibos — naturally sweet without sugar, and it does not go bitter no matter how long it sits in the jug. The most forgiving thing you can cold brew
  • Mint — sharp and clean over ice, and it holds up better than most leaf

Do not bother:

  • Chamomile — its appeal is soft and floral, and cold removes almost all of it. It is not unpleasant iced, just faint
  • Chai and heavy spice blends — cinnamon, clove and cardamom are warming aromatics and go dull and slightly dusty cold
  • Anything you would put milk in — that whole category belongs in a hot mug

Sweetening, and when to skip it

Hibiscus genuinely needs something. It is tart enough that most people find it hard going unsweetened, and a little honey, agave or sugar syrup turns it into a proper drink. Add it while the tea is still warm if you are using the fast method, because sugar will not dissolve properly in a cold jug.

Rooibos and most fruit blends do not need anything. They are already sweet, and sweetening them makes them cloying. Try a glass before you reach for the syrup.

Two things worth doing

Freeze some of the tea into ice cubes. A jug of iced tea gets weaker as the ice melts, which is a slow version of the problem at the top of this article. Tea cubes dilute it with itself.

Put the fruit in the jug, not on the rim. Lemon, orange slices, cucumber, a few berries, a sprig of mint — left in the fridge for a few hours they change the drink. Perched on the glass they are decoration.

What is on the Iced shelf

We keep a separate collection for the eight that are worth cold brewing, rather than making you guess:

A note on timing: iced tea is treated as a summer drink almost everywhere, which is a northern habit. We ship from Florida, where it is drunk in February.

The general brewing rules, if you want them, are in how to brew herbal tea. And every one of these is caffeine-free because the whole shop is.
