Cold Brew Tea Recipes: 5 Easy Fridge Infusions (No Bitterness)
Why Cold Brew Tea Tastes Better Than Iced Tea
Iced tea starts with a hot steep, and hot water is fast. It pulls out tannins and bitterness right along with flavour. Cold brew tea skips that problem entirely. Cold water extracts slowly, over several hours, drawing out the sweet and delicate compounds in the leaf while leaving most of the bitterness behind. The result is a smoother, rounder cup that tastes good even after it's been in the fridge for two days.
It's also close to effortless. There's no kettle, no timer standing over a mug, and almost no way to ruin it. Cold extraction is forgiving, so leaving your tea to steep an extra hour or two won't wreck the batch the way over-steeping in hot water does.
The Basic Cold Brew Tea Ratio
Every recipe below builds on the same starting point:
- Loose leaf tea: 1 to 1.5 tablespoons (about 2–3g) per 250ml (8oz) of cold water
- Water temperature: Cold or room temperature, straight from the tap or filter
- Steep time: 2–4 hours for green and white tea, 6–8 hours for oolong, 8–12 hours for black and herbal tea
- Fridge, always: Steep covered and chilled. It's more consistent than a countertop steep and there's no food-safety guesswork
The one habit worth building: pull the leaves out once steeping is done. Cold extraction is slow but it doesn't stop, and tea left sitting in its leaves for days will eventually turn bitter too. This is really the only reason a dedicated cold brew vessel is worth having over a jar. Something like the Hario Filter-In Bottle has the mesh filter built into the stopper, so you steep and strain in the same container and never handle a soggy tea bag or a separate infuser. For bigger batches, the Hario Filter-In Carafe does the same thing at a full litre, which is the difference between making tea for yourself and making a jug for the whole fridge.
5 Cold Brew Tea Recipes
1. Classic Cold Brew Green Tea
The easiest place to start, and the one most likely to convert a green-tea skeptic. Cold extraction strips out almost all the grassy bitterness that puts people off.
- 2 tbsp loose leaf sencha or gunpowder green tea
- 750ml cold water
- Steep: 3–4 hours in the fridge
Serve straight over ice, or with a few slices of cucumber dropped in for the last hour of the steep.
2. Hibiscus Mint Cooler
Caffeine-free and genuinely refreshing. Hibiscus brings tartness and colour, mint keeps it from tasting one-note.
- 1.5 tbsp dried hibiscus
- Small handful fresh mint leaves, lightly bruised
- 750ml cold water
- Steep: 6–8 hours
Good with a spoon of honey stirred in after straining, or a splash of sparkling water to serve.
3. Peach Oolong
Oolong's natural stone-fruit notes make this one taste like it has fresh peach in it even before you add any.
- 2 tbsp loose leaf oolong
- 2–3 thin slices fresh or frozen peach
- 1 litre cold water
- Steep: 6–8 hours
This is the one worth making a full litre at a time. The Filter-In Carafe's wide mouth makes it easy to drop the peach slices in and fish out the filter basket once it's done steeping.
4. Chamomile Lavender (Caffeine-Free)
An evening tea that doesn't lose its calm, floral character to cold extraction the way it can to boiling water.
- 2 tbsp dried chamomile flowers
- 1 tsp dried culinary lavender
- 750ml cold water
- Steep: 8–10 hours (overnight works well)
Best on its own, unsweetened, with a lot of ice.
5. Ginger Peach Black Tea
A bolder, more full-bodied option for anyone who wants their cold brew to still taste like tea.
- 2 tbsp loose leaf black tea (Assam or Ceylon)
- 3–4 thin slices fresh ginger
- 750ml cold water
- Steep: 10–12 hours
Strain and serve over ice with a thin peach wedge on the rim.
What to Brew It In
Any covered jar in the fridge will make cold brew tea. What changes the experience is straining. A built-in filter means you steep, strain, and serve from one vessel — no muslin bags, no pouring through a sieve at 11pm. Two options worth knowing about:
- Hario Filter-In Bottle (750ml) — sized for one to two servings, made from Hario's heat-resistant glass with a mesh filter built into the stopper. Good for a single-tea, single-day brew.
- Hario Filter-In Carafe (1000ml) — a full litre, wide-mouthed enough to drop in fruit or herbs, and built to share. This is the one for batch-brewing on a Sunday to drink through the week.
Both are made in Japan, dishwasher safe, and designed so the filter never leaves the tea sitting in a separate bag or basket once you've moved it to the fridge door.
FAQ
How long should you cold brew tea?
Green and white teas need the least time — 2 to 4 hours. Oolong sits in the middle at 6 to 8 hours. Black and herbal teas benefit from a longer steep, 8 to 12 hours, which is why an overnight brew works well for those.
Can you use tea bags instead of loose leaf?
Yes — use 1 to 2 tea bags per 250ml of water and follow the same steep times. Loose leaf generally gives a fuller flavour since the leaves have more room to unfurl in cold water.
Does cold brew tea have less caffeine?
Usually, yes. Cold water extracts caffeine less efficiently than hot water, so a cold brew tends to be gentler even at a longer steep time. Exact caffeine content still depends on the tea type and how much leaf you use.
Do I need a special pitcher to cold brew tea?
No — a jar with a lid works fine if you strain the leaves out through a sieve when steeping is done. A filter-in bottle or carafe just removes that extra step, since the mesh filter is already built into the vessel.
