Tea Temperature and Infusion Time — A Practical Guide

Water temperature and infusion time determine whether tea reveals freshness, sweetness and aroma or becomes flat and harsh. There is no single universal value for every dry blend. Delicate leaves need a gentler approach, while substantial fruit and herbs require hotter water and more time.

In brief: begin white and green teas at around 80°C, black teas at 90–96°C, and fruit and herbal infusions at 95–100°C. The instructions for a particular composition always take precedence over a general table.

Tea temperature and infusion time table

Type	Temperature	Time	Starting proportion
White Tea	75–85°C	2–4 min	2–3 g / 200 ml
Green Tea	70–85°C	2–3 min	2–3 g / 200 ml
Black Tea	90–96°C	3–5 min	2–3 g / 200 ml
Fruit and herbal infusion	95–100°C	5–10 min	4–6 g / 250 ml

These values are starting points. Leaf size, the quantity of additions, water hardness and the desired intensity may require adjustment.

Why does temperature matter so much?

Hot water dissolves flavour and aroma compounds more quickly. This is beneficial while extraction remains balanced. Excessive heat can rapidly draw out bitterness and astringency, particularly from more delicate green and white leaves.

A lower temperature does not automatically mean a weak infusion. With the right amount of tea, it reveals sweetness, vegetal notes and a soft texture without a sharp finish.

White tea: 75–85°C, 2–4 minutes

White teas can be subtle, which is why boiling water can easily obscure their nuances. Begin at 80°C and three minutes. If the infusion is too delicate, extend the time by 30–45 seconds rather than reaching immediately for boiling water.

Japanese Cherry is a composition of white Pai Mu Tan and green Sencha with fruit and flowers. The presence of two delicate bases calls for a careful temperature. You will find more detail in our guide to white tea — flavour and brewing.

Green tea: 70–85°C, 2–3 minutes

Green tea responds particularly clearly to temperature. If it is bitter, first lower the temperature or shorten the time. In fruit compositions, the aroma of the additions does not change the needs of the tea base itself.

For Mango & Orange begin at around 80°C and two to three minutes. Refine the final parameters for your own cup and according to the instructions on the pack. You can also read our complete guide to how to brew green tea.

Black tea: 90–96°C, 3–5 minutes

Black tea needs hotter water to develop depth, but time still matters. Finer leaves and flavoured compositions are worth tasting after just three minutes.

Classic Earl Grey should retain a balance between the structure of black tea and the citrus aroma of natural bergamot oil. Ginger & Orange contains ginger, apple, orange and calendula, so it may need slightly more time for the additions to open fully. A useful trial range is 90–95°C and 3–5 minutes.

Fruit and herbal infusion: 95–100°C, 5–10 minutes

Fruit, peel, flowers and herbs are usually more substantial than tea leaves and need stronger extraction. A longer infusion develops colour and flavour, while the risk of characteristic tea bitterness is lower if the composition contains no Camellia sinensis.

Raspberry & Linden contains, among other ingredients, hibiscus, rose, elderflower, linden blossom, raspberry and blackcurrant. Begin at around 95°C and 6–8 minutes, then adjust the intensity.

How can you reach 80°C without a thermometer?

A thermometer gives the greatest consistency, but it is not essential. After boiling the water:

1. pour it into a cool jug,
2. wait for around two to three minutes,
3. only then pour it over the delicate leaves.

The rate of cooling depends on the vessel, volume of water and room temperature, so this is an approximate method. If you drink green and white tea regularly, a temperature-controlled kettle or a simple thermometer will make consistency easier.

Should the vessel be warmed?

A warm teapot limits the sudden drop in temperature when water is poured in. This matters more with small servings and heavy ceramics. Simply rinse the vessel with hot water, pour it away and only then add the leaves.

Do not overheat thin porcelain or glass, however. The aim is stability, not the highest possible temperature.

What should you change when the flavour is not right?

• bitter or harsh infusion: shorten the time or lower the temperature,
• infusion too weak: add a little more tea or extend the time slightly,
• the aroma is right but the flavour is flat: check the freshness of the water and your storage method,
• successive cups grow increasingly strong: remove the leaves when the infusion is complete.

Frequently asked questions

Must water be boiled before it is cooled?

You can heat fresh water directly to the required temperature. If your kettle has no temperature control, boiling and briefly cooling it is a simple method at home.

Does a longer infusion produce more aroma?

Up to a point. Beyond it, intensity can turn into bitterness and astringency. A slightly larger portion of tea with controlled timing often gives a better result.

Can every tea be infused again?

Many loose-leaf teas allow a second infusion, but not every composition retains the same amount of aroma. Assess each subsequent infusion on its own merits and do not expect an identical profile.

In summary: a table makes it easier to begin, but the best parameters emerge through attentive comparison. Note the amount of tea, temperature and time — after a few trials, you will find your own standard.
