What water should you use to brew good tea?

When it comes to exceptional tea, attention often focuses on the origin of the leaves, the altitude of the gardens, the expertise of the master producers, or the traditional processing methods.

The forgotten secret of a perfect infusion

One fundamental element is often overlooked: water.

And this is paradoxical when we know that a cup of tea is composed of more than 99% water.

You can own a rare tea from the Yunnan mountains, a sublime Oolong from the Wuyi Shan cliffs, or a precious white tea from Fuding... if the water used is unsuitable, the result in the cup will be disappointing.

Water is the primary carrier of taste. It reveals... or destroys.

Why does water quality so greatly influence the taste of tea?

Tea is a living and subtle substance.

Its aromas consist of extremely delicate molecules: floral, mineral, vegetal, fruity, woody, honeyed, or roasted notes.

Water that is too rich in minerals, especially limestone, will:

• crush the aromas
• make the infusion heavier
• accentuate bitterness
• reduce the finish
• mask the tea's natural texture

Conversely, water that is too pure or completely demineralized can produce a flat, uninspired infusion.

Balance is therefore essential.

In China, since the Tang dynasty, tea masters already attached great importance to water.

In his famous work The Classic of Tea, Lu Yu already wrote that mountain water was the noblest for preparing tea.

Mountain water: historically the best water for tea

Ancient Chinese tea connoisseurs preferred:

• mountain spring water
• stream water
• certain renowned well waters
• pure rainwater in certain regions

Why?

Because these waters were naturally balanced:

• low calcium content
• light minerality
• natural oxygenation
• smoother taste

The great producers of Pu-erh tea from Menghai or the tea masters of the Phoenix Mountains still use very soft local waters today.

What water to use at home to prepare your tea?

Fortunately, you don't need to go searching for a hidden spring in the Chinese mountains.

At home, favor:

1. Filtered water

A filtering carafe or filtration system helps reduce:

• chlorine
• metallic taste
• some of the limescale

This is often an excellent daily solution.

2. Low-mineral mineral water

Certain bottled waters are very suitable for tea tasting when they have low dry residue.

Look for:

• low calcium content
• low sodium content
• low overall mineralization

Waters like Volvic or Mont Roucous are often appreciated by tea lovers for their neutrality.

3. Absolutely avoid

• highly chlorinated water
• very hard water
• distilled water
• overly mineralized water

Some very rich waters are more suitable for wine than for tea.

How to tell if your water is bad for tea?

Some signs are unmistakable:

• white deposit in your kettle
• metallic taste
• tea that is more bitter than usual
• unexpressive aromas
• rough texture

If your tea seems "closed," the water may be to blame.

Each tea reacts differently to water

A delicate green tea like those from Huangshan will require very soft water.

A Wuyi oolong can tolerate slightly more minerality.

An aged Pu-erh sometimes reveals more depth with slightly more structured water.

Water then becomes a precise tool.

Just as a great chef chooses their ingredients, a tea lover chooses their water.

The great paradox of tea

Many invest in rare teas without ever questioning the water used.

It's like buying a fine wine only to mix it with industrial ice.

Tea deserves better.

At Le Meilleur Thé de Chine, we source rare teas from their origin, sometimes in the most remote regions of Yunnan, Fujian, or Guangdong.

But their true expression begins at home... with your water.

Conclusion: the first ingredient in your tea isn't tea

It's water.

Pure, balanced, and soft water can transform a simple infusion into a true sensory experience.

Before changing your tea, perhaps simply change your water.

Your cup will thank you.
