Lao Sen Answers Tea Questions (2): Is Cloudy Tea Broth a Sign of Bad Tea?

Tea Friend Asks: Is Cloudy Broth a Sign of Buying Bad Tea?

A tea friend sent a photo saying the newly bought tea brewed a cloudy broth, wondering if they had been ripped off. I said, don't worry—cloudiness in tea broth needs to be distinguished by type: some cloudiness is the tea's normal temperament, while other cloudiness indicates a problem with the tea.

First, Distinguish: There Are Several Kinds of Cloudiness

The "cloudiness" of tea broth comes in different forms and from different sources.

One type has fine particles floating in the broth, visible against light, which settle after a while. Another type is bright when first brewed but turns cloudy as it cools. A third type is dull and not translucent from the start, like leftover dishwater from the previous night. The first two are mostly harmless; the third requires caution.

Tea Hairs and Cold Clouding: The Tea's Normal Temperament

The buds and leaves of tender tea have a layer of fine fuzz called tea hairs. Spring-picked tender buds have many tea hairs; when hot water is poured, the hairs fall into the broth, making it appear cloudy—against light, they look like fine particles that settle to the bottom after a moment, and the broth clears again. This kind of cloudiness is actually a sign of tender tea, not a defect.

It's also common for tea to become cloudy when it cools: some substances in the tea clump together at low temperatures, making the broth cloudy. Reheat it, or warm it in a water bath, and it becomes clear again. Mountain folks call this "cold clouding." If you encounter these two types, drink with confidence; don't rush to discard.

Cloudiness Caused by Brewing Technique: Just Adjust Your Method

Many cases of cloudiness are caused by brewing. Pouring water too forcefully stirs the leaves violently, sending fragments swirling in the broth; shaking the fairness cup before pouring out the tea sends sediment into the cups. This kind of cloudiness looks "misty" but not dull.

It's easy to fix: pour gently, letting water run down the cup wall; don't shake the cup before pouring; for extra care, use a fine strainer. Once your brewing is steady, the broth will clear up.

Cloudiness to Truly Watch Out For: Dull and with Off-Flavors

The concern is the third type. If tea has absorbed moisture or been stored improperly, the broth will appear dull and gray, never translucent no matter how you brew. When you bring it close to your nose, instead of tea aroma, you smell mustiness, mold, or a damp cloth smell. At this point, regardless of whether it's from a famous mountain, if it smells wrong, let it go—no matter how reluctant you are, once it's spoiled, it's spoiled.

The most practical way to judge is in three steps: first, look at whether the broth is translucent; second, smell whether the aroma is clean; third, taste whether the flavor is proper. If the first two steps pass, occasional cloudiness is mostly the tea's normal temperament.

In the end, when tea broth is cloudy, first check if it's translucent and if it smells right. Good tea may occasionally be cloudy—don't wrong it; spoiled tea, even if clear, should not be kept. Remember: look at the color with your eyes, smell with your nose—if your nose says no, don't persuade yourself to drink it.
