Have you ever brewed green tea and noticed lots of tiny floating hairs in the liquor? Or opened a bag of tea and found a thin fuzzy layer stuck to the inside that almost looks like mold? Is it bad?

In many cases, the opposite is true. What you’re seeing are tiny hairs naturally shed from young tea buds, known in Chinese as “cha hao” (茶毫).

Some tea varieties naturally develop a layer of soft white fuzz on their buds when they’re young. As the leaves mature, the hairs gradually fall away, and the leaves become smooth. Since many green teas are made from very young buds and leaves, these fine hairs are still present during processing.

While the tea is being shaped and dried, the leaves constantly rub against each other and against the processing equipment. Some of the tiny hairs detach and stick to the surface of the tea, while others gather together into small off-white fuzzy clumps.

Before packaging, the more obvious clumps are usually removed during sorting.

Others, because of static electricity, some of these hairs can also stick to the inside of the tea bag or package, creating a fuzzy layer that can easily be mistaken for mold.

As long as you don’t have a specific allergy to tiny hairs, they’re generally completely safe to drink.

An easy way to tell the difference between tea hairs and actual mold is simply to brew the tea. If the aroma smells fresh and pleasant, without any sour, musty, or damp smell, the tea is usually perfectly fine.

Over the past few days, I’ve been trying different fresh Tieguanyin samples from tea farmers across Anxi, hoping to find one that feels right for everyday drinking.

Some teas greet you with floral aroma right from the first sip. Others start beautifully in the first infusion, but by the second steep, a strong grassy note suddenly appears.

Even within the same light-aroma style Tieguanyin, the processing makes a huge difference.

When the shaking process( oxidation ) is done a little longer, the aroma becomes noticeably richer and more lasting. The tea soup also feels fuller, with better endurance across multiple infusions.

On the other hand, teas with shorter shaking processing often lose their aroma quite quickly after the first steep. The grassy character becomes more obvious, and the tea feels less durable overall.

I also learned how much sun-withering can affect the final aroma. A few samples smelled softer and slightly muted because they were made during rainy weather and withered indoors instead of under sunlight. From what I’ve heard, Tieguanyin made with proper sun-withering usually has a much brighter, more expressive, and longer-lasting aroma.

Finding the right tea really is a long process. Every sample feels a bit like opening a blind box, but that’s also what makes it fun.
