You’re probably envisioning a radiant, bright green brew with light aromatic grassy notes and a hint of freshly picked spring air. Occasionally, however, what fills your cup is more of a yellowish color, and from time to time even brown.
So which is it: brown or green?
This article will take you through why the colour of green tea changes, what that signifies for the teas you are drinking, and how brewing methods, processing, and different varieties all contribute to these greens (sometimes due to oxidation, which can also produce brownish colours).
Tea has always looked so plain to me. Take one example: I am amazed at how my Japanese green tea is so vivid, yet in contrast, while the other seems dull and muted by comparison.
Later, when you have a clearer picture, perhaps it will also bring out some charm and satisfaction out of each cup of tea you enjoy.
Why does green tea look different when you brew it?
The first thing to know is that the color of green tea comes from how the tea leaves are handled after harvesting. The reason is that it cannot be changed once that color change occurs on the factory floor and indeed still reflects real examples in practice today.
Researchers have found that processing methods for making green teas do not vary much from one area of China, Japan, or even England. Green tea comes from the leaves of a variety called Camellia sinensis.
Black tea and oolong were also made from the camellia sinensis plant. Different processing techniques lie behind each type of tea. In order to retain this fresh green color, the leaves are given a light steaming or quick pan-firing, which kills all potential oxidation instantly.
If left alone for a bit with air and sunlight, however, those same green leaves would rapidly turn brown. This is how black tea is made.
When you steep green tea, tiny compounds, like chlorophyll, amino acids, and catechins, move into the water. That’s why green tea can create many different shades of green depending on how long you brew, how hot the water is, and what tea type you’ve chosen.
Over-steep, and your cup of green tea can turn a brownish or orange hue that doesn’t taste nearly as nice as it should.
What makes Japanese green tea so bright?
If you’ve ever marvelled at the almost neon, bright green colour of Japanese green tea. That’s not your imagination. Japanese tea producers typically use steaming as their way to halt oxidation.
Steam locks in the chlorophyll tea leaves, thus keeping them greener in colour than Chinese green tea-which is commonly pan-fired and may develop a more yellowish hue.
Japanese green tea, especially matcha and sencha, often has a vivid, cloudy green brew. The tea leaves are either finely ground (in the case of matcha) or leaf steamed to keep their color rich green.
The result is a glass that is greener in hue and taste fresher than almost any other beverage: It tastes like fresh, tender spring vegetables. No wonder green tea is so treasured in Japan, it is green in appearance too as well as in the mouth.
Why does some green tea turn brown?
You may have brewed what you thought was quality green tea, only to watch it turn brown in color.
A green tea brown brew often comes from either over-steeping, using water that’s too hot, or tea leaves that have partially oxidized during processing. Even quality tea can turn brown if brewed carelessly.
Another reason is that some teas, like hojicha, are deliberately roasted. The roast turns the leaves brown, which naturally creates a brown brew with a toasty, nutty aroma.
This doesn’t mean the tea is poor; it’s simply a different tea type. Understanding why your tea turns brown helps you appreciate whether it’s a sign of over-brewing or simply the style of tea you’ve chosen.
How does matcha differ in tea color?
By whisking, not steeping, you end up with matcha.
The tea is powdered, which means that you consume it whole leaf. Thus, the tea’s color is a bright green, made even more so by the particles of leaf juice.
When you shade the tea plants before harvest, the result is a lively yellow tint from all that chlorophyll derived not just in but through them!
You can blend matcha to make the resulting cup smooth and frothy, with a creamy texture that no brewed tea, even top-quality green teas, can rival.
Moreover, it is traditional in the Japanese tea ceremony to judge a good matcha green not only by its taste but also by its appearance.
If the powder is lumpy or left unmixed in a cup, clearly, poor quality or carelessness can show in subtle ways as well as blatantly, and no one wants that.
What role does sencha play in green tea colors?
Sencha is a main traditional type of Japanese tea, and depending on how it is made, it can appear in varying shades of green.
When brewed, a normal sencha turns out light green, like olive oil and creamy milk, sometimes even more white than green.
A higher-grade gyokuro, a shade-grown tea similar to matcha, produces a dark green, sweet flavor considered one of the best green teas.
Because sencha is steamed, it retains more chlorophyll in the tea leaves, making it greener than many Chinese green teas.
Sencha and matcha together represent the bright side of Japanese tea, where this kind of tea brew is more green-looking than teabroth brown or hojicha orange feuilege.
What about hojicha and other roasted teas?
Tea can be oxidized in two ways: when roasted, chlorophyll breaks down. This makes the leaves brown, creating a light brown to reddish-brown color in the cup.
The taste is toasty smooth and contains less caffeine, so Hojicha is a warm way to go for an evening drink.
But if hojicha technically belongs to the category of green tea because it is made from a tea plant that produces green tea, then its roasted leaves appear brown, and the tea’s liquid also turns brown.
Not every kind of green tea is really green; that’s the way it goes. There are brown brews out there, too. Some green teas are intentionally prepared for a different brewing method.
Do Chinese green teas look different?
Compared with Japanese green tea, Chinese green tea is not steamed but is pan-fired instead. The outcome is that it has the look of the withers (like a dragon well) being much closer.
Thus, the color of green tea is utterly different; Japanese tea is often a bright green because it is steamed.
Chinese teas often have lighter or more yellowish hues than this because they have been pan-fired. Neither is better, but the tea leaves leave behind deposits of both color and taste.
How does oxidation affect the color of tea?
When chlorophyll and the other compounds that keep green leaves green become oxidized in a process called oxidation, the tea leaf turns black.
When tea leaves are fully oxidized they turn black or brown. The heating of tea leaves in processing is the key difference between green tea Black Tea Red Oolong Yellow Bundi.
Green tea will go brown from proper storage, or even naturally oxidize. That is why it is essential to store your tea well apart from light, air, and water. If left out even good-quality green tea will turn brown and lose its fresh taste.
How do brewing methods change the color of the tea brew?
The method of making the tea is an important factor that determines the final color of green tea. Water that is too hot will merely burn the leaves, producing a muddied, brownish tea.
In contrast, over-brewing with steam releases too many tannins, turning the water brown and making it bitter because of how it has been processed.
A shorter minute steep with cooler water typically yields a light green brew full of sweetness from the delicate buds.
The tea brewed in your cup is the end product of the release of chlorophyll, amino acids, and tannins from green tea leaves.
To achieve your desired hue or flavor, simply adjust the steeping time, reci-temperature and type of tea.
What do the different shades of green tea mean?
Green tea varies in shade, ranging from light green to dark green, even milky and golden, but this gives the drink a different feel.
A high mountain tea might be best suited to drinking from a porcelain cup with a light, sweet green tincture, while the same weight of juice from the yellow shade would appear as a basic green color in earthenware dishes.
A vivid green cup could mean fresher, steamed tea, as with Japanese sencha, but a somewhat yellowish color may suggest pan-fired Chinese green tea.
A dark brown drink will likely be one of two things: baked leaves or overleafage. Maybe both. Paying attention to the green tea’s hues softens its harshness.
Tea color is also related to the flavor. Alternatively, a yellow brew is flatter and more astringent. Seeing the color of green tea helps you understand its origin and momentum.
Which types of tea share similarities in color?
Black tea steeps to a reddish color, oolong tea to a yellowish-brown, and white tea is often pale yellow.
Yellow teas are rare (and expensive), but their color lies between that of green and black. Even teas such as hojicha demonstrate that a green tea can turn brown and still be very good.
Green tea and other typical tea colors come from the same plant species, camellia sinensis. Only during processing, steaming, pan-frying, oxidation, or roasting can a cup of tea differ between green and brown.
This is why a single cup of green tea could be anywhere from light green to deep brown, and why the tea expert discerns every shade at once.
