How Tea Leaves Are Refined

Tea leaves are refined through a series of steps. Each step determines the quality of the tea, from its taste to its strength and color.

First, the leaves are dried to reduce their moisture content to 60%-70%. Then they are rolled by machine, which breaks them up and exposes the chemical components to oxygen, allowing for the oxidation process to start.

Tea leaves are harvested a number of times throughout the year. The first harvest, known as a first flush, occurs in early spring. The plant is then able to grow more and develop a richer flavour.

The second harvest takes place in June or July. These are considered the best quality leaves and are therefore used for high-end teas.

The third and final harvest, also known as a fall harvest, takes place in mid October or November. The leaves are harvested to help the plant replenish nutrients. This is because the plants enter a dormant phase during winter.

Tea leaves undergo several stages of preparation and processing before they are ready to be used as tea. Each step is designed to bring out the best in a tea’s flavour, aroma and appearance.

The final stage, oxidation, is the most important. This involves breaking down some of the cells in the leaves, letting air interact with them and changing their chemical composition.

Once this is done, the resulting leaf will darken and change in colour depending on how much it has been oxidised. This level of oxidation determines what type of tea will be produced.

The next stage is rolling, where the damp tea leaves are encouraged into coils, balls, cones and other shapes. This is done either by hand or with a machine to create different types of teas.

How tea leaves are refined will affect their appearance, flavor and aroma. Traditionally, whole tea leaves are carefully rolled and shaped by hand or machine to form strips of tea that can be kneaded into curls, pellets or pearls.

Rolling breaks the cell walls of the leaves, allowing oxygen to interact with their essential oils and enzymes. It also helps release some of the sap and juice within the leaf, which is important in determining the final flavor of your cup of tea.

Next, the rolled leaves undergo a process of oxidation. Oxidation allows the leaves to break down chlorophyll and produce tannins, which change the color of the tea and its taste. The oxidation process takes place in a warm environment and can take several hours to complete.

Tea leaves undergo oxidation during processing, which contributes to their distinctive aroma and taste. Oxidation also produces compounds that contribute to tea’s color, strength and briskness.

This process of oxidation converts catechins (polyphenols) into theaflavins and thearubigins, which offer a variety of flavors and aromas in finished teas. It also produces the chlorophylls, pheophytins and pheophorbides that give dried leaves their black/brown color.

While oxidation is natural, the amount of oxidation that takes place during the processing of tea depends on the type of tea. Black teas are fully oxidized, while green and oolong teas are only partially oxidized.

Tea leaves must be dried in order to preserve their quality. Fresh leaves are easily spoiled due to their short shelf-life, which makes them unsuitable for trading or long-term storage.

Traditionally, two methods are used to dry tea: sun drying and charcoal firing. Both methods are weather dependent and can be done using basic tools in your kitchen.

Sun drying involves placing the leaves on a drying screen or hanging them from a drying rack and allowing them to dry in the sun. This method can take several hours and is not the quickest, but it is a very low-tech and traditional way to dry your tea.

When it comes to tea, there are a few basic categories that can make it easier to understand how a tea is processed and what it will taste like when brewed.

These categories include Black Tea, Green Tea, White Tea, Oolong Tea and Herbal Tea. Each has its own unique signature characteristics and processing methods.

Black tea is a type of tea that has been fully or mostly oxidized. This oxidation process is responsible for the dark color, flavor, and moderate amount of caffeine in black tea.

Black teas are classified into different categories depending on the processing method. These include:

Orthodox — This is the traditional way of processing black tea. It involves the whole leaf of the tea plant.

Non-Orthodox — This is a less laborious process that uses a machine to crush and tear leaves into small, irregular pieces of black tea.

These types of black teas tend to have more body and stronger, bolder flavors than orthodox black teas. They are also more affordable.

Common types are Zheng Shan Xiao Zhong, Yun Nan Dian Hong etc. It can be served with glass teapot.

Green tea is a type of tea made from the leaves and buds of the camellia sinensis plant. It is a lighter color and has a less astringent taste than black or oolong teas.

It is also lower in caffeine than black or oolong teas. Steeping green tea is typically done at a lower temperature than black or oolong teas, and it can be steeped for shorter periods of time.

The flavor of a tea will depend on where it is grown and how it was processed. It can be light and floral, grassy, astringent, nutty or sweet.

There are many different types of green teas, each with its own distinct flavor profile. The growing conditions, horticultural methods and production processing are important to the flavor of green tea.

Like green tea, green tea extract is a great source of antioxidants. These have been credited with a range of health benefits — from promoting heart, liver, and brain health to improving your skin and even reducing the risk of cancer.

What’s more, many studies have looked at the ability of green tea to aid weight loss. In fact, many weight loss products list it as a key ingredient.

White tea is a type of unfermented, uncured green tea that is minimally processed. It is produced from buds and young leaves of the tea plant that are harvested before they ripen, thereby avoiding some of the oxidation that is necessary for other types of teas.

It is believed that white tea originated in Fujian Province of China, the Chinese common types are Bai Hao Yin Zhen, Bai Mudan, Shou Mei etc. However, it is now cultivated in many countries worldwide including Japan, Nepal, India and Galle (Southern Sri Lanka).

The antioxidants in white tea are called polyphenols, which have been linked to a lower risk of Alzheimer’s and Parkinson’s diseases. They may also help fight inflammation and prevent proteins from clumping, which are both linked to these disorders. In addition, white tea has been shown to help reduce insulin resistance, a condition where the body doesn’t respond well to insulin, which is linked to heart disease and other health problems.

Oolong tea is one of the most unique categories of tea. It is not black or green, but falls somewhere in between and is often described as a partially oxidized tea (meaning it isn’t fully oxidized like black or green).

Oolong is known for its rich color, rich aroma and distinct flavor profile that can vary depending on how the tea master has manipulated its leaves. Some oolongs have deep chocolate notes, others are floral and buttery or savory.

Oolongs are classified into different styles based on the area of origin and how they were processed. This includes things like oxidation level, shape, and roast, like Tie Guan Yin, Wu Yi Yan Tea, Feng Huang Dan Cong etc.

There are many types of black teas, each with its own characteristics and flavors. Some of the best known varieties are Pu’er Tea from Yunnan Province, Liubao Tea from Guangxi Province and Anhua Dark Tea from Hunan Province.

The process of making dark tea is quite complex and involves several steps. First, the leaves are rolled and dried before they are placed in piles that are exposed to low temperatures and humidity. This process is called piling and was developed as a way to preserve the taste of dark tea under harsh conditions.

Another step in the production of dark tea is its processing, which usually takes place in a warehouse and is done to stop the oxidation process. This is done by reducing the amount of sunlight and watering the piles at regular intervals.

During this time, the tea is aged in a controlled environment and then sorted into grades based on size (whole leaf, brokens, fannings and dust). The best dark teas are graded as “orange pekoe” which can be distinguished from broken leaves and fannings by their coarse texture.

Other than its color and taste, dark tea is known for its health benefits. It is rich in antioxidants and polyphenols that can prevent the onset of chronic diseases.

In addition, dark tea contains a large amount of peptides and enzymes that can help regulate blood sugar levels. It also contains a lot of fiber that can aid digestion and reduce the absorption of carbohydrates.

The health benefits of dark tea have been extensively investigated and are thought to be due to its high concentration of antioxidants, polyphenols, and other compounds that help prevent the onset of diseases. Other studies have also found that it is a good source of vitamin C and potassium, and can boost immunity.

Herbal teas, also known as tisanes or infusions, are made by pouring hot water over plant parts such as flowers, fruits, seeds, leaves, and roots. Herbal teas do not come from the Camellia sinensis plant, which is the source of true tea (green, black, white and oolong).
