How Is Tea Made?

Tea, one of the world's most beloved beverages, is a product of craftsmanship and centuries-old traditions. While it may seem like magic in a teacup, the process of turning tea leaves into that soothing, aromatic infusion is a fascinating journey that involves careful cultivation, harvesting, withering, oxidation, and more. In this blog post, we'll explore the essential steps that transform tea leaves into the delightful brew we know and love. Keep in mind that the order of these steps (and whether they're involved at all) does vary between the 6 main tea types, and the steps do not necessarily apply to herbal teas. Join me as we embark on a journey through the basics of how tea is made.

Step 1: Cultivation and Harvesting

The journey of tea begins in the tea gardens, where the tea plant, Camellia sinensis, is lovingly nurtured. The quality of tea depends on factors like soil, climate, altitude, and terroir—the unique environmental conditions of the region.

Cultivation

Tea plants thrive in well-drained soil and temperate climates. They are often grown on slopes to ensure good drainage and sunlight. In some regions, tea plants are meticulously pruned to encourage new growth and maintain manageable bush size.

Harvesting

The timing of tea leaf harvesting is crucial. Tea is typically harvested in flushes, which are distinct growth periods. The first flush, often in spring, yields delicate, young leaves prized for their freshness. Subsequent flushes produce leaves with different flavors and characteristics. Some teas, like black tea, may have several flushes throughout the year.

Step 2: Withering

After plucking, tea leaves undergo withering, a process that reduces their moisture content and initiates the transformation. The leaves are spread out on trays or mats, allowing them to wilt and lose some of their water content. Withering can last anywhere from a few hours to a full day, depending on the type of tea being produced.

Withering is essential for preparing the leaves for the next stage—rolling. The moisture loss makes the leaves pliable, preventing them from breaking during rolling.

Step 3: Rolling

Rolling is where the magic of shaping tea leaves begins. Traditionally, rolling was done by hand, but today, machines are often used for efficiency. The process involves gently rolling or twisting the leaves to release their natural juices and oils. This action starts to break down the leaf cell walls, facilitating oxidation—a crucial step for many tea types.

The rolling process varies depending on the type of tea being produced. For example, green tea leaves are rolled to maintain their green color and prevent excessive oxidation, while black tea leaves are rolled to encourage oxidation, leading to darker leaves and a deeper flavor profile.

Step 4: Oxidation

Oxidation is the heart of the tea-making process and is responsible for the vast flavor differences among tea types. It's a chemical reaction that occurs when the rolled leaves are exposed to oxygen. During oxidation, enzymes in the leaves interact with the oxygen, changing the color, aroma, and flavor of the tea.

Green Tea: For green tea, oxidation is minimized or halted by quickly heating the leaves after rolling. This step preserves the green color and produces a fresh, grassy flavor.

Black Tea: In contrast, black tea undergoes full oxidation. The leaves are allowed to fully interact with oxygen, resulting in dark, robust flavors, and the characteristic black color.

Oolong Tea: Oolong tea falls somewhere in between green and black tea, undergoing partial oxidation. The degree of oxidation varies, resulting in a wide range of flavors, from floral and fruity to toasty and earthy.

Step 5: Firing or Drying

After the desired level of oxidation is achieved, it's time to fire or dry the tea leaves. This step serves multiple purposes: halting oxidation, reducing moisture, and enhancing flavor. By applying heat to the leaves, oxidation is stopped, preserving the desired flavor and aroma characteristics. Drying reduces the moisture content of the leaves, preventing spoilage and extending shelf life. The firing process can enhance the flavors of the tea, adding depth and complexity.

Firing methods can vary, from pan-frying in a wok for some green teas to drying in large ovens for others.

Step 6: Sorting and Grading

After firing, the tea leaves are carefully sorted and graded based on their size, shape, and quality. This step ensures that each batch of tea meets the desired standards and allows for consistency in flavor and appearance.

Tea grading often includes designations like whole leaf, broken leaf, fannings, or dust. Whole leaf teas are considered of higher quality, while smaller grades are often used in tea bags.

Step 7: Packaging and Distribution

Once the tea has been sorted and graded, it's packaged into various forms, including loose leaf, tea bags, or compressed shapes like bricks or cakes. The packaging can affect the tea's shelf life and preservation of flavor.

Tea is then distributed to markets worldwide, making its way to the shelves of grocery stores, specialty tea shops, and online retailers. That's it! It's all ready for you to brew and enjoy.

The journey from leaf to cup is a testament to the artistry and tradition that goes into making tea. Each step, from cultivation to packaging, plays a crucial role in shaping the flavors and characteristics of the final product. The process the tea leaf goes through also affects the retention of potential health benefits that Camellia sinensis is known for. So, the next time you savor a cup of tea, remember the centuries of craftsmanship and care that went into every leaf. It's a journey worth toasting with each delightful sip. Cheers!
