Tea and Life

Ever wondered how tea leaves transform into your favorite cup? It's all about tea processing. This journey turns fresh leaves from the tea plant (Camellia sinensis) into various tea types like black, green, oolong, or white. Let's explore the fascinating tea making process.

Essential Tea Processing Steps

1. Harvesting Tea

The journey begins when leaves are harvested from tea gardens. Skilled workers select the freshest parts — typically the top two leaves and a bud. The timing and method of harvesting significantly impact the final flavour profile.

2. Withering Process

After collection, leaves undergo withering. This crucial step reduces water content, making leaves pliable for further processing.

3. Rolling

Next, leaves are rolled either by hand or machine using the orthodox method, or by machine using the CTC method (Crush, Tear, Curl). Rolling breaks the cell walls of the leaves, releasing enzymes that initiate oxidation.

4. Oxidation Levels

This step creates the most significant differences between tea varieties: black tea undergoes complete oxidation; oolong undergoes partial oxidation; green and white teas have minimal oxidation.

5. Drying Process

Finally, the drying process halts oxidation and removes moisture, stabilizing the tea for storage and preserving its flavour and aroma.

Different Tea Types and Their Processing

Black Tea: Fully oxidized. Rich, bold flavours ranging from malt and cocoa to fruit depending on estate and altitude.

Green Tea: Oxidation minimized through steaming or pan-firing, preserving green colour and fresh, grassy taste.

Oolong Tea: Partially oxidized — anywhere from floral and light to rich and roasted depending on oxidation level.

White Tea: Least processed — just withering and drying. Delicate flavours and high intact polyphenols.

Taste the Processing Difference: Nepal Hills Single-Origin Teas

Nepal Hills Tea sources directly from high-altitude estates in Ilam and Taplejung using the orthodox method. Their range lets you taste exactly how processing transforms the same plant into different cups:

• Floral White Tea — minimal processing; withering and drying. Most delicate flavour, very low caffeine.
• Floral Green Tea — oxidation stopped early. Fresh, floral character preserved.
• Floral Oolong Tea — partial oxidation. Complex and floral with smooth finish.
• Muscatel Black Tea — full oxidation. Honey-grape muscatel character from Ilam's high-altitude estates.

The Tea Sampler Kit includes teas across all these styles — the most direct way to experience how processing transforms the same species into four completely different beverages.

Frequently Asked Questions

What is the difference between orthodox and CTC tea processing?
Orthodox processing rolls the leaves whole, preserving leaf structure and allowing slower, more nuanced extraction. CTC mechanically breaks the leaf into small uniform pieces, producing stronger, faster-brewing tea suited for tea bags. Orthodox teas are generally considered higher quality. Nepal Hills teas use the orthodox method.

How does oxidation affect tea flavor?
Oxidation transforms the leaf's chemical composition. Unoxidized teas (green, white) retain fresh, grassy, floral notes. Partially oxidized teas (oolong) develop complex fruity or roasted characteristics. Fully oxidized teas (black) develop deep malt, fruit, and chocolate notes.

Why does white tea taste so different from black tea if they come from the same plant?
Processing. White tea undergoes almost no processing — it's harvested, withered, and dried. Black tea is fully oxidized: enzymatic reactions transform the same starting compounds into entirely different molecules that produce deep colour, malt flavour, and characteristic astringency.
