How Green Tea Processing Preserves Its Delicate Flavor and Aroma
Green tea is defined by what doesn't happen to it: oxidation is halted early, preserving the leaf's vibrant green colour, fresh aroma, and delicate flavour compounds. The result — when grown at altitude and processed carefully — is one of the most nuanced and health-supportive beverages available. Here's exactly how it's made.
How Green Tea Is Processed
- Plucking: Only the youngest leaves and buds are selected — typically the top two leaves and a bud. Hand-plucking at altitude, as practiced on Nepal Hills' farms in Ilam at 5,000–7,000 ft, ensures only the finest material enters production.
- Withering: Freshly picked leaves are spread to wither slightly. Unlike black tea, green tea's withering is brief and minimal.
-
Heat treatment (the critical step): Heat is applied quickly to halt enzymatic oxidation. Two methods are used:
- Pan-firing (Chinese/Nepali style) — leaves are tossed in a hot wok or pan. Produces slightly roasted, vegetal flavour with gentle sweetness.
- Steaming (Japanese style) — leaves are steamed briefly. Produces a brighter, grassier character.
- Rolling: Leaves are gently rolled to shape them and release aromatic compounds.
- Drying: Final drying locks in the leaf's character and reduces moisture to storage-stable levels.
Green Tea vs. Black Tea: The Core Difference
| Factor | Green Tea | Black Tea |
|---|---|---|
| Oxidation | Halted immediately (0%) | Full oxidation (100%) |
| Flavour | Fresh, vegetal, floral, light | Malty, bold, sometimes fruity |
| EGCG / catechins | High — preserved by minimal oxidation | Converted to theaflavins during oxidation |
Nepal Hills Green Teas
Nepal Hills produces two green teas from certified organic farmland in Ilam at 5,500 ft:
- Floral Green Tea — floral, light sweetness, no bitterness. Pan-fired. Brew at 75–85°C for 2–3 minutes.
- Organic Light Green Tea — smooth, light, low caffeine. The brand's lightest tea. Brew at 75–85°C for 2–3 minutes.
High altitude slows leaf growth, concentrating amino acids (especially L-theanine) and catechins. The result is green tea with natural sweetness and no bitterness.
How to Store Green Tea
- Airtight container away from light, heat, and moisture
- Away from strong-smelling foods — green tea absorbs odours easily
- Consume within 12 months of harvest for optimal flavour

Frequently Asked Questions
Why does green tea sometimes taste bitter?
The two most common causes are water that is too hot and over-steeping. Brew at 75–85°C for 2–3 minutes — not boiling. High-altitude green teas like Nepal Hills Floral Green are naturally lower in tannins due to slower leaf growth, making them more forgiving than lowland varieties.
What is the difference between steamed and pan-fired green tea?
Both halt oxidation using heat. Steaming (Japanese style) produces a bright, grassy, vegetal character. Pan-firing (Chinese and Nepali style) produces a slightly more rounded character with mild roasted notes and less grassiness. Nepal Hills' green teas are pan-fired, giving them a naturally floral sweetness.
Is green tea caffeinated?
Yes, but with significantly less caffeine than black tea or coffee — typically 20–40mg per cup vs. 40–70mg for black tea. Green tea also contains L-theanine, which produces calm focus rather than jitteriness.
Can I re-steep green tea leaves?
Yes — high-quality loose leaf green tea can be re-steeped 2–3 times. For subsequent steeps, use slightly hotter water and a longer steep time. Whole-leaf teas like Nepal Hills Floral Green hold up well to multiple steeps.
