How Tea Is Processed, From Leaf to Cup
Six tea types, one plant. The processing steps are what separate them — here is each one in order.
Key takeaways
- Withering, bruising, oxidation, fixing, rolling and drying — in different combinations.
- 'Fixing' with heat is what stops oxidation and creates green tea.
- Nothing is added to real tea; flavor comes entirely from processing choices.
The six steps
Not every tea uses every step, and the order and duration vary by region and producer.
- Withering — the leaf loses moisture and becomes pliable
- Bruising or rolling — cell walls break, releasing enzymes
- Oxidation — enzymes react with air, darkening the leaf
- Fixing — heat (steaming or pan-firing) halts oxidation
- Shaping and drying — final form and moisture level
- Aging or fermentation — only for dark teas like pu-erh

Single-origin loose-leaf tea, 3.5 oz
A 100 g pouch of single-origin leaf with harvest and region on the label.
Why we recommend it: One good tea, drunk often, teaches more than twelve mystery pouches.
Variable-temperature gooseneck kettle
Electric gooseneck kettle with presets from 160°F to boiling and a hold-temp setting.
Why we recommend it: Green and white tea scorch above 180°F — presets take the guesswork out of every steep.
How each type is made
White tea: wither, dry. Green tea: fix immediately, roll, dry. Oolong: wither, bruise repeatedly, partially oxidize, fix, roll, sometimes roast. Black tea: wither, roll, fully oxidize, dry. Dark tea: as green tea, then pile-ferment and press.

Sencha, gyokuro, dragon well and gunpowder in single-session pouches.
Why we recommend it: The cheapest way to find out which green tea style you actually like.
Why this matters when you buy
Once you know a tea's processing, its brewing follows. Fully oxidized and roasted teas take boiling water; unoxidized and delicate ones do not. You no longer need to memorize charts per tea name.
Recommended products to get started

Why we recommend it: Keeps tea hot, stays cool to hold, and you can judge strength by color.
Porcelain teacup set, 6 pieces
Thin-walled 4 oz porcelain cups for tasting and gongfu sessions.
Why we recommend it: Small cups cool fast so you can taste each short steep at its peak.
Frequently asked questions
- Is 'fermented tea' the same as oxidized tea?
- No, though the words are used loosely. Oxidation is enzymatic; true fermentation involves microbes and applies to pu-erh and other dark teas.
- What is CTC?
- Crush, Tear, Curl — a machine process that produces the small uniform granules used in tea bags and masala chai. Strong and fast, but no re-steeps.
