The Alchemy of Tea How: Processing Transforms Leaves into Magical Brews

Some people like their “teas” like they like their bodies – in a bag, under water…

But all snarky humor aside, what’s commonly referred to as “tea” comes from only a single plant, (herbal ‘teas’ aren’t technically ‘tea’; they’re infusions or tisanes).

All true teas spring from the leaves of the Camellia sinensis plant. The pure sorcery is in the processing.  It’s through withering, bruising, oxidation, and firing that conjures wildly different potions: delicate whites, fresh greens, complex oolongs, and robust blacks. No two types undergo the same spell (though some lighter oolongs share steps with greens). At Witches Brew, we source the finest teas directly from trusted growers and artisans around the world so that we can deliver you authentic, high-quality potions ready to brew. No shortcuts, just real tea magic.

Curious how a single plant becomes the diverse brews in your cauldron?

Key Processing Steps and Tea Types

Basic steps for most teas:

Plucking → Fresh leaves harvested.

Withering → Leaves soften and lose moisture (starts natural oxidation).

Fixation (Kill-Green) → Heat stops oxidation by deactivating enzymes.

Rolling/Shaping → Bruises leaves to release juices and encourage oxidation.

Oxidation → Leaves exposed to air; level determines tea type.

Drying/Firing → Final heat to stabilize and preserve.

Here’s how processing varies:

1. GREEN TEA: Wicked Green (Minimal/No Oxidation: 0–10%) Leaves quickly heated right after plucking/withering to prevent oxidation.

Two main fixation methods: 

• Steamed (Japanese style) for 30–60 seconds to reserve a bright green color and fresh grassy/vegetal/umami flavors.

• Pan-fired (Chinese style): Leaves are tossed in hot woks which adds toasty, nutty notes, but slightly dulls the green color.

• Both are then rolled and dried.

2. White Tea: Witch’s Whisper (Very Light Oxidation: 5–20%) 

• Minimal processing: Withered (often indoors or sun) and dried naturally.

• Light bruising allows slight oxidation.

• Delicate, subtle sweet/floral flavors; fuzzy buds common (e.g., Silver Needle).

3. Oolong Tea: Dragon’s Charm Oolong (Partial Oxidation: 10–70%)

• Withered, bruised (often shaken in baskets), partially oxidized, then fired to stop.

• Rolling often heavy (ball-shaped or twisted).

• Wide range: Lighter oolongs floral/green; heavier roasted/nutty/fruity.

• Bruising and oxidation visible as leaf edges turn brown.

4. Black Tea: Naturally Noir (Full Oxidation: 80–100%)

• Heavily rolled to break cells, fully oxidized (leaves turn coppery/brown), then dried.

• Bold, malty, brisk flavors 

• In the west it’s called “black”; in China “red tea”, referring to brew color.

At Witches Brew, we respect the leaf. Whether you’re looking for a bright, grassy wake-up call or a dark, moody cup to stir your soul, we have the perfect potion waiting. Happy brewing!
