The Science of Extraction

Understanding the variables that shape every cup

Interactive Flavor Profile

Adjust the parameters below to see how temperature, grind size, and steeping time influence the balance between bitterness and acidity in your brew.

Temperature Dynamics

Water temperature is the primary driver of extraction efficiency. Higher temperatures accelerate the release of compounds, while lower temperatures allow for more selective extraction of delicate flavors.

80-85°C

Gentle extraction preserves delicate aromatic compounds. Ideal for green teas and light roasts.

85-90°C

Balanced extraction suitable for most varieties. Provides a harmonious release of compounds.

90-95°C

Intense extraction for robust profiles. Best for dark roasts and full-bodied teas.

Particle Size Impact

The surface area exposed to water determines how quickly compounds are extracted. Finer grinds increase surface area, leading to faster extraction but requiring shorter contact times.

Coarse grind particles

Coarse Grind

Large particles require longer steeping times. Produces cleaner, less intense extractions.

Medium grind particles

Medium Grind

Versatile particle size suitable for various brewing methods and timeframes.

Fine grind particles

Fine Grind

Maximum surface area enables rapid extraction. Requires precise timing to avoid over-extraction.

Time Variables

Steeping duration affects which compounds are released and in what proportions. Different compounds extract at different rates, creating a dynamic flavor profile that evolves over time.

Short steeping time

1-2 Minutes

Initial extraction phase. Releases bright, acidic compounds with minimal bitterness.

Medium steeping time

3-4 Minutes

Balanced extraction period. Achieves harmony between acidity and body.

Extended steeping time

4-5 Minutes

Extended extraction. Develops deeper body and increased bitterness.

Compound Release Patterns

Understanding the sequence of compound extraction helps predict flavor development. Caffeine and acids extract quickly, while tannins and complex molecules require more time.

Early Stage Extraction

The first minute releases volatile aromatics, caffeine, and bright acids. This phase contributes to the initial flavor impression and perceived freshness.

Mid-Stage Development

Between two and four minutes, body-building compounds emerge. The balance shifts toward complexity and depth.

Late Stage Extraction

Extended steeping releases tannins and bitter compounds. These contribute to structure but can overwhelm delicate flavors if over-extracted.
