Level 01 • The Basics

Sensory Lexicon

Speak the language of coffee. A visual dictionary.

🍋

Acidity

Flip

Sparkle, not sourness. Think lemon zest or green apple.

🥛

Body

Flip

The weight on your tongue. Like milk vs water.

🍯

Sweetness

Flip

Sugary qualities derived from ripe cherries and roasting.

🍫

Bitterness

Flip

Essential for balance, like dark chocolate or tonic water.

🏁

Finish

Flip

The aftertaste that lingers. Good coffee stays with you.

👃

Aroma

Flip

The smell of brewed coffee (wet fragrance).

01
Exocarp

Outer Skin

The protective outer skin containing anthocyanins. Color indicates maturity (Green → Red).

cellular
02
Mesocarp

Pulp

Sugar-rich mucilage driving fermentation. High Brix content (15-25°).

flesh
03
Parenchyma

Mucilage

Sticky hydro-gel layer. Removed via fermentation or mechanical demucilaging.

gel
04
Endocarp

Parchment

Tough cellulose hull protecting the seed during drying (10-12% moisture).

fiber
05
Spermoderm

Silver Skin

Paper-thin membrane adhering to the seed. Becomes "chaff" during roasting.

Endosperm

Green Bean

The seed containing lipids, acids, and caffeine. The source of all flavor.

The "Mud" Problem

Blade grinders shatter beans. You get dust (fines) that over-extracts instantly and chunks (boulders) that never extract fully. The result is a cup that is confusingly bitter AND sour.

Level 03 • The Science

Science Archives

Advanced theory. TDS, Chemistry, and Physics.

DOC_01

TDS & Yield

Total Dissolved Solids

Yield % = (Bev Wt x TDS %) / Dose

Strength vs Extraction. The math behind the perfect cup.

DOC_02

Water Chemistry

Buffer & Hardness

Mg²⁺ + Ca²⁺ + HCO₃⁻

Why your water matters more than your beans. Mg vs HCO3.

DOC_03

Maillard Reaction

Browning Phase

Amino Acid + Sugar → Melanoidins

The chemical reaction between amino acids and sugars that gives roasted coffee its flavor.

The Resting Curve

Why fresh isn't always best. The relationship between CO2 and Flavor.

Patience pays off.

Freshly roasted beans are full of CO2. Brewing too early leads to sour, gassy cups. Most specialty coffee peaks 10-14 days after roast.

Day 1-3: Too Fresh

High CO2 prevents water contact. Sour & metallic taste.

Day 10-14: Peak Flavor

CO2 stabilized. Flavor notes are distinct and sweet.

Day 30+: Oxidation

Volatiles lost. Cup becomes flat and woody.
