Coffee Wiki

AeroPress

A versatile pressure-assisted immersion brewer with an exceptionally wide parameter range, favoured for travel, experimentation, and forgiving daily use.

Chemex

A pour-over brewer using an exceptionally thick bonded paper filter that produces one of the cleanest, most sediment-free cups in manual coffee brewing.

Espresso

A concentrated, pressure-driven extraction method that produces a small, intense shot with significant emulsified oils, dissolved solids, and crema.

French Press

A full-immersion brewer using a metal mesh filter, producing a heavy-bodied, oil-rich cup with more texture than any paper-filter method.

Hario V60

A cone-shaped pour-over brewer that rewards technique and highlights clarity, brightness, and origin character in the cup.

Brazil

The world's largest coffee producer, known for low-acid, nutty, and chocolatey naturals that form the backbone of most espresso blends globally.

Colombia

A year-round producing origin with exceptional geographic diversity, delivering consistently balanced, approachable cups that introduce the world to specialty coffee.

Ethiopia

The genetic and cultural birthplace of Coffea arabica, producing some of the world's most complex and florally distinctive cups from ancient heirloom varieties.

Kenya

One of the world's most distinctive coffee origins, producing intensely complex cups defined by blackcurrant, tomato, and citrus from unique SL varieties and double-fermentation processing.

Anaerobic Fermentation

A controlled oxygen-free fermentation process that produces intensely complex, often polarising flavour profiles through CO2-pressurised sealed tank fermentation.

Honey Process

A partial-mucilage processing method that sits between washed and natural, producing a sweet, medium-bodied cup with complexity that avoids the fermentation risk of full naturals.

Natural Process

The oldest coffee processing method, drying whole cherries with fruit intact to produce intensely fruity, wine-like, full-bodied cups with high fermentation complexity.

Washed Process

The dominant specialty coffee processing method, removing all fruit before drying to produce a clean, terroir-forward cup that expresses origin character with exceptional clarity.

Extraction Science

The fundamental science of how water dissolves compounds from ground coffee, what those compounds are, and how to use extraction yield and TDS to diagnose and improve any brew.

Grind Guide

A comprehensive guide to grind size, burr geometry, particle distribution, and how to dial in by taste for any brew method.
