In specialty coffee, water is not just a medium—it is the solvent. The ratio between coffee and water dictates strength, extraction yield, and sensory balance.
A roasted coffee bean contains roughly 30% water-soluble material. The SCA (Specialty Coffee Association) golden standard dictates extracting between **18% to 22%** of this weight. Under-extraction yields sourness; over-extraction brings dry bitterness.
Total Dissolved Solids measures concentration. Filter coffee typically sits at **1.15% - 1.45%** TDS (meaning 98.5%+ is pure water). Espresso reaches **8% - 12%** TDS. The ratio determines where your cup falls on this spectrum.
Water will always seek the path of least resistance. Using correct ratios alongside calibrated grind sizes ensures uniform contact time, avoiding channeling and securing a sweet, clean extraction.
Intense gravity decoction. Designed to extract heavy solubles (with chicory) that pair seamlessly with rich, frothy frothed milk.
High pressure, short contact time. Yields a concentrated, viscous shot topped with crema. Highlighted by chocolatey and nutty profiles.
Gravity-fed filter extraction. Provides high flavor clarity and highlights complex floral, fruity, and acidic notes in single origins.
Immersion brewing. Allows coffee grounds to brew fully submerged, generating a sweet, well-rounded body with lower relative acidity.
