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 compounds. Specialty standards aim to extract 18% to 22% of this mass. Under-extraction causes sourness, while over-extraction introduces harsh bitterness.
Total Dissolved Solids measure cup strength. Filter coffee typically sits at 1.15%–1.45% TDS (98.5%+ pure water), whereas Espresso reaches 8%–12% TDS. Brew ratio directly controls this intensity.
Water always follows the path of least resistance. Pairing precise ratios with calibrated grind sizes ensures even contact time, preventing channeling for a clean, sweet extraction.
Intense gravity decoction. Formulated to extract heavy solubles and chicory that pair seamlessly with hot, velvety frothed milk.
High pressure, short contact time. Produces a concentrated, viscous shot topped with golden crema and rich chocolate-nut notes.
Gravity-fed filter extraction. Delivers high flavor clarity, highlighting vibrant floral, fruity, and subtle acidic notes in single origins.
Full immersion brewing. Allows coffee grounds to steep evenly, creating a sweet, rounded body with smooth, low acidity.
