Understanding Coffee Brewing Ratios
The secret to a café-quality cup of coffee isn't just the beans; it's the math. The coffee-to-water ratio determines the strength (TDS) and extraction level of your brew. Using a coffee ratio calculator ensures consistency every morning.
What is the Golden Ratio?
The Specialty Coffee Association (SCA) suggests a "Golden Ratio" of 1:18 (1 gram of coffee for every 18 grams of water). However, most enthusiasts prefer a tighter ratio of 1:15 to 1:17 for a more flavorful, full-bodied experience.
- 1:12 (Bold): Ideal for French Press or those who like a heavy mouthfeel.
- 1:15 (Balanced): Great for Hario V60 and most pour-over methods.
- 1:17 (Light/Tea-like): Perfect for Chemex to highlight bright, floral notes.
