Key ideas in Brewing the Perfect Cup
- Coffee beans vary in density based on roast level
- The 1:16 or 1:17 ratio is the industry standard for balance
- Volume measurements like spoons don't account for air gaps between beans
- Ratios are expressed as coffee weight to water weight
- Why weight is superior to volume for consistency
- Recall of the standard Golden Ratio
- Increasing the amount of coffee relative to water increases body/strength
- A lower ratio (e.g., 1:15) creates a more concentrated cup than a higher ratio (e.g., 1:18)
- Divide total water weight by the ratio number to find coffee dose
- 340 divided by 17 equals 20
- Lower ratios result in higher TDS (Total Dissolved Solids)
- Higher ratios dilute the flavor profile
- Calculating coffee dose for a specific output
- The Golden Ratio is a starting point, not a law
- Personal preference for 'strength' justifies moving to a 1:15 or 1:14 ratio
- Adjusting ratio to fix 'thin' or watery coffee
