1. What Is Coffee Extraction Yield?

Extraction Yield (EY) measures the percentage of coffee solids extracted from the ground coffee into the beverage. It's a key metric in coffee brewing that helps determine the quality and strength of the final cup.

2. How Does The Calculator Work?

The calculator uses the extraction yield equation:

Where:

• \( Beverage \) — Weight of the final brewed coffee (grams)
• \( TDS \) — Total Dissolved Solids percentage (%)
• \( Dose \) — Weight of the ground coffee used (grams)

Explanation: This equation calculates what percentage of the original coffee grounds has been dissolved into the final beverage.

3. Importance Of Extraction Yield

Details: Optimal extraction yield (typically 18-22%) ensures balanced flavor extraction. Under-extraction results in sour, weak coffee while over-extraction leads to bitter, harsh flavors.

4. Using The Calculator

Tips: Enter beverage weight in grams, TDS percentage, and coffee dose in grams. Use precise measurements from a coffee refractometer for TDS and a digital scale for weights.

5. Frequently Asked Questions (FAQ)

Q1: What is the ideal extraction yield range?
A: Generally 18-22% is considered optimal, though this can vary based on coffee roast and personal preference.

Q2: How do I measure TDS accurately?
A: Use a coffee refractometer specifically calibrated for coffee brewing to get precise TDS measurements.

Q3: Why is extraction yield important for coffee quality?
A: It helps ensure consistent brewing results and allows you to adjust variables to achieve your desired flavor profile.

Q4: Does this work for all brewing methods?
A: Yes, the extraction yield calculation applies to espresso, filter, French press, and other brewing methods.

Q5: What affects extraction yield?
A: Grind size, water temperature, brew time, and agitation all significantly impact extraction yield.
