1. What is Coffee Brew Ratio?

The coffee brew ratio is the relationship between the amount of coffee used and the amount of water used in brewing. It's typically expressed as a ratio like 1:16, meaning 1 gram of coffee to 16 grams of water.

2. How Does the Calculator Work?

The calculator uses the brew ratio formula:

Where:

• \( Water \) — Amount of water in grams
• \( Ratio \) — Brew ratio (e.g., 16 for 1:16 ratio)

Explanation: The formula calculates the amount of coffee needed based on your desired water volume and brew ratio.

3. Importance of Brew Ratio

Details: The brew ratio is fundamental to coffee extraction. It affects strength, flavor balance, and extraction yield. Different ratios work better for different brew methods and coffee types.

4. Using the Calculator

Tips: Enter water amount in grams and your desired brew ratio. Common ratios range from 1:15 to 1:18 for pour-over, 1:12 to 1:15 for espresso.

5. Frequently Asked Questions (FAQ)

Q1: What's a good starting ratio for pour-over?
A: A 1:16 ratio (1g coffee to 16g water) is a good starting point for most pour-over methods.

Q2: How does ratio affect coffee strength?
A: Lower ratios (e.g., 1:12) produce stronger coffee, while higher ratios (e.g., 1:18) produce lighter coffee.

Q3: Should I measure by weight or volume?
A: Always measure by weight (grams) for consistency, as coffee density varies and volume measurements are less accurate.

Q4: Does the ratio change for different brew methods?
A: Yes, espresso typically uses 1:2-1:3, Aeropress 1:12-1:16, French press 1:15-1:17.

Q5: How important is water temperature?
A: While ratio is crucial, water temperature (195-205°F) also significantly impacts extraction.
