Hand Drip Brew & Yield Calculator | Perfect Your Pour-Over Recipe

This online tool helps you precisely calculate the key variables for your hand-drip coffee. By inputting your coffee bean weight and desired ratio, it instantly provides the target water amount, predicts the final beverage yield, and generates a simple 3-step pouring guide for consistent results.

💡 Tool Overview

• Instant Recipe Generation: Automatically calculates the total water needed for your brew based on the coffee dose and brew ratio.
• Predictive Yield Calculation: Estimates the final amount of coffee in your cup by accounting for the water absorbed by the grounds.
• Guided Pouring Steps: Provides a clear, 3-step pouring plan (Bloom, Main Pour, Final Pour) to help you achieve a balanced extraction every time.
• Advanced Customization: Allows you to fine-tune the "Absorption Ratio" to match the specific characteristics of your coffee beans (e.g., roast level, density) for maximum accuracy.

🧐 Frequently Asked Questions

Q. What is a good starting point for the brew ratio?

A. A widely accepted starting point for pour-over coffee is between 1:15 and 1:17 (1 gram of coffee to 15-17 grams of water). You can adjust from there based on taste. A higher ratio (e.g., 1:17) generally results in a lighter-bodied cup, while a lower ratio (e.g., 1:15) produces a more concentrated brew.

Q. What is the "Absorption Ratio" and why is it important?

A. The Absorption Ratio (or coefficient) represents how much water the coffee grounds retain after brewing. As a rule of thumb, coffee grounds absorb approximately twice their own weight in water, which corresponds to an absorption ratio of 2.0. This value can change depending on the roast level (lighter roasts tend to absorb more), grind size, and freshness. Adjusting this setting gives you a more accurate prediction of your final liquid yield.

📚 Fun Facts: Yield vs. Extraction

In the world of coffee, "yield" and "extraction" are two distinct but related concepts. This calculator helps you control the yield, which is simply the total weight or volume of the final brewed coffee in your cup.

Extraction, on the other hand, refers to the percentage of soluble solids that have been dissolved from the coffee grounds into the water. While this tool doesn't measure extraction directly, controlling your yield is a critical first step to achieving a consistent and desirable extraction. By repeatedly hitting your target yield, you create a stable foundation to then adjust other variables, like grind size or water temperature, to perfect the taste of your coffee.
