Introduction
How to measure coffee to water ratio, deciphering coffee brew ratios, often termed coffee-to-water ratios, can be perplexing, leaving many to speculate on the ideal ratio for their morning cup. This guide aims to demystify the concept, explaining a 1:17 brew ratio, its execution, and customization to suit your palate. Additionally, we’ll explore espresso brew ratios, which differ from non-pressurized methods, and briefly delve into espresso-to-milk ratios for those aspiring to perfect traditional milk-based espresso beverages.
How to measure coffee to water ratio proportion for your brew
Coffee-to-water ratios, or brewing ratios, represent the proportion of coffee grounds to water used in brewing. For instance, 20 grams of coffee to 300 grams of water constitutes a 1:15 ratio.
20/300 = 1/15
The Specialty Coffee Association endorses a 1:18 ratio as the Golden Cup Standard for various brewing methods, such as pour-over, French Press, Chemex, and Autodrip. However, this standard doesn’t apply to pressurized brewing methods like espresso, which have significantly different recommended ratios.
Espresso Brew Ratios Defined
How to measure coffee to water ratio and Espresso brew ratio are distinct from typical drip or immersion brew ratios. For example, a double espresso adheres to a 1:2 ratio, aiming for 2 grams of espresso per gram of coffee in the portafilter. A standard double espresso recipe might use 19 grams of coffee to produce 38 grams of espresso within 30–35 seconds.
Espresso ratios range from 1:1 to 1:4, each with unique characteristics:
- Ristretto: A concentrated shot with a ratio between 1:1 and 1:1.5, known for its bold, rich flavor.
- Normale: A standard shot with a ratio between 1:2 and 1:3, offering a clearer espresso with a higher extraction percentage.
- Lungo: A larger shot with a ratio between 1:3 and 1:4, favored for its clarity, particularly with light-roasted coffees and complex single origins.
The Golden Brew Ratio
The Golden Cup Standard suggests a ratio of 1:17 to 1:18, ideal for those who appreciate a clear, light roast or single-origin coffee. Although some may find this ratio mild, it serves as a solid starting point on measuring coffee to water ratio, from there allowing for incremental adjustments to strengthen the brew.
Additional Factors Influencing Coffee Taste Beyond brew ratios, several factors affect coffee flavor:
- Time: The duration of brewing influences extraction, with deviations from the ideal time resulting in under- or over-extraction.
- Grind Size: The coarseness of the grind affects brewing speed and extraction, with finer grinds slowing down the process.
- Temperature: Often overlooked, temperature plays a crucial role in brewing quality, affecting acidity and bitterness.
- Coffee Processing and Roast Level: The coffee’s processing method and roast level significantly impact the final taste.
- Water: As the primary component of your brew, the quality of water used is paramount.
Enjoy your journey to the perfect cup of coffee, where precision meets personal preference.
