Frequently Asked Questions
What is a coffee brew ratio?
A coffee brew ratio is the relationship between the amount of coffee grounds and water used in brewing, typically expressed as 1:X (e.g., 1:16). This means for every 1 gram of coffee, you use X grams of water.
What is the best brew ratio for coffee?
The ideal brew ratio depends on your preference. A balanced ratio of 1:15 to 1:17 works well for most pour over and drip coffee. Stronger ratios (1:12 to 1:15) are common for concentrated brews, while milder ratios (1:17 to 1:20) produce lighter coffee.
How do I calculate water amount from brew ratio?
Multiply your coffee dose by the ratio number. For example, with 20g of coffee and a 1:16 ratio, you need 20 × 16 = 320g (or ml) of water.
What brew ratio should I use for pour over coffee?
For pour over coffee, a ratio between 1:15 and 1:17 is recommended. A 1:16 ratio is a great starting point that produces balanced, flavorful coffee.
Does brew ratio affect coffee strength?
Yes, brew ratio is one of the primary factors affecting coffee strength. Lower ratios produce stronger coffee, while higher ratios produce milder, lighter coffee.
