Frequently Asked Questions
What is the golden ratio for pour over coffee?
Specialty Coffee Association (SCA) standards recommend a 1:16 ratio (60g of coffee grounds per 1000g / 1 liter of water) for clean, balanced extraction.
Why is brewing water measured in grams?
Because 1 milliliter (ml) of water weighs exactly 1 gram, specialty baristas use digital gram scales for absolute recipe consistency.
