Frequently Asked Questions
What is the golden ratio for coffee?
The SCA (Specialty Coffee Association) golden ratio is 1:18 (55g per liter). Most specialty baristas use 1:15 to 1:17 depending on roast and preference.
How does grind size affect taste?
Finer grind = more surface area = faster extraction = stronger/bitter. Coarser grind = less extraction = lighter/sour. Match grind to brew time.
