The amount of beans you use for a cup or a pot of coffee might vary based on your strength preferences, but there are certain standards that you can base your measurements off of. The legendary "golden ratio" is 17.42 units of water per 1 unit of coffee, a rather inconvenient number to wield in your brew battle but a good place to start. From there, you can decide if you prefer to alter the strength to other suggested standards, such as 8.25 grams coffee per 150 mL water (SCAA) or 1-2 tbsp coffee per 6 oz. water (NCA).
