How much is 100 grams of coffee?

Using the 1:18 golden ratio, we get 100 grams of coffee for 12 cups. Many coffee enthusiasts swear by the “golden ratio” of coffee to water, often cited as 1:16 — one part coffee to sixteen parts water. While this is a reliable guideline, it’s not a magic formula. Even if you measure perfectly, your coffee can still taste dull, bitter, or unbalanced.
