1.15 – 1.18 brew ratio(what does 1 signify)
1:15 – 1:18 coffee-to-water brew ratio, the 1 signifies one part coffee by weight.
This means for every 1 gram (or any unit of weight) of coffee grounds, you use 15 to 18 grams of water.
- 1 Part Coffee (The ‘1’): Represents the weight of your dry coffee grounds (e.g., 20g).
- 15–18 Parts Water: Represents the weight of the water used to brew (e.g.,
20g×15=300g of water).
Key Takeaways regarding this Ratio:
- 1:15: Results in a stronger, more concentrated cup.
- 1:18: Results in a milder, more balanced cup, often considered the “Golden Ratio” by the Specialty Coffee Association (SCA).
