Coffee Brew Ratio 1:15 vs 1:17 – How to Choose the Right Strength for Your Taste

The coffee brew ratio — the amount of coffee compared to water — is one of the biggest factors that determines the strength and flavor of your cup. Ratios like 1:15 and 1:17 are common for manual brewing methods, but each produces a different experience. Here’s how to choose what works best for you.

Understanding the Numbers

The ratio is written as coffee : water. For example, 1:15 means 1 gram of coffee for every 15 grams (or milliliters) of water.

1:15 Ratio – Stronger Cup

• Strength: Richer, more intense flavor.

• Body: Fuller mouthfeel with more oils and solids extracted.

• Best For: Dark roasts, cold mornings, or when you want a bold cup.

1:17 Ratio – Milder Cup

• Strength: Lighter, more delicate flavor.

• Body: Cleaner and brighter, with higher perceived acidity.

• Best For: Light roasts, fruity single-origins, or when you prefer a smoother cup.

Tips for Choosing Your Ratio

• Start at 1:16 as a middle ground.

• Adjust based on roast level and personal taste.

• Use a coffee scale for accuracy — small changes can make a big difference.

Conclusion:Your ideal brew ratio depends on your preferred balance of strength, body, and clarity. Experiment with both 1:15 and 1:17 until you find your sweet spot.
