Filter Coffee Extraction ft. Hiro Lesmana | The Fundamentalist Vol. 3.2

Introduction

This tutorial will guide you through the process of mastering filter coffee extraction, inspired by insights from coffee brewing champion Hiro Lesmana. By understanding the science and experimentation behind brewing, you can refine your techniques and achieve a perfect cup of coffee every time. This guide is ideal for both coffee enthusiasts and baristas looking to enhance their skills.

Step 1: Understand Coffee Extraction

• Coffee extraction refers to the process of dissolving soluble compounds from coffee grounds into water.
• The goal is to achieve a balanced flavor profile by controlling the extraction time and water temperature.

Key components extracted include

• Sugars: Contribute sweetness.
• Acids: Provide brightness.
• Bitterness: Impacts overall taste.
• Aim for an extraction time between 2-4 minutes for filter coffee, adjusting based on the desired flavor.

Step 2: Experiment with Brew Variables

Conduct experiments by adjusting various brewing parameters

• Grind Size: Finer grounds increase extraction speed; coarser slows it down.
• Water Temperature: Aim for 195°F to 205°F (90°C to 96°C) for optimal extraction.
• Coffee-to-Water Ratio: A common ratio is 1:15 (1 gram of coffee to 15 grams of water).

Practical Tips for Experimentation

• Start with a standard recipe, then change one variable at a time.
• Keep detailed notes to track changes in flavor and extraction.
• Tasting notes can help identify what adjustments yield better results.

Step 3: Brew with Precision

• Use a scale to measure coffee and water accurately.

Ensure even saturation of coffee grounds

• Pour water in a circular motion to avoid channeling.
• Allow for bloom time (30-45 seconds) before the full pour to release CO2.

Step 4: Analyze Your Results

After brewing, taste your coffee and evaluate

• Is it too bitter, sour, or weak?
• What flavors are prominent?
• Adjust your recipe based on your tasting notes and repeat the brewing process.

Step 5: Refine Your Technique

Continuously refine your brewing method based on feedback

• Use a consistent technique for pouring and timing.
• Experiment with different coffee beans to understand how origin affects flavor.

Conclusion

By applying the principles of extraction and experimenting with your brewing process, you can significantly improve your filter coffee skills. Remember to document your experiments and refine your methods over time. Engage with the coffee community to share insights and learn from others, and you’ll be well on your way to brewing championship-level coffee!
