Introduction

This tutorial explores the impact of grind size on the flavor of coffee brewed using the V60 manual brewing method. Understanding how grind size influences extraction can significantly improve your coffee experience. This guide will help you experiment with different grind sizes and evaluate their effects on taste.

Step 1: Understand Grind Size

Grind size is a crucial variable in coffee brewing that affects extraction and flavor.

  • Coarse Grind: Ideal for longer brew times, such as French press.
  • Medium Grind: Suitable for methods like drip coffee.
  • Fine Grind: Best for quick extraction techniques like espresso.

Practical Tip

Experiment with different grind sizes to find what suits your taste preferences.

Step 2: Prepare Your Equipment

Gather the necessary tools for your manual brew.

  • V60 Dripper: A cone-shaped dripper for coffee.
  • Coffee Scale: To measure coffee and water accurately.
  • Hot Water Kettle: For precise temperature control.
  • Coffee Grinder: To adjust grind size as needed.
  • VST Refractometer: For measuring extraction levels (optional but recommended).

Common Pitfall

Ensure your grinder is clean to avoid flavor contamination from previous brews.

Step 3: Select Your Coffee Beans

Choose high-quality coffee beans to get the best flavor.

  • Single Origin: Allows you to taste unique flavors from specific regions.
  • Freshness: Use freshly roasted beans for optimal flavor.

Practical Tip

Experiment with different beans to identify flavor profiles you enjoy.

Step 4: Perform a Sensory Test

Conduct a sensory test to evaluate the flavors produced by different grind sizes.

  1. Brew a Sample: Use a specific grind size and brew a cup.
  2. Taste and Note: Pay attention to the flavor notes, acidity, and body.
  3. Repeat: Change the grind size and repeat the process.

Common Pitfall

Avoid brewing too many samples at once, as palate fatigue can affect your evaluation.

Step 5: Measure Extraction with VST Refractometer

If you have a VST Refractometer, use it to measure the extraction percentage.

  1. Brew Coffee: Use the grind size you want to test.
  2. Cool Sample: Allow the brewed coffee to cool to room temperature.
  3. Measure: Follow the instructions to read the extraction percentage.

Practical Tip

Aim for an extraction rate between 18-22% for optimal flavor.

Conclusion

Grind size plays a significant role in the flavor profile of your coffee. By understanding and experimenting with different grind sizes, you can enhance your manual brewing technique. Remember to keep track of your findings and adjust based on your personal taste preferences. Happy brewing!
