Medium Grind Size Brewing Guide

Discover the perfect balance between boldness and finesse with medium grind size. This middle ground offers a versatile brewing experience, suitable for various methods. However, it comes with its own set of challenges, such as ensuring consistent extraction times and managing grind consistency. Follow our comprehensive guide to master the art of medium grind size brewing.

Overview & Background

Medium grind size strikes a balance between coarse and fine grinds. It's ideal for manual brewing methods like pour-over, French press, and AeroPress. The medium grind allows for a good flow of water, providing enough contact time for optimal extraction without over-extraction.

Key Brewing Parameters / Specs

• Grind Size: Medium grind, roughly the size of a grain of rice.
• Water Temperature: 90°C - 96°C (194°F - 205°F).
• Water-to-Coffee Ratio: Typically 1:15 to 1:18 (water in grams to coffee in grams).
• Contact Time: 3-4 minutes for pour-over, 4 minutes for French press.

Step-by-Step Guide

Pour-Over Method

1. Start with a clean, preheated pour-over dripper and filter.
2. Grind your coffee to a medium size.
3. Place the filter in the dripper and add the coffee grounds.
4. Slowly pour hot water over the grounds, saturating them evenly.
5. Allow the coffee to "bloom" for 30 seconds to 1 minute.
6. Pour the remainder of the water slowly and evenly over the grounds, ensuring full saturation.
7. Allow the coffee to drain into the carafe, aiming for a total brewing time of 3-4 minutes.

French Press Method

1. Preheat your French press by pouring hot water through it and then discarding.
2. Grind your coffee to a medium size.
3. Measure out the coffee and place it in the press.
4. Pour hot water over the grounds, immersing them completely.
5. Stir the coffee gently with a spoon, then let it steep for 4 minutes.
6. Press down the plunger slowly and steadily, pushing the grounds to the bottom.
7. Serve immediately.
