Medium-coarse grind size brewing techniques: Ultimate Brewing Guide & Expert Tips (2026)

When it comes to brewing techniques, the medium-coarse grind size strikes a perfect balance between the rich, bold flavors of a coarse grind and the bright, nuanced notes of a fine grind. This grind size is particularly suited for methods that require a bit of texture in the final cup, such as French presses and pour-overs. However, mastering the art of using medium-coarse grind requires attention to detail, especially when it comes to water temperature and brewing time, to ensure that the coffee is neither too bitter nor too weak.

Overview & Background

The medium-coarse grind size is a versatile choice that offers a good middle ground between grind sizes. It's ideal for brewing methods that benefit from a bit of sediment in the final cup, such as French presses and pour-overs. This grind size allows for a slower extraction process, which can help in bringing out more complex flavors and aromas without overwhelming the palate with bitterness.

Key Brewing Parameters / Specs

• Grind Size: Medium-Coarse
• Water Temperature: 90-96°C (194-205°F)
• Brewing Time: 2-4 minutes
• Coffee to Water Ratio: 1:15 to 1:18 (grams of coffee per liter of water)

Step-by-Step Guide

French Press

1. Grind: Start with 25 grams of medium-coarse coffee per 350-400ml of water.
2. Temperature: Heat water to 90-96°C (194-205°F).
3. Brewing: Add the ground coffee to the French press and pour the hot water over it, making sure to wet all the grounds evenly. Let it steep for 4 minutes.
4. Stirring: During the first minute, gently stir the mixture to help release the coffee oils.
5. Plunge: After 4 minutes, plunge the French press slowly and steadily to separate the grounds from the liquid.

Pour-Over

1. Grind: Use 25 grams of medium-coarse coffee per 350-400ml of water.
2. Temperature: Heat water to 90-96°C (194-205°F).
3. Filter: Place a filter in the pour-over dripper and wet it with hot water, then discard the water.
4. Brewing: Add the coffee grounds to the filter, then pour the hot water in a circular motion, covering the grounds evenly. Let it steep for 2 minutes.
5. Second Pour: After 2 minutes, pour the remaining hot water over the grounds in the same circular motion, allowing it to steep for another 2 minutes.

Pro Tips & Common Mistakes

• Consistency: Always grind your coffee to a consistent medium-coarse size to ensure even extraction.
• Temperature Control: Maintain a consistent water temperature of 90-96°C (194-205°F) to avoid over-extraction or under-extraction.
• Avoid Over-Brewing: For French presses, do not plunge immediately after 4 minutes; for pour-overs, avoid over-pouring to prevent over-extraction.
• Use Fresh Water: Always use fresh, filtered water to enhance the flavor of your coffee.
