The Difference Between Grind Sizes and Different Brew methods
- November 8, 2024

Choosing the right grind size for your coffee can make all the difference between a perfect cup and a disappointing one. Whether you’re a casual coffee drinker or aspiring to enroll in professional barista training classes in New Jersey, understanding the basics of coffee grinding is essential. In this blog, we’ll explore why grind size matters for different brewing methods and how to achieve the ideal grind for each type of coffee preparation. This knowledge can serve you well whether you’re learning at New Jersey Coffee School or perfecting your home brewing techniques.
The Importance of Coffee Grind Size
A grind that’s too fine can lead to over-extraction, resulting in a bitter taste, while too coarse a grind may lead to under-extraction, leaving your coffee weak and watery. Understanding this balance is one of the core skills in the art of making great coffee, a concept often covered in coffee business classes in Hoboken, NJ. By perfecting your grind size, you can maximize the flavor potential of each cup and elevate your coffee experience.
Coffee Grind Sizes and Brewing Methods
1. Coarse Grind (Sea Salt Consistency)
- French Press: The larger grounds allow for a longer steep time, making it perfect for the immersion process used in the French press. A coarse grind ensures that the flavors are extracted over a longer period, giving a full-bodied, rich taste without bitterness.
- Cold Brew: A coarse grind is essential for cold brew, as the coffee is steeped in cold water for an extended period, typically 12–24 hours. This slow extraction process helps to create a smooth, less acidic brew with a mild, refreshing flavor profile.
- Percolator: Although less common these days, percolators also benefit from a coarse grind. The boiling water repeatedly circulates through the grounds, and the larger grind size prevents over-extraction, delivering a balanced and satisfying cup.
2. Medium-Coarse Grind (Slightly Finer Than Sea Salt)
- Chemex: This method, known for its clean, bright flavor, uses a thick paper filter that requires a medium-coarse grind. The slightly finer grind prevents clogging while allowing for a steady extraction, which emphasizes the coffee’s natural clarity and complexity.
- Clever Dripper: This immersion-drip hybrid method also pairs well with a medium-coarse grind. It offers a versatile brewing experience where the grounds steep for a few minutes before dripping, creating a balanced and nuanced flavor.
3. Medium Grind (Sand-Like Consistency)
- Pour-Over (V60, Kalita Wave): The medium-fine grind is perfect for pour-over methods like the V60 or Kalita Wave, allowing for a slower extraction that brings out the coffee’s complexity. These methods often emphasize delicate flavor notes, which a medium-fine grind helps to highlight.
- Aeropress (Longer Brew Time): When using an Aeropress, a medium grind works well with a longer brewing time. If you prefer a shorter brew time, you might want to use a finer grind. The medium grind provides flexibility, allowing you to adjust the brewing time to your taste preference.
Experiment with a medium grind across different brewing methods. It’s a versatile option that works well with various recipes, enabling beginners to explore and develop their coffee brewing skills.
4. Medium-Fine Grind
- Drip Coffee Makers: Most standard drip coffee machines use a medium grind, which balances extraction and flavor by allowing water to pass through steadily without clogging. It’s a staple grind size in many homes and coffee shops for its consistency and ease of use.
- Aeropress (Longer Brew Time): If you’re using a shorter brew time with an Aeropress, a medium-fine grind can help you achieve the ideal extraction. This grind is suited for those who want a faster brewing process without sacrificing flavor.
5. Fine Grind (Table Salt Consistency)
- Espresso: Espresso machines require a fine grind to push water through quickly under high pressure. If the grind is too coarse, the water will pass through too quickly, resulting in a weak flavor. A grind that’s too fine, however, can lead to over-extraction and bitterness.
- Moka Pot: The Moka pot, which uses steam pressure to brew coffee, also requires a fine grind. This grind size helps to extract coffee oils and flavors quickly, resulting in a bold, concentrated brew.
6. Extra-Fine Grind (Powdered Consistency)
- Turkish Coffee: Turkish coffee requires an ultra-fine grind because it is brewed by boiling the coffee with water and is left unfiltered. The powder-like grounds dissolve into the brew, creating a rich, full-bodied texture that sets it apart from other brewing methods.
Achieving the Perfect Grind for Each Brewing Method
1. Burr Grinders vs. Blade Grinders
- Burr Grinders: Preferred by professionals, burr grinders provide a consistent grind size by crushing beans between two abrasive surfaces. Burr grinders are precise and allow you to set specific grind sizes, making them a staple in coffee shops and barista training courses.
- Blade Grinders: While more affordable, blade grinders tend to produce uneven grind sizes. They chop the beans with a spinning blade, which makes it harder to control consistency. If you’re serious about your coffee, investing in a burr grinder is well worth it.
