Medium grind coffee strikes the perfect balance between the rich, bold flavors of a coarse grind and the smoothness of a fine grind. This grind size is ideal for brewing methods that require a bit more time for extraction, such as the pour-over or press pot. However, achieving the right balance with medium grind can be a delicate art. In this guide, we'll explore the key brewing parameters, step-by-step instructions, and common pitfalls to help you elevate your medium grind coffee experience.
Overview & Background
Medium grind coffee beans are typically used in brewing methods that require a moderate extraction time. The grind size is slightly coarser than fine grind but finer than coarse grind. This size allows for a good balance between rapid extraction and even brewing, making it versatile for various brewing methods. The choice of grind size is crucial as it affects the contact time between the water and the coffee grounds, which directly influences the flavor profile of the final cup.

Step-by-Step Guide
1. Grind Your Coffee
Start by grinding your coffee beans to a medium size. This can be achieved using a burr grinder, which is preferred for consistent grind size. A good rule of thumb is to set the grinder to a size where the grounds are slightly larger than granulated sugar.
2. Preheat Your Equipment
Preheating your equipment, such as your pour-over dripper, carafe, and kettle, helps maintain the optimal water temperature throughout the brewing process. This step ensures that the water temperature remains consistent from the start to the finish.
3. Measure Your Coffee and Water
Use a scale to measure your coffee and water. For a standard 8-ounce cup of coffee, use about 15-18 grams of coffee beans and 120 grams of water. Adjust these amounts based on your personal taste preferences.
4. Rinse Your Filter
Rinse your coffee filter with hot water to remove any paper taste and to preheat the filter. This also helps to wash away any excess oils from the coffee grounds.
5. Add Coffee and Water
Add your ground coffee to the filter and pour the hot water evenly over the grounds in a circular motion. Let the water sit for about 30 seconds to allow the coffee to bloom. This step helps to release gases and aromas from the coffee grounds.
6. Continue Brewing
Slowly pour the remaining water over the grounds, maintaining a gentle stream. Continue this process until all the water has been added. The total brewing time should be around 3 to 4 minutes.
Pro Tips & Common Mistakes
Pro Tips
- Use a burr grinder for consistent grind size.
- Preheat your equipment to maintain a consistent water temperature.
- Use fresh, high-quality coffee beans for the best flavor.
Common Mistakes
- Over-grinding the coffee, which can lead to a bitter and over-extracted taste.
- Using water that is too hot, which can burn the coffee and result in a harsh flavor.
- Not allowing enough time for the coffee to bloom, which can lead to under-extraction and a weak flavor.
