Introduction to Pour Over Coffee
Pour over coffee has become increasingly popular among coffee enthusiasts in recent years, and for good reason. This manual brewing method allows for a high degree of control over the brewing process, resulting in a clean and nuanced cup of coffee. One of the key factors in achieving the perfect pour over is the size of the coffee grounds. In this article, we will delve into the world of coffee grind sizes and explore the optimal size for pour over brewing.
Understanding Coffee Grind Sizes
Coffee grind sizes can be broadly categorized into several groups, ranging from very fine to very coarse. The grind size is typically measured in terms of the diameter of the particles, with smaller diameters indicating a finer grind. Here is a general breakdown of the different grind sizes:
- Extra fine: 0.1-0.3 mm (similar to powdered sugar)
- Fine: 0.3-0.5 mm (similar to granulated sugar)
- Medium: 0.5-1.0 mm (similar to kosher salt)
- Coarse: 1.0-1.5 mm (similar to sea salt)
- Extra coarse: 1.5-2.0 mm (similar to small pebbles)
The Importance of Grind Size in Pour Over Brewing
The grind size of the coffee is crucial in pour over brewing, as it affects the flow rate of the water and the extraction of the coffee solids. A grind that is too fine can lead to over-extraction and a bitter taste, while a grind that is too coarse can result in under-extraction and a weak taste.
Optimal Grind Size for Pour Over
So, what is the optimal grind size for pour over brewing? The answer depends on several factors, including the type of pour over dripper being used, the coarseness of the coffee beans, and the desired flavor profile.
- General guidelines: A medium to medium-coarse grind is generally recommended for pour over brewing. This grind size allows for the right balance of flow rate and extraction.
- Specific guidelines: For a Hario V60 or similar dripper, a medium-coarse grind (around 0.8-1.0 mm) is recommended. For a Chemex or similar dripper, a medium-fine grind (around 0.5-0.7 mm) is recommended.
Factors Affecting Grind Size
Several factors can affect the optimal grind size for pour over brewing, including:
- Coffee bean origin: Coffee beans from different regions and farms can have varying levels of density and hardness, which can affect the grind size.

What is the ideal coffee-to-water ratio for pour-over brewing?
The ideal coffee-to-water ratio for pour-over brewing is a matter of personal preference, but a general guideline is to use 1:15 to 1:17 coffee-to-water ratio. This means that for every gram of coffee, you should use 15-17 grams of water. However, you can adjust this ratio to suit your taste preferences. Some people prefer a stronger brew and use a 1:12 ratio, while others prefer a weaker brew and use a 1:20 ratio.
It’s also worth noting that the grind size of your coffee can affect the coffee-to-water ratio. A finer grind will require a slightly lower ratio, while a coarser grind will require a slightly higher ratio. Experimenting with different ratios and grind sizes can help you find the perfect balance for your pour-over brewing.
How does the grind size of my coffee affect the flavor of my pour-over?
The grind size of your coffee plays a crucial role in determining the flavor of your pour-over. A grind that is too fine can lead to over-extraction and a bitter taste, while a grind that is too coarse can lead to under-extraction and a sour taste. A medium-coarse grind is usually ideal for pour-over brewing, as it allows for the right amount of extraction and a balanced flavor.
The grind size can also affect the flow rate of the water through the coffee grounds. A finer grind can slow down the flow rate, leading to a longer brewing time, while a coarser grind can speed up the flow rate, leading to a shorter brewing time. Finding the right grind size can help you achieve the perfect balance of flavor and brewing time.
What is the difference between a burr grinder and a blade grinder?
A burr grinder and a blade grinder are two different types of grinders used to grind coffee beans. A burr grinder uses two abrasive surfaces to crush the coffee beans, resulting in a consistent grind size and a more flavorful cup of coffee. A blade grinder, on the other hand, uses a spinning blade to chop the coffee beans, resulting in an inconsistent grind size and a less flavorful cup of coffee.
Burr grinders are generally preferred over blade grinders for pour-over brewing because they produce a more consistent grind size, which is essential for achieving the right flavor and brewing time. Blade grinders can generate heat, which can damage the coffee beans and affect the flavor of the coffee. Burr grinders, on the other hand, produce minimal heat and preserve the flavor and aroma of the coffee beans.
