Want to take your pour over coffee to the next level? In this post, we'll provide an in-depth guide and tips on how to grind coffee for pour over, so you can achieve a rich and flavorful cup of coffee every time.
Why Grinding Coffee for Pour Over Matters
Grinding coffee for pour-over brewing is an essential step to ensure that you get the most desirable flavors and nuances from your coffee beans. Understanding the impact of grind size on the extraction process, and how it affects the brew time, is vital for making a delicious cup of pour-over coffee.
The Role of Grind Size in Flavor Extraction
The grind size plays a significant role in extracting flavors from your coffee beans. It directly influences the surface area that comes into contact with water during the brewing process. A larger surface area results from a finer grind, making the coffee beans more soluble in the water.
However, grinding coffee too fine for a pour-over brewing method can lead to over-extraction, which causes your coffee to taste bitter and hollow. Conversely, if your coffee is ground too coarse, the water will move through the beans too quickly, under-extracting the potential flavors and leaving you with a weak, sour cup of coffee. Hence, finding the right grind size for pour-over brewing is crucial to achieving a balanced extraction and the desired flavor profile.
Impact on Brew Time
Brew time is another factor to consider when grinding coffee for pour over. Pour-over coffee, as opposed to immersion methods like the French press, requires a continuous saturation of the coffee grounds with fresh water throughout the brewing process. This method promotes a faster, more efficient extraction of flavors, making it necessary to control the grind size accordingly.
A finer grind will slow down the water flow, prolonging the brewing time and increasing the risk of over-extraction. On the other hand, a coarser grind will speed up the water flow, potentially under-extracting the coffee and leaving you with a sub-optimal flavor. Consequently, it's essential to strike a balance between grind size, water temperature, and brew time to achieve the best-tasting pour-over coffee.
When grinding coffee for pour-over brewing, it's crucial to consider the relationship between grind size, flavor extraction, and brew time. Striving for the ideal balance of these factors will help you achieve a satisfying, flavorful cup of coffee with the nuanced characteristics that make pour-over brewing so popular among coffee enthusiasts.
Finding the Perfect Grind Size
Finding the perfect grind size for pour-over coffee can significantly impact the taste and quality of your brew. It is important to understand the difference between coarse and fine grinds, as well as the ideal grind size for pour-over coffee.
Coarse Grind versus Fine Grind
A coarse grind has larger coffee particles, often resembling sea salt or coarse sand in texture. This type of grind allows water to flow through the coffee grounds quickly, which can result in a lighter-bodied and more acidic coffee. On the other hand, a fine grind consists of smaller coffee particles with a texture similar to table salt or even flour. Fine grinds can slow down water flow and lengthen extraction time, resulting in a stronger, more full-bodied coffee flavor.
Factors such as the brewing method, taste preferences, and coffee bean type can influence whether you choose a coarse or fine grind for your coffee. However, for pour-over brewing, a specific grind size is recommended to achieve the best results.
The Ideal Grind Size for Pour Over
For pour-over coffee, a medium to medium-fine grind size is generally recommended. This type of grind allows for a controlled, yet steady water flow through the grounds, optimizing flavor extraction, and balancing acidity and bitterness levels. When comparing textures, the ideal pour-over grind should be finer than coarse sea salt and slightly more coarse than table salt.
Here is a list to better illustrate the ideal grind sizes for different brewing techniques:
- Coarse grind: French press, percolator
- Medium grind: Drip coffee maker, siphon
- Medium-fine grind: Pour-over, Aeropress (with longer brew times)
- Fine grind: Espresso, Aeropress (with shorter brew times)
- Extra-fine grind: Turkish coffee
It's essential to use a high-quality burr grinder to achieve a consistent grind size. Blade grinders can result in a less uniform grind, negatively impacting the overall flavor of your pour-over coffee. By understanding the relationship between grind size and coffee brewing techniques, you can better tailor your coffee grounds to deliver the best possible pour-over experience.
Grinding Techniques and Tools
Pour over coffee requires a specific grind size and consistency to achieve the best extraction and flavor. This section provides information on grinding techniques and tools, focusing on burr grinders and the differences between manual and electric grinders.
Using a Burr Grinder
Burr grinders are the preferred choice for grinding coffee beans for pour over brewing. These grinders consist of two wheels or conical grinding elements that crush the coffee beans without causing frictional heat, which could affect the beans negatively. Burr grinders provide a consistent grind size and even particle distribution, resulting in better extraction during the brewing process.
To achieve the best grind for pour over coffee, aim for a medium grind size. This will allow the water to pass through the coffee grounds at the right pace, extracting optimal flavor. According to Kruve's study, grind size can be measured in microns, and a visual comparison can be made by laying out grounds and using a ruler's millimeter side. However, it can be a messy process, and precision may not be necessary for home brewing.
Manual versus Electric Grinders
Both manual and electric burr grinders can produce quality grounds for pour over coffee. The decision between the two types of grinders depends on personal preference, budget, and convenience.
Manual grinders, also known as hand grinders, are generally more affordable and portable options. They offer the control to grind coffee beans at the desired consistency, but they require more time and effort. Manual grinders typically have a conical burr design, providing even particle sizes necessary for pour over coffee.
Electric grinders, on the other hand, are more expensive but offer greater convenience and speed. Many models allow you to set the desired grind size, and the machine will produce a consistent grind at the push of a button. Electric grinders are available with either flat or conical burr designs.
When choosing between manual and electric burr grinders, take into consideration factors such as budget, convenience, and personal taste. Both options can provide the ideal coffee ground consistency and size for pour over brewing, ensuring a delicious cup of coffee.

Troubleshooting and Adjustments
Over-Extraction versus Under-Extraction
Grinding coffee for pour over brewing requires attention to detail and proper adjustments to extract all of the desirable flavors without over or under-extraction. Over-extraction happens when too many dissolved solids, making the coffee taste bitter, are released from the ground coffee. On the other hand, under-extraction occurs when too few dissolved solids are released, resulting in acidic or sour flavors.
Understanding the grind size for pour over coffee is key in controlling the extraction process. A medium-coarse grind, resembling sea salt, is generally recommended for pour over brewing. If the coffee tastes over-extracted, one should consider grinding the coffee more coarsely, whereas if the coffee is under-extracted, a finer grind should be attempted.
Tweaking Recipes for Personal Taste
Once a proper grind size is established for pour over brewing, it's important to tweak the recipe to suit personal taste preferences. This can be done by adjusting variables such as water temperature, brewing time, and coffee-to-water ratio.
Melitta pour over brewing, for instance, typically calls for a 1:16 coffee-to-water ratio. However, individual taste preferences may require slight adjustments to this ratio. Increasing the coffee volume will result in a stronger, more robust flavor, while decreasing the coffee volume will create a milder taste.
Similarly, water temperature can impact extraction and flavor. Generally, pour over brewing should use water heated to around 195-205°F (90-96°C). If the coffee tastes too weak or lacks complexity, consider raising the water temperature slightly. Conversely, if the coffee is too bitter or harsh, lower the water temperature a few degrees.
Brewing time is another essential factor that can be adjusted for personal taste. Pour over brewing should take anywhere from 3 to 5 minutes, depending on the desired strength and extraction level. A longer brewing time will lead to greater extraction, while a shorter brewing time will result in less extraction. To tweak the recipe for personal taste, adjust the brewing time incrementally and observe how the changes impact the flavors of the coffee.
