What Grind for Pour Over: Master Your Perfect Coffee
Struggling to figure out what grind for pour over will make the perfect cup? You’re not alone; many coffee lovers find their brew is either too bitter or disappointingly sour. This frustration often comes down to one critical variable.
The ideal starting point for pour over coffee is a medium-coarse grind, which has a texture similar to coarse sand or kosher salt. This specific size is the key to controlling coffee extraction. It allows water to flow through the grounds at a rate that extracts sweet, complex flavors without pulling out unwanted bitterness.
Based on an analysis of current methodologies and hands-on testing, this guide breaks down the exact process. You will discover not just what the right grind looks like, but how to adjust it based on taste. This reveals the framework for mastering your pour over, no matter which brewer you use.
Key Facts
- The Gold Standard Grind Size: Industry analysis reveals that a medium-coarse grind is the universal starting point for pour over coffee, balancing brew time and flavor extraction.
- Extraction is Flavor: Research indicates that sour coffee is under-extracted (grind is too coarse) and bitter coffee is over-extracted (grind is too fine), making taste the best diagnostic tool.
- Consistency is Crucial: Data shows that burr grinders are essential for pour over, as their uniform grind size prevents the uneven extraction that causes off-flavors. Blade grinders create inconsistent particles, leading to both sour and bitter tastes in the same cup.
- Brew Time as a Signal: A total brew time between 2.5 and 4 minutes is a strong indicator of a proper grind size for most pour over methods.
- Equipment Matters: Brewer design directly impacts the ideal grind. For example, the thick filters of a Chemex require a coarser grind than the thin, fast-flowing filters of a Hario V60.

What Is the Right Grind for Pour Over Coffee?
The right grind for pour over coffee is a medium-coarse consistency, similar to the texture of rough sand or sea salt. This size provides the optimal balance between water flow and flavor extraction for most pour over brewers. A grind that is too fine will lead to over-extraction and bitterness, while a grind that is too coarse will result in under-extraction and a sour taste.
Think of coffee extraction like making tea; the grind size determines how long the water and coffee are in contact. A medium-coarse grind creates enough surface area for water to extract desirable sugars and flavor compounds. At the same time, it is porous enough to let water flow through in a reasonable timeframe, typically between 2.5 and 4 minutes. This process prevents the water from lingering too long and extracting the bitter compounds that hide deeper within the coffee grounds.
Mastering this balance is the first step toward a consistently delicious cup. Key characteristics of the ideal pour over grind include:
- Visible Particles: You should be able to see individual, distinct particles of coffee.
- Gritty Texture: It feels like coarse sand or kosher salt when rubbed between your fingers.
- Even Flow: When you brew, water should flow steadily through the grounds, not get stuck or rush through.
- Balanced Brew Time: It enables a total brew time that falls within the 2.5 to 4-minute “sweet spot.”
Pro Tip: Always treat the “medium-coarse” recommendation as your starting line, not the finish line. Every coffee bean and grinder is different. The true perfect grind is one that you “dial in” by tasting your coffee and making small adjustments.
How Can You Visually Identify the Correct Pour Over Grind Size?
Visually, a medium-coarse grind for pour over should look like coarse sand or kosher salt, with distinct, individual particles. When you spread a pinch of the grounds on a white plate, they should appear mostly uniform in size. There should be very few fine, powdery particles, which are known as “fines,” or large, jagged chunks, often called “boulders.”
In our testing, we find that comparing your grind to common household items is the most practical way to gauge the size without specialized tools. This hands-on check helps build an intuitive sense of the correct texture. An inconsistent grind, with both dust and chunks, will lead to uneven extraction, where some grounds give off bitter flavors while others give off sour ones. The goal is uniformity.
This table provides a clear visual guide to help you identify if your grind is in the right zone.
| Grind Level | Visual Comparison | Resulting Taste Profile |
|---|---|---|
| Too Coarse | Cracked Peppercorns | Sour, Watery, Under-developed |
| Just Right | Coarse Sand, Kosher Salt | Balanced, Sweet, Complex |
| Too Fine | Table Salt, Flour | Bitter, Harsh, Muddy |
Try This at Home: Grind a small amount of coffee at three different settings on your grinder. Place them side-by-side on a white piece of paper and label them with the setting number. This creates a personal visual reference chart that will help you make faster, more confident adjustments in the future.
How Do You Adjust Your Grind for Perfect Extraction?
To adjust your pour over grind, you must use taste as your primary guide. If your coffee tastes unpleasantly sour, your grind is too coarse, and you need to adjust it finer. If your coffee tastes bitter and harsh, your grind is too fine, and you must adjust it coarser. This simple diagnostic process is what baristas refer to as “dialing in.”
Real-world experience shows that relying on taste is the most effective method because it tells you exactly what happened during the extraction process. While brew time is a helpful secondary indicator (aiming for 3 to 4 minutes), the final flavor in the cup is the ultimate truth. The goal is to find the grind setting that produces a balanced, sweet, and complex cup.
Follow this simple framework to fix your brew:
1. If it’s Sour (like an unripe lemon): Your grind is too coarse. Adjust your grinder to a finer setting to increase extraction.
2. If it’s Bitter (like aspirin): Your grind is too fine. Adjust your grinder to a coarser setting to decrease extraction.
Common Mistake: A frequent error is changing multiple variables at once, such as grind size and coffee dose. When dialing in, only change the grind setting between brews. This is the only way to know for sure what impact the adjustment had.
How Do You Fix Sour or Under-Extracted Coffee?
Sour-tasting pour over is a classic sign of under-extraction, and the primary solution is to make your coffee grind finer. Under-extraction occurs when water passes through the coffee grounds too quickly, failing to dissolve enough of the sugars and deeper flavor compounds needed to balance the coffee’s natural acids. This results in a brew that can taste sour, salty, or thin.
By adjusting your grinder to a finer setting, you increase the coffee’s total surface area. This slows down the water’s flow, increasing the contact time and allowing for a more complete and balanced extraction. For example, if your sour brew was made with your grinder set to ’18’, try moving the setting to ’16’ for your next attempt. This small change can make a significant difference.
Indicators of sour, under-extracted coffee include:
* A sharp, acidic taste, similar to an unripe fruit.
* A brew time that is too short, often under 2 minutes and 30 seconds.
* A thin, watery body that lacks sweetness.
How Do You Fix Bitter or Over-Extracted Coffee?
Bitter or harsh-tasting pour over indicates over-extraction, which is fixed by making your coffee grind coarser. Over-extraction happens when the grind is too fine, causing water to have too much contact time with the coffee. This extended brew allows the water to dissolve not just the good flavors but also the undesirable bitter compounds, resulting in a cup that tastes astringent, dry, or hollow.
To solve this, adjust your grinder to a coarser setting. This allows water to flow more quickly through the grounds, reducing the overall extraction and preventing those bitter elements from dominating your cup. As a practical example, if your bitter brew was made with a grinder setting of ’12’, try adjusting it to ’14’ for the next brew. This adjustment will shorten the brew time and produce a smoother, sweeter flavor profile.
Indicators of bitter, over-extracted coffee include:
* An unpleasant, lingering bitterness or a drying sensation (astringency).
* A brew time that is too long, often over 4 minutes and 30 seconds.
* A hollow or empty taste that lacks any sweetness or complexity.
How Does Grind Size Change for Different Pour Over Brewers?
Yes, the ideal grind size for pour over changes based on the brewer’s specific design, particularly its filter thickness and geometry. Brewers with thicker paper filters, like the Chemex, naturally slow down the flow of water and therefore require a medium-coarse grind to prevent the brew from stalling. In contrast, brewers with thinner filters and a faster flow rate, like the Hario V60, often perform better with a slightly finer grind to slow the brew down for proper extraction.
From years of working with different coffee equipment, it’s clear that you cannot use a one-size-fits-all approach. Understanding the physics of your specific brewer is key to mastering it. The shape of the cone and the size of the hole at the bottom also play a critical role in determining how quickly water passes through the coffee bed.
This table breaks down the recommended starting points for three of the most popular pour over brewers.
| Brewer | Filter Thickness | Recommended Grind | Target Brew Time | Resulting Profile |
|---|---|---|---|---|
| Chemex | Very Thick | Medium-Coarse | 3:30 – 4:30 min | Very Clean, Bright |
| Hario V60 | Thin | Medium | 2:30 – 3:30 min | Complex, Nuanced |
| Kalita Wave | Thin | Medium | 3:00 – 3:45 min | Balanced, Sweet |
Did You Know? The Chemex was designed by a chemist, Dr. Peter Schlumbohm, in 1941. Its iconic design and thick, bonded paper filters were engineered to remove all sediment and undesirable compounds, resulting in an exceptionally clean cup of coffee. This is why it requires a coarser grind to function as intended.
What Should You Look For in a Grinder for Pour Over Coffee?
For pour over coffee, a quality burr grinder is the single most important piece of equipment you can own because it produces a consistent and uniform grind size. Unlike blade grinders that randomly shatter beans into a mix of dust and boulders, burr grinders crush beans between two revolving abrasive surfaces. This allows for precise, repeatable adjustments and produces particles of a similar size, which is essential for achieving a balanced extraction.
Expert consensus and extensive testing confirm that grind consistency is non-negotiable for high-quality pour over. When coffee grounds are uniform, water extracts flavors from them at the same rate, leading to a sweet and balanced cup. With the inconsistent particles from a blade grinder, the fine dust over-extracts (creating bitterness) while the large chunks under-extract (creating sourness), resulting in a muddled and unpleasant brew.
When choosing a grinder for pour over, look for these key features:
* ✅ Burr Mechanism: This is the top priority. Both conical and flat burr grinders will provide the consistency needed.
* ✅ Multiple Adjustment Steps: A grinder with many grind settings gives you the precision to dial in your coffee perfectly.
* ✅ Good Reputation for Pour Over: Certain models are known in the coffee community for excelling in the medium-coarse range.
In short, investing in a reputable burr grinder is the fastest way to elevate your pour over coffee from inconsistent to exceptional.
FAQs About what grind for pour over
Can I use pre-ground coffee for pour over?
While you can, pre-ground coffee is not recommended for the best flavor. It’s often not the correct medium-coarse size for pour over and loses freshness very quickly after being ground. Using whole beans and grinding right before brewing gives you complete control over the grind size and ensures you capture the maximum aroma and flavor in your cup.
What’s the difference between pour over and drip coffee grind?
Pour over grind is typically a bit coarser than standard automatic drip coffee grind. Automatic drip machines are designed around a specific flow rate that works best with a consistent medium grind. With pour over, you are in control of the water flow, so a medium-coarse grind provides a better canvas for manipulating brew time and achieving a balanced extraction.
How does the roast level of the coffee bean affect the grind size?
Darker roasts are more brittle and extract more easily, so they often need a slightly coarser grind than light roasts. If you use the same setting for a dark roast as a light roast, you risk over-extracting it and creating a bitter, ashy cup. As a general rule, try going one or two steps coarser on your grinder for dark roasts.
How much coffee should I use for a pour over?
A great starting point for your coffee-to-water ratio is 1:16. This means using 1 gram of coffee for every 16 grams (or milliliters) of water. For a standard 12-ounce mug, this translates to about 21 grams of coffee to 340 grams of water. You can adjust this up or down to suit your personal strength preference.
Does a hand grinder work well for pour over?
Yes, a quality manual hand grinder is an excellent and often cost-effective choice for pour over. Many modern hand grinders offer exceptional grind consistency, sometimes even outperforming electric grinders at a similar price point. Their portability and quiet operation make them a favorite among coffee enthusiasts who value precision and a hands-on process.
My brew is taking too long (over 5 minutes). What’s wrong?
If your brew is taking too long, your grind is almost certainly too fine. The small coffee particles are compacting and choking the filter, which prevents water from passing through efficiently. This will inevitably lead to an over-extracted and bitter cup. To fix this, adjust your grinder to a noticeably coarser setting to speed up the flow.
Can I use an espresso grinder for pour over?
While possible, using an espresso grinder for pour over is often not ideal. Espresso grinders are engineered to make micro-adjustments in the very fine espresso range. Many have large jumps between settings when you get to the coarser pour over range, making it difficult to dial in the perfect size.
What do the numbers on my grinder mean?
The numbers on a coffee grinder represent steps of coarseness, but they are not universal across different brands or models. A ’20’ on one grinder is not the same as a ’20’ on another. It’s best to think of them as personal reference points for your machine. Start with the manufacturer’s recommendation for pour over and adjust based on taste.
Is it better to grind coarser or finer?
It is almost always better to start with a grind that is slightly too coarse and adjust finer. A brew from a coarse grind might be a little sour (under-extracted), but it is usually still drinkable. A brew from a grind that is too fine will be intensely bitter and unpleasant. Starting coarse allows you to slowly approach the “sweet spot” without ruining a cup.
Does water temperature affect my grind size choice?
Yes, water temperature and grind size are related, but you should always adjust your grind size first. Hotter water extracts flavor more efficiently. If you are using very hot water (205-212°F / 96-100°C) and your coffee still tastes sour, you definitely need to grind finer. Conversely, if your coffee tastes bitter, grinding coarser is the primary fix.
Key Takeaways: Pour Over Grind Summary
- Start with Medium-Coarse: Your universal starting point for any pour over brew is a grind with the texture of coarse sand. This is the foundation for all further adjustments.
- Taste is Your Guide: The most important rule is to let your taste buds lead. If your coffee is sour, grind finer. If it’s bitter, grind coarser. This simple feedback loop is the key to dialing in.
- Consistency is King: A quality burr grinder is the most critical investment for pour over. It provides the uniform particle size needed for a balanced extraction, something a blade grinder can never achieve.
- Brewer Determines Grind: The type of pour over device you use directly influences the ideal grind. Thicker filters like those on a Chemex demand a coarser grind, while thinner filters on a V60 require a finer one.
- Adjust for the Bean: Darker roast coffees are more soluble, so they typically require a slightly coarser grind than light roasts to avoid tasting bitter or ashy.
- Troubleshoot with Time: Use your total brew time as a secondary clue. A brew under 2.5 minutes is likely too fast (grind finer), while one over 4.5 minutes is too slow (grind coarser).
- Change One Thing at a Time: When troubleshooting, only adjust the grind size between brews. Changing multiple variables at once makes it impossible to know what change actually fixed the problem.
Final Thoughts on Mastering Your Pour Over Grind
Mastering the perfect grind for your pour over is not about finding a single magic number. It’s about learning a repeatable process. You now have the framework to start with the right foundation—a medium-coarse grind—and make intelligent adjustments based on the most important feedback tool you have: your sense of taste. By understanding the relationship between grind size, brewer type, and the resulting flavor, you have unlocked the secret to moving beyond inconsistent brews. You can now confidently troubleshoot any cup and consistently create delicious, balanced, and satisfying coffee at home.
