What Is Grind Size In Coffee?
Well, grind size has to do with the size of the coffee particles after the beans have been grounded. This also affects the flavor, aroma, and strength of your coffee.
The grind size you choose depends on your brewing method, as different methods require different particle sizes for optimal extraction. From extra coarse for cold brew to extra fine for Turkish coffee.
How Does Grind Size Affect Coffee Extraction?
The grind size directly impacts how water interacts with the coffee grounds during brewing.
When coffee grounds are in contact with water, the water extracts soluble compounds that flavor coffee. The size of the grounds determines the rate of extraction:
- Coarse grounds allow water to pass through quickly, which means less extraction time. This is ideal for methods like French press or cold brew, where you want a slower extraction to avoid over-extraction.
- Fine grounds slow down the water flow, allowing for more prolonged contact and greater extraction. This is perfect for espresso or Turkish coffee, where a quick and strong extraction is needed.
Over Vs. Under-Extraction
Over-Extraction: When coffee is over-extracted, it means too many compounds have been drawn out from the grounds.
Usually, this happens when a grind is too fine or the brewing time is too long. Over-extracted coffee normally tastes bitter, harsh, and overly strong. Because the undesirable compounds overpower the more subtle flavors.
Under-Extraction: Under-extraction occurs when not enough compounds are extracted from the coffee grounds. This can happen with a grind that is too coarse or too short of a brewing time.
Under-extracted coffee tastes weak, sour, and lacks complexity. You don’t have the depth of flavors that come from a well-extracted brew.
Blade Vs. Burr Grinder: Which One?
Well, each type has advantages and disadvantages, so let’s take a look.
Blade Grinders:
Blade grinders chop coffee beans into smaller pieces using a rotating blade.
- Pros: Blade grinders are generally more affordable and easy to use. They are also compact and work well for casual coffee drinkers.
- Cons: The grind size is inconsistent, and coarse and fine particles are mixed. This can result in uneven extraction, which can make coffee less flavorful.
Burr Grinders:
Burr grinders use two abrasive surfaces (burrs) to crush coffee beans into uniform particles. You can also adjust the distance between burrs to have your desired grind size.
- Pros: They provide a consistent grind size crucial for balanced extraction and more precise control over grind size, making them ideal for all brewing methods.
- Cons: They are typically more expensive and larger than blade grinders. However, the investment is worthwhile for anyone who prioritizes flavor and consistency.
Which One to Choose?
If you’re serious about coffee and want to ensure a consistent, high-quality cup, a burr grinder is the way to go. For those on a budget or just starting, a blade grinder can work well. However, be aware of its limitations in grind consistency.
Why Does Consistency In Grind Size Matter?
When I started using a blade grinder, like the Hamilton Beach Fresh Grind, I noticed my coffee was always hit or miss—sometimes too bitter or weak. This inconsistency comes from the uneven grind size that blade grinders produce.
In contrast, when I switched to a burr grinder, like the Breville Smart Grinder Pro, I immediately saw a difference.
The uniform grind size ensured that all the coffee particles were extracted at the same rate. This gave me a more balanced, flavorful cup every time.
Note: Consistent grind size means you avoid the issues of over-extraction (bitter flavors) and under-extraction (sour flavors), resulting in a perfectly brewed coffee that highlights the best characteristics of your beans.
For this reason, I always recommend a burr grinder for anyone serious about their coffee.
Popular Coffee Grind Sizes And Their Uses
As I said, different grinds work better for specific brewing methods. For instance, expresso needs a finer grind to extract a more favorable shot. On the other hand, a French press requires a coarse grind. So, let’s take a closer look:
Extra Coarse Grind
Extra coarse grind particles are large and chunky, similar to coarse sea salt or peppercorns.
Ideal Brewing Method: This grind size is perfect for cold-brew coffee. The long steeping time requires large coffee particles to prevent over-extraction, resulting in a smooth, mellow flavor.
Coarse Grind
Coarse grind particles are slightly smaller than extra coarse, resembling kosher salt.
Ideal Brewing Method: This grind is ideal for French press and percolators. The coarse particles allow longer brewing time without risking over-extraction, which helps maintain a balanced flavor and prevents bitterness.
Medium-Coarse Grind
Medium-coarse grind particles are about the size of rough sand.
Ideal Brewing Method: Suitable for Chemex and other pour-over methods that require a slightly longer extraction time. This grind size ensures a clear and crisp cup of coffee with well-balanced flavors.
Medium Grind
Medium grind particles are similar to regular sand.
Ideal Brewing Method: This is the most versatile grind size for drip coffee makers and siphon brewers. Medium grind balances extraction time and surface area. This works well for a wide range of brewing methods.
Medium-Fine Grind
Medium-fine grind particles are slightly finer than sand but not as fine as espresso grind.
Ideal Brewing Method: Best for cone-shaped pour-over brewers, like the Hario V60. This grind size allows for a controlled extraction, highlighting the nuanced flavors of your coffee.
Extra Fine
Extra fine grind particles are very small, almost powdery, similar to flour.
Ideal Brewing Method: Perfect for Turkish coffee and espresso. The extremely fine grind ensures maximum extraction in a short time, producing a rich and intense flavor profile.
Coffee Grind and Health Benefits
This table shows you how different grind sizes used in several brewing methods can influence the health benefits of coffee.
Grind Size | Brewing Method | Health Benefits |
---|---|---|
Extra Coarse | Cold Brew | Lower acidity, which is easier on the stomach and reduces heartburn. Contains higher levels of antioxidants. |
Coarse | French Press, Percolator | Retains essential oils, providing higher antioxidant levels and enhancing anti-inflammatory properties. |
Medium-Coarse | Chemex | Balanced extraction helps maintain a good amount of antioxidants while providing a clean and smooth flavor. |
Medium | Drip Coffee Machines | Effective extraction of beneficial compounds like chlorogenic acid, which has antioxidant and anti-inflammatory effects. |
Medium-Fine | Cone-Shaped Pour-Over | It allows for precise extraction, ensuring a high level of beneficial antioxidants and a smoother taste. |
Fine | Espresso, Moka Pot | Quick extraction preserves antioxidants, offering a concentrated source of beneficial compounds. |
Extra Fine | Turkish Coffee | Provides a rich source of caffeine and antioxidants, supporting alertness and metabolic benefits. |
