Coffee Grind Types Explained
There are so many different coffee types and coffee grind types that we naturally had to write a blog about it! Not to be confused with the forbidden dance, grinding is the act of turning your fresh roasted coffee beans into a powdery-like substance that is ready to brew for maximum flavor.
Whole Bean
Most obvious, and the one we recommend! Grinding your own whole bean coffee ensures you brew the freshest pot of coffee around. Why, you ask? Simply because the moment you grind a coffee bean, the surface area expands monumentally exposing the fresh grounds to fresh air – and oxygen is the enemy of fresh coffee.
Espresso
Espresso grind is very fine yet you should still be able to feel small coffee grains. This grind is also very important as when brewing espresso, small changes in grind type are amplified more so than any other type of brew and going too fine may even clog your portafilter.
Turkish
Right next to Jessica Alba, this grind type holds the superfine title :) It is completely powder-like with no grains whatsoever and is primarily used in Ibiks or Cezves.
Why are flat grind knives so popular?
The flat grind’s primary bevel slopes linearly and slowly. This allows the full flat grind to pass through materials with more ease than other grinds who slope non-linearly (hollow), or at steeper angles (sabre). This is why the majority of kitchen knives are flat ground - so they can pass through food easily without much resistance.
What is a hollow grind?
Hollow grinds are best used to remove a lot of material compared to other grinds, making a better slicer. A full hollow grind goes from the edge all the way up to the spine. The Black Widow Caper pictured above is almost a full hollow grind; you can see that a bit of the stock on the spine is still left unground.
What is a chisel grind?
By using a chisel grind, you can have the blade cut away from your steadying hand, and the meat will not be sucked in on the unground side. Chisel grinds tend to be rare, and are not used very often. Think of them as a specialized grind. Typically a knife with a chisel grind has a specific purpose.
How to sharpen a convex grind?
My method to sharpen convex grinds is to take something flat with a little give, such as a thick mouse pad, and put some sandpaper or an abrasive on it and use backward strokes (away from the edge) on the knife to give it a "micro" beveled edge. You’ll of course need to go through several grits to bring the knife back up to sharp. Afterward you’ll need to strop off any burrs since you are using the backward stroke method. Gransfors also offers an Axe Sharpening stone to sharpen your axe.
What is the best slicing knife?
Hollow ground blades are fantastic at slicing. If you combine a hollow grind, a thin edge, and a nice deep belly, it will be one of the best slicing knives you have ever had. One advantage of the hollow grind is that the blade does not increase in thickness as dramatically as other grinds do.
How to tell if a grind is hollow?
To make a hollow grind, the blade blank is applied to the surface of a grinding wheel or a belt passing around a wheel, taking a concave scoop out of the blade. The depth of the hollow will depend on the circumference of the wheel. This means that many hollow grinds will be very shallow, and indeed on many blades it is difficult for the unpracticed eye to spot a hollow grind. An easy way to check if a blade is hollow ground is to see how the light reflects off of it. Does it reflect from the whole surface, or does it bend as you move the blade up and down? If the light reflection bends it is a hollow grind. Hollow grinds are best used to remove a lot of material compared to other grinds, making a better slicer.
What blades use hollow grinds?
Hollow grinds are common on hunting and skinning knives for this reason. Another blade that uses the hollow grind is the straight razor. The extremely thin edge you can achieve with a hollow grind allows for easy push cutting with the straight razor.
Brewing is Extraction
Regardless of the brewer that you’ve chosen, brewing coffee can always be thought of more specifically as the process of extraction.
How to Judge Your Extraction
There's tons of brewing science out there to read through, and a lot of it will likely give you concrete numbers to shoot for like 20% extraction yield and 1.3% TDS.
The Importance of Strength
An ideally extracted dose of coffee might be the first goal in brewing, but ensuring that you brew coffee with good strength is certainly a close second.
Mastering Your Flat-Bottomed Brewer
Learning to thrive with your brewer is all about learning to accept the variables that you can’t control, while working to influence the variables (and their relationships) that you can.
Get Brewing!
You can read all of the brewing theory out there and it wouldn’t make a difference if you never get your hands on a kettle, so get brewing! Hopefully now with a little understanding of extraction and strength, guidelines for how to taste and assess your brew, and an overview of the variables you can adjust with your flat-bottomed brewer, you’re prepared to get started on your journey toward total percolation precision..
What is a flat grind?

How to sharpen a hollow ground razor?
How to sharpen it: Traditionally, hollow-ground straight razors have been sharpened on leather strops, aided by abrasive stropping compound. Most of the hollow-ground knives produced today have a secondary V-bevel at the edge, and so can be sharpened on a stone or other flat hone, or by using a guided sharpening system. Because a hollow-ground blade has the potential to be extraordinarily sharp, however, it can benefit greatly from stropping.
How to sharpen a double bevel?
How to sharpen it: As with a V-bevel, a double-bevel grind can be sharpened on a stone or other flat hone, or by using a guided sharpening system. Generally speaking, only the secondary bevel (the one producing the cutting edge) will require attention.
What is double bevel grind?
What it is: A double-bevel grind, also known as a "compound grind," can, in overall profile, incorporate virtually any other grind -- flat, hollow, convex -- with the addition of a secondary V-bevel to produce a cutting edge.

Bevel – Teeth can have a single bevel, two bevels or no bevel at all. Types of bevels can alternate from tooth to tooth on a given blade.
What is the bevel on a knife?
The bevel is what gives a blade its specific cutting pattern. Gullet – This is the space between teeth that clears the work piece of chips after the cut. The deeper the gullet, the more efficiently chips are cleared. Kerf – This is the face of the tooth, where the actual cutting takes place.
