Suppose one morning you wanted a fresh cup of coffee, but your packet of coffee grind is months old, and you don’t have any coffee grinder nearby. Definitely, you’re not going to have a premium experience. But that’s not the end of the world. Because you can grind your coffee beans at home with common kitchen tools, like a pepper grinder, and experience the true potential of your bean. But can you use a pepper grinder for coffee beans?
In short, you can! But it may not be the best solution as it takes too much time and energy. You also won’t be able to control the grind size of the beans, which could result in too coarse or too fine grounds. If you don’t have a traditional coffee bean grinder, we recommend using a mortar and pestle.
Today I will share my experience using a pepper grinder as a coffee grinder and some other effective coffee grinding methods at home you can use in a pinch.
Let’s get started.
The Theory Behind Coffee Grinds
If you want the coffee’s full flavor, then grinding is the only option you are left with.
The finer you can grind the coffee, the more particles of the coffee will be in touch with the hot water, which will release the coffee bean’s flavor. Also, it will reduce flavor-destroying oxygen to protect the natural flavors of the coffee.
But don’t get too much excited while grinding your coffee. If you make it like a powder, the particles inside the bean will be released into the air and you will lose flavor. It will also fill your cup with sediments.
Why Do Variations in Coffee Grind Size Matter?

You can’t put a packet of coffee beans and put it into hot water and expect that it will give you the ultimate coffee experience, can you?
To get the most exquisite coffee experience, you need a proper understanding of the coffee grind types and sizes. Besides, each brewing method requires different sizes of coffee grounds.
The beans and coarseness size plays a significant role in the contract and extraction time of a coffee mixture.
Types of Coffee Grinds
Author Note: Perfectly ground coffee can make your drinking experience much better. But people often get confused about the sizes of the grind. Worry not, I’ve got your back.
There are usually 5 types of grind sizes. When people want their coffees to taste bitter, they typically go for finer grinds because it allows the coffee to be over-extracted. When people want more acidic tasting coffee, they go with a coarsened version for its slow extraction properties.
And in this article, I will cover every significant grind types you will find in the market.
Grind | Description | Best use |
Extra fine Ground Coffee | It is the carbon copy of powder. And making it is straightforward; set the grinder to its finest setting. |
|
Fine Ground Coffee | It has the same size as the sugar. It takes a little bit of time to come in contact with water. If it is slightly coarser or finer, it will impact the espresso’s taste, and it will come out of the filter. |
|
Medium Ground Coffee | It is the same as sugar but slightly coarser. It is a crucial grind because if it’s too fine, it will clog the filter, and if it is too big, it won’t produce the desired taste. |
|
Coarse Ground Coffee | And, it takes a lot amount of time to be in contact with the water. |
|
Extra Coarse Ground Coffee | It is the most solid ground on the list. The coffee beans stay grinders for a couple of seconds to break up the beans. And the contact time with water is huge, taking several hours to get the flavor. |

If you are looking for a consistent grind with smaller granules and better brewing, then you should definitely invest in the actual grinder.
