A Comprehensive Understanding of Coffee Grind Sizes

The following content discusses in detail all about coffee grind sizes and their importance in making the best brew.

Why Particle Size Is Crucial in Specialty Coffee?

Particle size is crucial in food science. For instance, it affects how much material you are using when depending on volumetric measurements since particle size affects the total density.

In specialty coffee, particle size matters because the surface area is an essential function of particle size. Specifically, the smaller the particles, the greater the specific surface area of your favorite coffee. This will also help you make the perfect concoction in your coffee grinder.

So, why is a surface area crucial for a good brew? The bigger the coffee surface area, the greater the water exposure. Likewise, the finer the grind size, the more packed and better the particles are, and the less quickly water can pass between particles, improving the amount of contact between coffee and water. This allows enjoying the perfect coffee in the coffee machines.

In contrast, the specific surface area gets significantly smaller with bigger coffee particles. Thus, there’s a lower surface area in contact with the water. Since water can pass swiftly between coffee particles, contact between the water and coffee is further diminished.

The scale of exposure between the water and coffee is relevant because the more there is contact between them, the better flavors the water can absorb from the coffee.

Is More Water-Coffee Contact Needed?

As mentioned above, the better the contact between water and coffee, the better flavors water can absorb from the coffee. There are times when this is not always ideal. Overexposure can sometimes result in the extraction of undesirable bitter flavors from the coffee. Speciailty coffee in Dubai is engineered to induce the best flavor profiles.

Also, underexposure is not ideal. There must be proper contact between water and coffee. Underexposure can result in the extraction of acidic and sour flavors. But, there will be none of the dark, deep and rich coffee flavors.

The key, therefore, is to properly regulate the extraction process. One of the ways you can make this right is by ensuring you are using the right grind size for your chosen brewing method.
