The Science Behind Hario V60 Grind Size

The Hario V60 is a popular pour-over coffee brewing method that requires precise grind size. The grind size is an essential factor that determines the final taste and quality of the coffee. In this article, we will explore the science behind Hario V60 grind size and how it affects the taste of your coffee.

The Basics of Hario V60

The Hario V60 is a cone-shaped coffee brewer invented by Hario, a Japanese company. It is a manual brewing method that requires a paper filter, a kettle, and a coffee grinder. The basic principle of the Hario V60 is to pour hot water over ground coffee beans in a filter, which extracts the flavor and aroma of the coffee.

The Importance of Grind Size in Hario V60

Grind size is one of the most crucial factors that affect the taste of your coffee when brewing with the Hario V60. The grind size determines the rate of extraction, which is how fast the water extracts the flavor and aroma from the ground coffee. If the grind size is too coarse, the water will pass through the coffee too quickly, resulting in a weak and under-extracted coffee. Conversely, if the grind size is too fine, the water will pass through the coffee too slowly, resulting in an over-extracted coffee that tastes bitter and unpleasant.

The Science Behind Grind Size

The science behind grind size is all about surface area. When you grind coffee beans, you increase the surface area of the coffee particles. The more surface area there is, the faster the water can extract flavor and aroma from the coffee. This is why a fine grind size results in a faster extraction rate, while a coarse grind size results in a slower extraction rate.

How to Determine the Right Grind Size for Hario V60

Determining the right grind size for your Hario V60 is all about experimentation. Different coffee beans and roast levels require different grind sizes. As a general rule of thumb, medium-fine grind size is ideal for most coffee beans when brewing with the Hario V60. However, this can vary based on personal preference and the type of coffee you are using.

The Bottom Line

The Hario V60 is an excellent pour-over coffee brewing method that requires precise grind size. The grind size is an essential factor that determines the final taste and quality of your coffee. By understanding the science behind Hario V60 grind size, you can brew a delicious cup of coffee every time.
