Coffee bean size and flavor


Coffee Bean Size and Taste

When you buy coffee beans, how many of you have noticed the difference in the size of coffee beans? In fact, coffee beans are classified according to their size. It is a little difficult to tell the difference in the size of coffee beans after roasting, but it is clear in the case of green coffee beans before roasting. What is the difference between small beans and large beans? How does this affect the flavor?

Screen size

One of the terms used to describe the size of coffee beans is screen size. Screen" means "sieve," and coffee beans are sieved to a uniform size. The screen size is a very important factor in determining the grade of coffee. And the size standard differs from country to country.

19 7.5mm

17 6.75mm
16 6.5mm

13 5mm

Tanzania

A 6.25 mm to 6.74 mm

C 5.9mm to 6.14mm

As you can see, standards and descriptions differ by country. The grade of the coffee bean is determined by the screen size, elevation, number of defects, and other factors.

Differences in Taste by Size

The actual taste of coffee beans from all major coffee countries by size is almost the same, and the main focus is on appearance. When coffee beans are lined up in a row, the larger and fuller beans are more beautiful and eye-catching than the smaller and smaller beans.

In recent years, however, with the rise of specialty coffees, more and more people are focusing on taste and flavor rather than size, so size is not so important to them.

After all, coffee is something to be enjoyed by drinking, not by decoration, so "taste" has a high priority.
