Determining the grind size of your coffee

Coffee Grind Size

In an effort to continually equip you all to make the BEST coffee possible here is our second part to grinding coffee properly. Having the perfect grind is important and here are the details!

What is it?

Coffee grind size is how fine or coarse your coffee bean becomes after go through a grinder.

Why is it important?

You will need different sizes of grounded beans depending on the brew method. The size of grind will affect the flavor and taste.   

How to determine the size?

The grind size will depend on the brewing method you use. As you noticed, there are overlaps on some brewing methods. The size can be determined by personal preference of how you like to drink your coffee.

How to adjust?

Extraction

A coarse grind lets the water flow much faster than the fine grind. Depending on the grind size, you would want certain amount of time for the water to be in contact with the ground. Rule of thumb, slower water flow and faster extraction time, visa versa (inverse relationship).

Water Extraction Time/Duration

Coarse

You would want to use brewing method that takes long time (at least 5 min+), such as French Press or Cold Brew (12+ hrs) to extract full flavor and taste because water flows much faster for the coarse grind. Rule of thumb, the longer water is in contact with grind the better extraction of flavor.


Medium

Medium sized grind is much more complicated compared to coarse or fine grinds but personal preference plays the difference maker. If you prefer to drink less bitter coffee, then you would fall more into medium-coarse where it extracts more of fruit flavors from the bean. On the other hand, if you enjoy bitter coffee then you would be more of medium-fine. We recommend water extraction time to be around 2 to 4 minutes, depending on your preference.   

Fine

Fine grind is only used on espresso machine and Turkish brewing method (even more finer than espresso). Water travels much slower so you want short extraction time. Espresso machine is great for fine grind due to high pressure from the machine and you only make two quick shots of espresso during the extraction time (apprx. 20-25 seconds).
