What does screen size mean?

Screen size refers to the size of the holes in a sieve used to separate particles of different sizes. In the context of coffee, screen size is a critical factor influencing the quality and taste of the final product.

Why do you need to sieve coffee?

Sieving coffee is necessary to ensure even extraction. If the coffee is not sieved, some parts of the coffee can be over-extracted while others remain under-extracted, leading to an uneven taste.

The importance of screen size for coffee beans

The screen size of coffee beans can have a significant impact on the taste and aroma of the coffee. An uneven screen size can lead to uneven extraction, which in turn affects the taste of the coffee.

The role of screen size in coffee preparation

Screen size plays a crucial role in coffee preparation. It influences the extraction rate of the coffee, which in turn affects the taste and aroma of the coffee.

What classifications result from sieving?

Sieving coffee beans results in various classifications based on the size of the coffee beans. These classifications can vary from country to country, but they are usually expressed in letter combinations such as AA, A, B, and so on.

Over-extraction occurs at the screen rim due to different compression

A common mistake when preparing espresso is over-extraction at the screen rim. This happens when water flows too quickly through the coffee in the portafilter, leading to excessive extraction of the coffee at the edge of the screen. This can result in a bitter taste.

Different screen sizes for different roasts

Different coffee roasts require different screen sizes. A dark roast, for example, has a different optimal screen size than a light roast. It is important to choose the right screen size for each roast to achieve the best possible taste.

Single baskets vs. double baskets

There are also differences between single and double baskets. Single baskets generally have smaller holes and are ideal for preparing espresso. Double baskets, on the other hand, have larger holes and are better suited for coarser coffee types such as French Press or Cold Brew.

How to choose the right screen size for coffee beans

Choosing the right screen size for your coffee beans depends on several factors. These include the type of coffee you want to prepare, the type of coffee beans you are using, and your personal preferences.
