The Effect of Portafilter Size On Espresso Extraction

The size of a portafilter basket subtly impacts espresso extraction. For example, a bigger portafilter causes better water-to-coffee interaction and extracts rich-flavored espresso.

A larger basket size, like 58mm, holds more amount of coffee grounds. Thus it creates a greater surface area for water to interact with and extract flavor. It leads to a high-quality extraction and produces a more balanced espresso shot.

In contrast, a smaller basket size, like 54mm, contains less coffee. So, the surface area becomes tiny for water to interact with. As a result, the extraction quality can alter a little, which delivers a relatively concentrated espresso shot.

But this comparison does not measure which size produces better beverages. Both sizes have pros and cons that can affect the quality of the espresso.
