What is the ideal grind size for brewing with a Moka pot?

The ideal grind size for brewing with a Moka pot is a medium-fine grind. This grind size strikes a balance between extraction and resistance during the brewing process. Moka pots operate using pressure generated from steam, and the right grind helps to ensure that water flows through the coffee grounds at an appropriate rate.

If the grind is too fine, it can lead to over-extraction, resulting in a bitter flavor and potentially clogging the filter, which could prevent proper brewing. Conversely, a grind that is too coarse would not provide sufficient surface area for extraction, leading to under-extraction and a weak, watery cup.

Using a medium-fine grind allows for optimal extraction, yielding a rich and flavorful coffee that embodies the unique characteristics of the beans used. This balance is crucial for achieving that classic Moka pot brew, which is typically stronger than drip coffee but milder than espresso.
