Yes, you can use ground coffee in a Capresso espresso machine, but it is important to ensure that the coffee is ground to the appropriate fineness for espresso. The ideal grind size for espresso is usually fine, resembling table salt, as it allows for the optimal extraction during brewing. Using coffee that is too coarse can result in weak espresso, while coffee that is ground too fine can lead to over-extraction and a bitter taste.
It is also advisable to evenly distribute and tamp the ground coffee in the portafilter to achieve the best flavor profile when brewing. Additionally, Capresso espresso machines typically offer the flexibility of using both ground coffee and coffee pods, depending on the model. Each machine may have its own specific instructions regarding the use of ground coffee, so it is beneficial to refer to the user manual for guidance. You can find more detailed instructions on the current Capresso website.
