Kind regards,

Thank you for your review and feedback, Ashraf! We are sorry that we were unable to meet your expectations this time. Please note that you can control the quality and flavor by following the next recommendations: The grind size directly affects the extraction process. A finer grind increases the surface area of the coffee, leading to a slower extraction and a stronger, more intense flavor. Conversely, a coarser grind results in a faster extraction and a milder taste. Adjusting your grinder helps you control this balance to suit your taste preferences. For a coarser grind, turn the knob to a higher number while grinding the beans. We appreciate your understanding in this matter.
