The best way to make a great cup of coffee is to start with freshly ground beans. Use the right grind size for your machine, and adjust the grind setting as needed for optimal extraction. Make sure you use filtered or bottled water that has been boiled and cooled before brewing. Heat up the water in the machine before adding it to the filter or portafilter. Finally, experiment with different brewing times and temperatures to find out what works best for you.
