5. **How do you prepare the perfect coffee?**
The perfect coffee brew can be very subjective and depends on personal preference. However, there are some general guidelines: use freshly roasted and ground beans, watch your coffee to water ratio (a general rule is 1 to 18), and make sure your water is the right temperature (between 90- 96 degrees Celsius).

8. **What is the difference between espresso and filter coffee?**
