How Do You Know What Size Tamper To Get?
Choosing the correct tamper size is important in order to achieve a consistent and even distribution of coffee grounds. The size of the tamper will depend on the diameter of the portafilter basket you are using. Most portafilters have a diameter of 58mm, which is the most common tamper size. However, some machines may have smaller or larger portafilters, so it is important to measure the diameter of your portafilter basket before purchasing a tamper. You can also consult the manual for your machine or contact the manufacturer for guidance.
