This two-sided espresso tamper features a 50mm end and a 55mm end for compressing espresso or coffee grounds. It is the perfect barista tool to use behind any espresso bar or in any cafe setting as the heavyweight aluminium body makes this metal dual-sided espresso tamper extremely durable for everyday commercial or at home use. Traditionally an espresso tamper is used to compress espresso grounds into a densely packed "puck" which causes water to flow more slowly through it when in the portafilter of your espresso machine. This practice results in a richer flavor extraction that your patrons are sure to thank you for!
