This single-sided 58mm espresso tamper features a convex bottom and is a great barista tool for compressing down espresso or coffee grounds. It is perfect for use behind any espresso bar or in any cafe setting as the heavyweight stainless steel body makes this metal espresso tamper extremely durable for everyday commercial. 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!
