A tamper is an essential tool for the perfect espresso. Tamping helps ensure an even extraction. Have you ever thought about what happens when the coffee grounds are not pressed properly in the portafilter? There is a high likelihood that the water will flow through the filter very quickly. This leads to under-extraction and a watery coffee. Proper tamping ensures an even flow of water through the coffee grounds. A balanced extraction is crucial to bring out the best flavor from your coffee. This solid and durable tamper weighs 340 g, so you don't have to apply too much tamping pressure. Its flat base provides a perfectly level surface. With a diameter of 50.8 mm, the tamper is suitable for 51 mm portafilters and filter baskets, which are commonly used with many home espresso machines.
