A coffee distribution tool, also known as a coffee leveller, is a tool used to evenly distribute coffee grounds in the portafilter basket of an espresso machine. The tool typically has a flat or slightly curved bottom that fits into the basket and a handle that allows the user to apply pressure while twisting or rotating the tool.

The importance of using a coffee distribution tool is that it helps ensure that the coffee grounds are evenly distributed, which is essential for achieving a consistent and high-quality espresso shot. If the grounds are unevenly distributed, the water will not flow through the coffee evenly, which can result in a shot that is either over-extracted or under-extracted. Over-extracted coffee can taste bitter and unpleasant, while under-extracted coffee can taste weak and watery.

By using a coffee distribution tool, baristas can achieve a more even extraction, resulting in a better-tasting espresso shot. The tool can save time and reduce waste while improving the overall quality of your coffee.
