Coffee puck意思

"Coffee puck" is a term used in coffee preparation, specifically in reference to espresso making. It refers to the compacted layer of ground coffee that is left in the portafilter or espresso basket after the espresso extraction process. The puck is formed by tamping the ground coffee before brewing, which helps to ensure even extraction and pressure during the brewing process.

After the espresso is pulled, the puck can be removed and discarded, or in some cases, it can be used for making post-brew coffee beverages like Americanos or used in manual brewing methods like French press or pour-over. Some baristas also practice "puck scraping," which involves removing the top layer of the puck to ensure a more even extraction for the next shot.
