What is a coffee knockbox?
A knock box is used for removing spent espresso pucks from the portafilter basket. Because espresso shots are pulled at nine bars of pressure (around 500 pounds of direct force), the spent pucks often become attached to the inside of the espresso basket and need a good solid whack to shake them free. A coffee knock box is needed to dispose of your used coffee grounds after you have made an espresso and is usually conveniently placed next to the espresso machine so you can quickly make another shot without hurrying to the bin.It is typically a cylindrical container with a bar across the top that is used to knock or tap the portafilter (the device that holds the coffee grounds and attaches to the espresso machine) against to release the spent grounds. The spent grounds are collected in the container for easy disposal.A coffee knock box provides a contained and controlled environment for puck disposal. By directing all spent grounds and any residual drips into a single receptacle, it effectively prevents widespread splashes and keeps the entire coffee station impeccably tidy and spotless.Regardless of the design or material, it is crucial to empty a knock box regularly. Hot, wet espresso pucks create an ideal breeding ground for mold, so aim to empty it every 2-3 days at the latest, even if it is not completely full, to maintain hygiene.A knock box is used for removing spent espresso pucks from the portafilter basket.

Why did Muslims drink coffee?
Historically, coffee as a hot beverage was introduced to the world by the Sufi saints in 15th-century Yemen. They drank qahwa, the Arabic term for coffee, to stay awake during the night-long meditation and recitation zikr rituals (Ralph Hattox, 1985). Arabic coffee, also called Qahwa (Arabic: قهوة), is a version of the brewed coffee of Coffea arabica beans. Most Arab countries throughout the Middle East have developed distinct methods for brewing and preparing coffee. Cardamom is an often-added spice, but it can alternatively be served plain or with sugar.
