Oyster mushroom mycelium on coffee grounds. Initiatives have succeeded using coffee grounds as a substrate for the cultivation of mushrooms (including oyster mushrooms). [23] [24] The use of spent coffee grounds in this application has the advantage of the used coffee grounds needing no pre-treatment to be usable as a mushroom substrate. [6]
Filter coffee being brewed. Coffee preparation is the making of liquid coffee using coffee beans.While the particular steps vary with the type of coffee and with the raw materials, the process includes four basic steps: raw coffee beans must be roasted, the roasted coffee beans must then be ground, and the ground coffee must then be mixed with hot or cold water (depending on the method of ...
Espresso yield is generally 15–25%: [2] 25% is quoted as the Italian extraction. [9] Espresso yield has received significantly less attention in the literature than brewed coffee extraction. [9] [2] Espresso yield features a number of surprising properties: [2] yield depends primarily on depth of the "puck" (cylinder of coffee grounds);
Nestlé Nespresso S.A., trading as Nespresso, is an operating unit of the Nestlé Group, based in Vevey, Switzerland. [4] Nespresso machines brew espresso and coffee from coffee capsules (or pods in machines for home or professional use [5]), a type of pre-apportioned single-use container, or reusable capsules (pods), of ground coffee beans, sometimes with added flavorings.
Moka pots differ from espresso machines in that they brew under substantially lower pressure – 1.5 bars (21 psi) rather than 9 bars (130 psi) – and use hotter water – a mix of boiling water and steam at above 100 °C (212 °F), rather than 92–96 °C (198–205 °F) of espresso machines, similar to early steam brewing machines.
An espresso tamper, grinder, and knockbox. A knockbox (informally known as a "bash bin", "coffee column", "slam piece" or "bang bang") is a device used to store spent espresso grounds, called a puck, after a shot of espresso has been pulled.
Doppio espresso (Italian:) is a double shot which is extracted using double the amount of ground coffee in a larger-sized portafilter basket. [1] This results in 60 ml (2.1 imp fl oz; 2.0 US fl oz) of drink, double the amount of a single shot espresso. [2] Doppio is Italian multiplier, meaning 'double'.
Espresso machines use pressure to extract a highly concentrated coffee with a complex flavor profile in a short time, usually 25–30 seconds. The result is a beverage with a higher concentration of suspended and dissolved solids than regular drip coffee, giving espresso its characteristic body and intensity.
