Espresso
Espresso (also known as a short black or single shot) is the quintessential unadulterated coffee. An intense shot of concentrated coffee with a layer of crema, espresso is the flavour base of other coffee beverages like the cappuccino, the flat white, and the latte
Tip - For optimal flavour, control the speed of the espresso flow. Generally, grinding finer will slow the flow and grinding coarser will speed it up. A good guide to start with for a double shot is 19g dose of ground coffee resulting in 38g of liquid coffee, extracted within 20-30 seconds.
