Espresso is made by passing water at high pressure through compacted ground coffee.
However, a set ‘recipe’, which usually refers to a ratio and brewing duration, is generally given by the roaster (the brands that roast and blend coffee beans). The most common recipe is 1:2 in 25 to 35 seconds, effectively turning each gram of ground coffee into 2g of liquid espresso in that period.
How compacted the ground coffee is will affect how quickly or slowly the espresso brews. If the coffee is too tightly packed, it will take longer to brew and be too strong; loosely compacted coffee means it will be dispensed too quickly and subsequently weak.
