How should espresso shots typically be timed?

Espresso shots should typically be timed to extract between 15 to 26 seconds. This timing range is essential because it balances the extraction of flavors from the coffee grounds, ensuring that the resulting shot has the right combination of richness, sweetness, and acidity.

Timing is critical in espresso preparation; too short of an extraction time can lead to under-extraction, causing the shot to taste sour and lacking depth. Conversely, an extraction that is too long may result in over-extraction, leading to a bitter flavor profile.

By adhering to the range of 15 to 26 seconds, you can achieve an optimal extraction that highlights the coffee's unique characteristics while providing a satisfying crema and body. This timing standard is widely accepted in barista training and espresso guidance, making it crucial for maintaining quality in coffee preparation.
