How much coffee is needed for a modern double Lungo shot?

A modern double Lungo shot typically requires a coffee dose in the range of 14 to 20 grams. This setup accounts for the longer extraction time associated with a Lungo compared to a regular espresso shot. The Lungo is designed to produce a larger volume of coffee by allowing water to pass through the coffee grounds longer, which results in different flavor profiles and stronger extraction.

Using a dose of 14 to 20 grams is essential to create the desired balance in flavor and strength; if the dose is too low, the Lungo may end up being under-extracted and taste weak. Conversely, if too much coffee is used, the extraction could become over-extracted, leading to bitterness. This range provides a suitable balance to ensure the shot is rich and flavorful while still adhering to coffee brewing standards.

The other doses mentioned in the choices either fall below or above the optimal range needed for a double Lungo, affecting the shot's overall quality and taste.
