It might seem like a simple gesture, but tamping is one of the keys to ensuring the machine delivers a masterful coffee extraction. After acquiring good beans, four steps transform those beans into the perfect cup of coffee, the second of which, after grinding, is tamping coffee.
Tamping is a delicate phase as it is the act of compacting ground coffee, before brewing. A good tamp creates an evenly compacted puck which makes the right resistance to the brewing water flow that extracts the coffee flavours.
An authentic Espresso shot requires specific dosages that have to be pressed at the right pressure. Years ago, the measurement was 7 grams per cup. Today, however, specialty coffees, shorter toasting curves, and lighter toasting colours have increased this value to 16 grams (+/- 2 grams) for two cups, as long as grain size and percolating times are respected. To give an idea of how precise the movement must be, the tamping should be firm and even, compacting the coffee perpendicular to the filter without applying unnecessary force. Think it’s impossible to be one of the few with the magic touch? Think again. Luckily, there’s a way to tamp like a pro. Whether you prefer a machine that acts independently or one that lets you interact and put your barista skills to use, De’Longhi has a machine for you.
