Portafilter Bottomless for WEGA Espresso Machines

Bottemless Portafilter

There is a relatively new phenomenon among coffee enthusiasts that is not only a great Barista training tool, but is also beautiful. It is commonly referred to as a Bottomless Portafilter.

Usually a bottomless portafilter is “chopped”, or cut off, so that the entire bottom is visible. This also allows the Barista in training to see the bottom of the portafilter basket, since this is where the coffee will start it’s journey into the little espresso cup. Furthermore this allows the espresso gourmet to extract the shot more hot into the cup since the espresso extract does not get funneled through the spout of a regular portafilter which is on less temperature than the espresso shot.

First some common terms without using a bottomless portafilter:

Extraction is the act of forcing hot water from the boiler though ground coffee, which in turn “extracts” flavors, oils, colloids, lipids and other elements that turn water into brewed coffee or espresso.

Crema is one of the sure signs of a properly brewed shot of espresso (in non crema-enhancing espresso machines) and is created by the dispersion of gases- air and carbon dioxide -in liquid at a high pressure. The liquid contains emulsified oils, and forms a dark golden brown layer resembling foam on top of an espresso shot.

Golden rule is a common phrase that describes the ideal extraction time and volume for an espresso. The Instituto Nationale Espresso Italiano(PDF) provides a working definition of the characteristics of an ideal espresso, although I consider these parameters more “golden guidelines” than hard and fast rules. To keep it short: 14 grams of espresso coffeeg grind should extract a sixty milliliter double shot in 22 to 32 seconds (timing from the moment the pump starts).
