„Tamper: the device used to tamp a bed of loose, finely ground coffee in a portafilter, in preparation for brewing espresso. Most espresso machines include a plastic tamper as an accessory, and after market tampers can be bought. They are measured in millimeter sizes, corresponding with the filter basket internal diameter of your espresso machine.“

„Ewan Reid, the effervescent Technical & Quality Director at Matthew Algie, bubbles into activity at the mention of tamping... "By tamping down the finely ground coffee in the portafilter, we're aiming to supplement the hydraulic pressure that will force water through the coffee to make real espresso." Hydraulics? What does he mean...? "We all know that espresso is about pressure" remarks Ewan "and to create a stable bed of ground coffee particulates we have to tamp.“

„This espresso coffee has been packed into the portafilter in such a way as to create pressure that restricts the flow of water through the coffee. The pressure is created because the coffee is finely ground and the water is not free to flow quickly through the coffee. This is where I reintroduce the term BAR pressure. In order for hot water to be pushed through the ground coffee, the pump has to be able to generate serious pressure to overcome the resistance created by the packed coffee.“

„A blind filter basket or a backflush insert - A blind portafilter is a filter basket that has no holes in it. It would obviously be no good for brewing espresso as there is no way for the water to go through it. The alternative to a blind filter is a special rubber insert that is placed in a standard basket and plugs it up much in the same way that one of the flat rubber sink stoppers work.“
