Bezzera's own brew group, actively heated. Be careful with accessories: the portafilter connection is different from an E61, they are not interchangeable. Tampers and levelers still fit, because their size refers to the basket, not the group.
Before full pressure the coffee grounds are pre-wetted with low pressure. This is done mechanically through the design of the brew group, without electronics and without adjustments. It prevents channeling in the puck, that is spots where the water breaks through too quickly.
With Flow Control you manually control how quickly the water runs through the coffee grounds: start slowly, then increase pressure. That takes the edge off acidic beans and gives you an extra adjustment. Without Flow Control the extraction runs at a fixed pressure, and that is enough for most recipes.
Copper conducts heat quickly and evenly, which is why it is the classic boiler material. It reacts more sensitively to hard water than stainless steel; a water filter or soft water significantly extends the time between descalings.
With a tank the machine does not need a water connection and can be placed anywhere there is a power outlet. For that you have to refill, and the water quality is in your hands: filtered or soft water reduces descaling.
The machine measures the amount of water that has passed through and stops automatically. This makes shots repeatable without anyone watching the scale and is the reason this technique comes from the foodservice industry.
The vibration pump is the most common type for home use: compact, affordable, reliable. It is audible, namely for the duration of the extraction, about half a minute.
The top surface of the machine is warmed by residual heat. A prewarmed cup draws less heat from the espresso, and those last degrees decide whether it still tastes the same in the glass as in the cup.
The machine switches itself off after a set time or goes into a low-power state. That saves electricity when you turn it on in the morning and then forget about it during the day. Without standby it stays on until you switch it off.
58 millimeters is the most common size. Baskets, tampers, levelers and distributors are available for it from many manufacturers, so you are not tied to an unusual size or a single supplier.
