Gaggia Classic Pro E24 vs Breville Bambino Plus

Machine type

Heating system

The single biggest structural difference between espresso machines. Thermoblock and thermocoil designs heat water on demand, so they are ready in seconds but cannot brew and steam at once. A heat exchanger or dual boiler can do both simultaneously, at the cost of a long warm-up and a higher price.

Brew and steam at once

PID temperature control

Heat-up time (manufacturer claim)

How long from switch-on to first shot, as stated by the manufacturer. Short heat-up is the difference between espresso on a weekday and espresso only on a Sunday.

Portafilter diameter

58mm is the commercial standard, so baskets, tampers and distribution tools are easy to find and often better made. 54mm and 51mm work perfectly well but the accessory market is smaller. It changes what you can buy later far more than it changes what is in the cup.

Baskets supplied

Pre-infusion

Wetting the coffee gently before full pressure helps the puck settle so water does not carve a channel through it. Most machines that offer it do so automatically and briefly; programmable pre-infusion is a control-lover's feature.

Steam wand

An assisted wand froths milk reliably but produces bubbles rather than the dense microfoam latte art needs. A manual wand can make genuinely good milk but has a learning curve. An automatic wand hits a set temperature and texture without you standing over it.

Steam source

Grinder included

Water tank

Determines how often you refill. A small tank is a daily annoyance in a household making several drinks a day.

Width

Counter width the machine occupies.

Depth

Counter depth. The number that most often catches people out, because standard cabinets leave limited clearance.

Height

Overall height. Check it against wall cabinets, and remember the water tank often has to come out from the top.

Weight

Heavier machines are generally more thermally stable and stay put when you lock in a portafilter, but they are not moving off the counter.

Power

Draw on the circuit. Relevant if the machine shares a kitchen circuit with other high-draw appliances.

Voltage

US domestic supply is 120V. Imported machines specified at 220–240V need a transformer and are usually a mistake.

Housing material

Stainless steel housings feel and last differently from moulded plastic, and cost accordingly.

Parts & serviceability

Whether wear parts and service are realistically obtainable, which decides if the machine has a ten-year life or a four-year one.
