Gaggia Classic Evo Pro Review: Buy the Machine, Check the Boiler

The thing to sort out before you buy one

Gaggia has sold machines called the Classic, the Classic Pro, the Classic Evo Pro and the Classic Pro E24, and they overlap in ways that make a listing hard to read. Ninth Bar's advice is to get the seller to confirm the pressure and boiler setup in writing before money changes hands, which is unusual advice to have to give about a mainstream appliance and is the most useful sentence in any review of it.

Two things actually vary. The first is the overpressure valve. Coffeedant and Whole Latte Love both report North American units calibrated to around 9 bar, which is the pressure specialty espresso is extracted at. Ninth Bar, writing from the UK, says do not assume it.

The second is the boiler. Ninth Bar and Coffeedant both describe a coated aluminium boiler on the 2023 Evo Pro, and Ninth Bar documents units where that coating flaked. The current Gaggia North America listing specifies lead-free brass. Those are different machines wearing similar names.

None of this makes it a bad purchase. It makes it a purchase you have to pay attention to.

What you are actually buying

A 58mm commercial portafilter, a brass group, a metal chassis, and a parts ecosystem. Coffeedant's summary is that the internals are serviceable with a huge supply of parts behind them, and that is the whole argument for the machine.

Almost everything else at this price is a sealed unit. When a plastic component fails in three years you replace the machine. This one you take apart. That is why people still modify twenty year old Gaggias, and why Coffeedant frames it as a starter machine you will not outgrow.

The warm-up is not optional

The thermostat light comes on within a couple of minutes and it is lying to you.

Coffeedant puts real brew stability at 8 to 10 minutes from cold. Ninth Bar goes further and suggests 10 to 15 with the portafilter locked in, so the metal that touches your coffee is up to temperature too. Both recommend a blank shot to pull heat into the group.

Then, because there is no PID, you surf: warm the machine, flush consistently, wait for the brew light to cycle, and start every shot at the same point. Coffeedant is direct that this is the deal unless you add a PID yourself. Done consistently it works. Done carelessly it is the reason two shots from the same beans taste different.

Steaming

A full size two-hole commercial wand, which is a category above what usually appears at this price. Coffeedant timed 200ml of milk from 5C to 60C at roughly 35 to 55 seconds with reasonable technique, and got proper microfoam rather than stiff bubbles.

It is still a single boiler, so brewing and steaming cannot happen at once. For one or two drinks that is fine. For a queue of them it is the constraint.

What you will replace immediately

The tamper and the rest of the in-box accessories, which Coffeedant lists among the things owners swap out. The Gaggia North America listing is honest enough about this: what it names in the box is a plastic tamper and a coffee scoop.

Because the fittings are commercial 58mm, replacing them is easy and cheap. Many owners go to a 58.5mm tamper because the baskets run tight.
