Gaggia Classic Pro Espresso Machine Review: Pros, Cons and Comparisons
A metal, commercial-portafilter espresso machine for $449 — with no PID and a following that will tell you to add one.
Buy it if
- You want the 58 mm commercial standard from day one
- You are willing to learn temperature surfing or add a PID
- You want a machine you can modify rather than replace
Skip it if
- You want it to work perfectly out of the box
- You brew light roasts, which need stable temperature
- Modifying kitchen equipment does not appeal to you
The Classic Pro is the cheapest way into the 58 mm commercial ecosystem, in a metal body, with a modification community that has been documenting upgrades for twenty years. What it does not have is temperature control, and that single omission defines both its weakness and its appeal.
Metal and 58 mm, or PID?
At this price you can have a commercial portafilter in a metal body, or you can have stable brew temperature. Not both. That is the entire decision between the two machines people cross-shop here.

Where the 8.5 comes from
Five criteria. It is the only machine here that gets better after you buy it, and the only one that needs to.
Specifications
What it does well, and what it does not
The 58 mm group is the thing to understand. It is the commercial standard, which means every basket, tamper, distribution tool and bottomless portafilter on the market fits it. Machines with 54 mm or 51 mm groups cut you off from most of that, and it is a limitation you feel more the longer you own the machine. The Classic Pro is the cheapest way to be on the right side of it.
The missing PID is equally decisive in the other direction. A simple thermostat overshoots and then drifts down, so brew temperature depends on exactly when in that cycle you pull. Experienced owners manage it by timing — temperature surfing — and most eventually fit an aftermarket controller. Both work. Neither is something a $589 Breville asks of you.
What we like
- 58 mm commercial portafilter opens the entire aftermarket
- Metal body at a price where competitors use plastic
- Non-pressurised baskets included, not as an upgrade
- Twenty years of documented modifications
What to know
- No PID — brew temperature swings by several degrees
- Requires temperature surfing or an aftermarket controller
- Steam wand is capable but slow to recover
- Heat-up time is not published
What else to consider

A 58 mm machine deserves a grinder that can dial in. The Encore cannot; this can.Check price

How we scored it
This review is editorially researched. We worked from Gaggia’s published specifications, the owner record on Amazon, the long-running modification documentation around this machine, and comparison against machines in the same bracket, with price and availability confirmed on 12 August 2026. We have not run this machine ourselves and do not claim to have. Gaggia publishes no heat-up figure and the spec table says so.

The cheapest way onto the right side of 58 mm
For $449 you get a metal machine with the commercial portafilter standard and two decades of documented upgrades behind it. You also get a machine that needs work before it performs consistently. If that sounds like a project you would enjoy, nothing else at this price comes close. If it sounds like a chore, the Breville Infuser costs $141 more and simply works.
