Gaggia Classic GT

Prosumer Precision. Italian Heritage.

Gaggia’s story began in 1938, when Achille Gaggia changed espresso brewing forever.

The Classic GT takes that heritage into a much more advanced category.

This isn’t simply a Classic with a few additional features. The GT is built around a dual-boiler architecture, giving the brew circuit and steam circuit their own dedicated boilers and PID temperature control.

That makes a meaningful difference to the way the machine behaves.

You can concentrate on extraction without waiting for the machine to switch between brewing and steaming, while the adjustable pre-infusion and OPV give you considerably more control over how your espresso is extracted.

For the home barista who has moved beyond simply pressing a button and wants to understand and control the variables behind the shot, the Classic GT is a serious step forward.

Why We Stock It

We look at espresso equipment differently from simply asking how many features a machine has.

The question is whether those features give you better control over the coffee.

The Classic GT does.

The dual PID-controlled boilers provide independent temperature control for brewing and steam. The adjustable OPV lets you set your brewing pressure externally, while the selectable pre-infusion gives you another variable to work with when dialling in different coffees.

Add the 58mm commercial-style brew group and a proper steam wand, and you have a machine that gives an experienced home barista plenty of room to refine their technique.

It is the kind of machine you can grow into rather than quickly grow out of.

Dual Boiler. Independent Control.

One of the biggest advantages of the Classic GT is its dual-boiler design.

Brew Boiler

The 0.1L brew boiler is independently PID controlled, providing stable brewing temperature for espresso extraction.

Steam Boiler

The larger 0.9L steam boiler is separately PID controlled, giving you dedicated steam capacity without relying on the brew boiler to perform both jobs.

This separation makes the machine much more practical when preparing espresso and milk drinks at the same time.

Control Your Extraction

Adjustable Pre-Infusion

Different coffees can respond very differently to the same recipe.

The Classic GT gives you the ability to use automatic or manual pre-infusion, allowing you to experiment with how water initially enters the coffee puck before full brewing pressure is applied.

This is particularly useful when working with different roast levels and coffees that respond differently to pressure and flow.

Externally Adjustable OPV

The Over Pressure Valve (OPV) can be adjusted externally, allowing you to control the machine’s brewing pressure without opening the housing.

That’s a valuable feature for anyone who takes espresso dialling-in seriously.

Rather than accepting a fixed factory pressure, you can adjust the machine around your preferred brewing approach.

Features

Dual PID-Controlled Boilers

Independent temperature control for the brew and steam boilers provides greater stability and allows you to brew and steam without the compromises associated with a single-boiler system.

58mm Brass Brew Group

The 58mm brass brew group uses a commercial-standard format, giving you access to a huge range of aftermarket baskets, tampers and other espresso accessories.

TFT Touch Display

The 2.4-inch capacitive TFT display provides an intuitive interface for controlling the machine and viewing brewing information.

Integrated Shot Timer

The built-in shot timer gives you immediate feedback during extraction, making it easier to repeat recipes and identify changes when dialling in coffee.

Automatic & Manual Pre-Infusion

Choose between automatic operation or manually controlled pre-infusion depending on the coffee and recipe you’re working with.

Volumetric Brewing

Programmable volumetric brewing allows you to set repeatable beverage volumes while still retaining manual control when you want to take over.

Wake-Up Programming

Program the machine to warm up ahead of your normal brewing routine, so it’s ready when you are.

Professional Steam Wand

The stainless steel steam wand is designed for proper milk texturing, giving you the control required to produce smooth microfoam for flat whites, cappuccinos and latte art.

Dedicated Hot Water Outlet

A separate hot-water dispenser keeps hot-water preparation independent from the steam wand and brewing group.

Stainless Steel Construction

The brushed stainless steel housing provides a durable exterior while giving the machine the clean, understated appearance associated with Gaggia’s commercial heritage.

Who Is It For?

The Gaggia Classic GT is particularly suited to:

• Experienced home baristas
• Specialty coffee enthusiasts
• Espresso enthusiasts
• People upgrading from a single-boiler machine
• Home users who regularly prepare milk-based drinks
• Anyone wanting prosumer-level control in a compact machine

Consider the Classic GT if you want:

Temperature control
Dual PID boilers give you much more control over brewing and steaming temperatures.

Pressure control
The externally adjustable OPV allows you to tune brewing pressure.

Extraction control
Manual and automatic pre-infusion provide another tool for dialling in coffee.

A commercial ecosystem
The 58mm group works with a huge range of professional and aftermarket accessories.

Shipping Information

I would keep this separate from the machine specifications in WooCommerce.

I can confirm the 18kg machine weight and 260 × 425 × 417mm product dimensions from the information supplied, but I would not use these as shipping figures.

For the shipping fields, I recommend using the actual manufacturer carton dimensions and gross packaged weight rather than estimating them.

Aura Bean Brewing Tip

The Classic GT gives you more control than most home machines, but more control doesn’t automatically mean better espresso.

Start with a repeatable recipe. Keep your dose, yield and grind consistent, then change one variable at a time.

The PID, OPV and pre-infusion controls become particularly useful once you’ve established a baseline. That’s when you can start exploring how different coffees respond to changes in temperature, pressure and pre-infusion rather than changing everything at once.

The Aura Bean Difference

The Classic GT is interesting to us because it gives the home barista access to the variables that actually matter.

Temperature. Pressure. Pre-infusion. Dose. Yield.

Those are the tools that allow you to understand your coffee rather than simply operate a machine.

The result is a machine that can sit comfortably between a traditional home espresso machine and a much larger prosumer setup.

If you’re serious about learning espresso and want equipment that gives you room to keep improving, the Classic GT is a machine worth considering.
