The short answer
Buy the Infuser if you already own a grinder you like and want PID temperature control with a 61 oz tank for the least money. Do not buy it for speed - the ThermoJet machines heat in three seconds and this one does not - and do not buy it expecting help with milk, because the wand is entirely manual.
What the specification actually says
Four things define this machine: a 54 mm stainless portafilter with commercial-style spouts, a 1650 W thermocoil under electronic PID control, a 61 fl oz / 1.8 L removable filtered tank, and low-pressure pre-infusion before full extraction pressure.
PID is the one to pay attention to. A thermostat switches a heater on and off around a target, so brew temperature oscillates; a PID controller predicts and trims, so it settles. Shot to shot, that is the difference between a repeatable extraction and a moving target - which is why how to dial in espresso is a shorter job on a PID machine.
The tank is the specification nobody shops on and everybody lives with. At 1.8 L the Infuser holds roughly three times what the compact machines do, which in practice means filling it twice a week rather than every other day.
Where it sits in Breville's own range
Breville's line splits on two questions: does it grind, and how fast does it heat. The Bambino family answers 'no' and 'three seconds'. The Barista family answers 'yes' and 'fast enough'. The Infuser answers 'no' and 'slower than either'.
In exchange it gets the biggest tank in the non-grinding half of the range and PID control that the entry machines in the wider market often lack. It is the choice for someone whose grinder problem is already solved.
It is also the oldest design here, and it gets the least attention from Breville's marketing. Owners report that as a feature: the machine is well understood, widely serviced and cheap to keep running.
Where it stops
Heat-up. Thermocoil heating takes meaningfully longer than ThermoJet. If your morning has no spare minute, that matters more than any specification on the box.
Milk. The wand is manual with no automation of any kind. That is what an enthusiast wants and what a household of four at 7 a.m. usually does not.
54 mm. The Breville standard is 54 mm rather than the 58 mm used by commercial machines and by the Gaggia. Accessories exist in both sizes, but the 58 mm world is larger - see Gaggia Classic Pro vs De'Longhi Dedica for what portafilter size costs you later.

1. The machine reviewed
Breville Infuser
Mid tier · A grinder-less 54 mm machine with PID and a larger tank than the Bambino line.
PID temperature control and a 1.8 L tank at a grinder-less price.
The Infuser is a 54 mm machine with a 1650 W thermocoil under electronic PID control. PID is the specification that separates a machine holding a steady brew temperature from one whose thermostat swings either side of it, and at this price it is not a given - the Gaggia Classic Evo Pro ships without it.
Its water tank is 61 fl oz / 1.8 L, removable and filtered. That is roughly three times the working volume of the compact machines, which matters more than it sounds: refilling a small tank mid-session is the most common daily annoyance owners report on the Bambino line.
Extraction starts with low-pressure pre-infusion, the same approach Breville uses across the range. It wets the puck gently before full pressure arrives, which reduces channeling on a slightly uneven tamp.
Auto-purge is the feature owners mention most. After steaming, the machine resets the thermocoil to brew temperature by itself rather than making you flush and guess.
It heats more slowly than the ThermoJet machines - seconds against the Bambino's three - and the steam wand is entirely manual. Both are trade-offs made deliberately in favor of the tank and the PID.
Specification
- Portafilter
- 54 mm stainless, commercial-style spouts
- Heating
- 1650 W thermocoil with electronic PID
- Water tank
- 61 fl oz / 1.8 L, removable, filtered
- Extraction
- Low-pressure pre-infusion
What it does well
- PID plus a big tank at a grinder-less price
- Auto-purge resets brew temperature after steaming
- Pairs well with a serious standalone grinder
Where it gives ground
- Slower to heat than the ThermoJet machines
- Older design; the Bambino line gets more attention
- Manual steam wand only
Skip it if
Skip it if you want the machine on your counter to do everything. There is no grinder, no automatic milk, and no shortcut.
2. If the milk is the problem
Breville Bambino Plus
Entry tier · The Bambino with automatic milk texturing added.
Three-second heat-up and automatic milk texturing in a narrower case.
The Bambino Plus uses ThermoJet heating - ready in three seconds - and textures milk automatically to a set temperature and foam level.
For a household where the espresso is mostly a base for cappuccinos, that automation is worth more day to day than the Infuser's bigger tank.
Its footprint is 11.9 x 7.4 x 14.3 in and its milk jug holds 16 fl oz, so it suits a narrow counter with a grinder beside it.
What you give up is the tank size and the manual control of the wand: auto-steam is a fixed result rather than something you learn to shape.
It also has no grinder, so the real budget here is still machine plus grinder - see best grinders for Breville espresso machines.
Specification
- Portafilter
- 54 mm stainless, 18 g dose
- Heating
- ThermoJet, ready in 3 seconds
- Pump
- 15 bar Italian pump, 9 bar extraction
- Milk
- Automatic texturing, 16 fl oz / 480 ml jug
- Footprint
- 11.9 x 7.4 x 14.3 in
What it does well
- Automatic milk texturing gets a usable microfoam without practice
- Same three-second heat-up as the standard Bambino
- Fits a narrow counter with a grinder beside it
Where it gives ground
- You are paying for the milk automation, not better espresso
- Still no grinder
- Auto-steam removes the control an enthusiast eventually wants
Skip it if
Skip it if you want to learn to texture milk yourself. The automation is the product.
3. If you have no grinder at all
Breville Barista Express
Mid tier · The all-in-one: espresso machine with a conical burr grinder built into the case.
The same 54 mm platform with a conical burr grinder built into the case.
The Barista Express puts a conical burr grinder with 16 settings inside the machine, with PID-controlled thermocoil heating at 200 F.
For someone starting from nothing, that removes the second purchase entirely, and it is why this machine has the largest owner base in home espresso.
Sixteen grind settings is coarse resolution for espresso, and the built-in grinder is the component you cannot upgrade later. That is the ceiling the whole machine runs into.
Its footprint is 15.9 x 13.1 x 12.4 in - considerably wider than an Infuser and a separate grinder placed side by side is not, which surprises people.
If you already own a good grinder, you are buying a second, weaker one - which is precisely the case for the Infuser instead.
Specification
- Portafilter
- 54 mm stainless
- Grinder
- Integrated conical burr, 16 settings
- Heating
- Thermocoil, 200 F, PID controlled
- Footprint
- 15.9 x 13.1 x 12.4 in
What it does well
- One box, one price, one plug - nothing else to buy
- PID temperature control at this level is not a given
- Enormous owner base, so parts and answers are easy to find
Where it gives ground
- 16 grind settings is coarse resolution for espresso dialing
- The built-in grinder is the weakest component and cannot be upgraded
- Wide footprint for a single-boiler machine
Skip it if
Skip it if you own a grinder worth keeping. You would be paying for a lesser one built into the case.

Scroll the table sideways to see every column.
Who should buy it
- People who already own a serious grinder and want temperature control rather than a second grinder.
- Households that pull several drinks in a session, where a 1.8 L tank stops the session being about refilling.
- Anyone who wants to learn milk by hand, because nothing here does it for you.
Who should not
- Anyone starting from zero - the Barista Express includes the grinder you would otherwise buy.
- Anyone in a hurry, where three-second heat-up is the feature that gets used every single morning.
- Cappuccino households, who will be happier with automatic texturing.
