What is the Breville Infuser BES840XL?
A semi-automatic espresso machine with the shot electronics of a more expensive one and no grinder attached.
Breville publishes 1650 watts, a 1.7 litre tank, a stainless steel body, 7.9kg and a one year warranty. The controls are the interesting part: digital PID temperature control adjustable in two degree steps, low pressure pre-infusion, volumetric control over how much goes in the cup, and an auto purge that clears heat out of the system after steaming so the next shot starts at the right temperature.
There is no grinder. That is the machine's entire argument.
Why leaving the grinder out is a feature
The grinder is the part of an espresso setup most worth upgrading, and the part hardest to upgrade when it is bolted inside the machine.
A built-in grinder is a convenience and a ceiling. When you outgrow it, the only way past is a new machine or a second grinder sitting beside the one you already paid for. Buying the machine and the grinder separately costs more attention up front and leaves both halves replaceable.
So this is the machine for somebody who already owns a grinder they like, or who intends to spend properly on one. Against the Barista Express, you get the same pre-infusion and a finer PID adjustment, and you supply the grind yourself.
Two degree steps and volumetric shots
Adjustable temperature is what turns a machine into something you can dial in.
PID that simply holds a fixed point is already better than a thermostat. PID you can move in two degree steps lets you match the machine to the coffee: lighter roasts generally want it hotter, darker ones cooler, and being able to make that change is the difference between adapting to a bag and enduring it.
Volumetric control does the same job for quantity. Set the volume once and the machine stops there, so a shot is repeatable without watching a scale. Neither feature is exotic. Both are unusual on a machine with no grinder in the price.
Breville Infuser vs Gaggia Classic Evo Pro
Two machines for somebody who owns a grinder, arguing about where the money should go.
The Gaggia Classic Evo Pro spends it on fittings: a 58mm commercial portafilter, a three way solenoid valve, a steel body made in Italy. The Infuser spends it on electronics: adjustable PID, volumetric shots, auto purge.
The Gaggia is the machine you keep and modify. The Infuser is the machine that makes a good shot with less of you involved. Gaggia publishes 9 bar and 58mm; Breville publishes the temperature control. Both are telling you what they think matters.
Is the Breville Infuser worth it?
It is worth it precisely when you have a grinder and do not want to pay for another.
PID with two degree adjustment, pre-infusion, volumetric control and a 1.7 litre tank is a serious specification, and every part of it is published rather than implied. The one year warranty is the same short term as the Barista Express carries.
Bought without a grinder, though, it makes nothing. That is not a criticism of the machine, it is the condition of the purchase, and the most common way people are disappointed by a good espresso machine.
Who should buy the Breville Infuser (and who should not)
Buy it if there is already a burr grinder on your worktop.
It suits somebody upgrading a machine rather than starting a setup, and anybody who wants to tune brew temperature to the bag rather than accept a fixed figure. The 1.7 litre tank also suits a household pulling several drinks in a morning.
Do not buy it as a first purchase unless a grinder is in the same budget. Do not buy it if you want the milk automated. And if you would rather not think about temperature at all, a super-automatic such as the Philips 4300 LatteGo removes the question entirely.
Frequently Asked Questions
Does the Breville Infuser have a built-in grinder?
No, and that is deliberate. It is aimed at people who already own a grinder or intend to buy one separately. The Barista Express is the same maker's machine with a grinder included.
Can you adjust the brew temperature on the Infuser?
Yes. Breville publishes digital PID temperature control adjustable in two degree steps, which lets you run lighter roasts hotter and darker ones cooler.
What is auto purge on the Breville Infuser?
After steaming milk the system is hotter than brewing wants. Auto purge clears that heat automatically so the following shot extracts at the right temperature rather than scorched.
How big is the Infuser's water tank?
1.7 litres, which is larger than most machines of this size carry and means fewer refills across a morning.
