Stainless group heads on an espresso machine with pale-handled portafilters locked in, two dark streams of espresso running into cups on the drip tray.
A commercial multi-group machine, shown because it makes the group head and portafilter easy to see. It is illustrative of the category, not a recommendation, and domestic machines are much smaller.

Brewing vessel

Espresso machine

Uses a pump or lever to force hot water through finely-ground, tamped coffee under pressure to produce espresso.

In short

An espresso machine heats water and pushes it through a compact bed of finely ground coffee at high pressure. That description fits a lever machine worked by hand and a one-touch machine that grinds, brews and froths milk without being touched. The words on the box say little; what matters is which jobs the machine does and which it leaves to you.

Sort machines by that question and they fall into four kinds. Each has its own page here with the detail. This page is for telling them apart.

Four kinds, sorted by who does the work

Widely documented

  • Manual lever — You create the pressure yourself with a lever, as well as grinding, dosing and tamping. The most involved and the most direct, with nothing electronic between you and the shot.
  • Semi-automatic — A pump makes the pressure. You grind, dose, tamp and decide when to stop the shot. This is the kind most home enthusiasts and most cafés use, and it needs a separate grinder.
  • Bean-to-cup — Grinds, doses, tamps and brews inside the machine at the press of a button, often with automatic milk as well. Convenience first, with limited room to adjust.
  • Pod or capsule — Brews from a sealed, pre-dosed capsule. Nothing to grind or measure, a narrow choice of coffee, and a higher cost per cup.

Working out which kind you are looking at

CoffeeHQ explanation

  1. Is there a portafilter?. A detachable handle with a metal basket that locks into the front means a manual or semi-automatic machine. If coffee goes in as beans at the top or as a capsule, it is one of the automatic kinds.
  2. Is there a grinder built in?. A bean hopper on a machine with a portafilter means a semi-automatic with an integrated grinder. A hopper and no portafilter means bean-to-cup.
  3. What stops the shot?. If you stop it, the machine is semi-automatic. If it stops itself at a programmed volume, it is often sold as automatic, though you still do the grinding and tamping.
  4. What does the basket look like?. A basket with one small exit hole underneath is pressurised, which is common on entry-level machines and changes how much the grind matters.

Sellers use these words loosely, and automatic in particular is applied to machines at both ends of the range. Check what the machine does, not what it is called.

What the price of the machine leaves out

CoffeeHQ explanation

A machine with a portafilter cannot make espresso on its own. It needs a grinder capable of grinding finely and adjusting in small steps, and that grinder matters at least as much to the result as the machine does. A capable machine paired with a poor grinder makes poor espresso; the reverse pairing usually does better.

Beyond the grinder there is a tamper, a scale accurate to a fraction of a gram, a milk jug if you steam milk, and cleaning supplies. None is expensive individually. Together with the grinder they are a real part of the cost, and the reason a bean-to-cup or capsule machine can be the more sensible purchase for someone who wants the drink and not the hobby.

What separates one machine from another

Tendency, not a guarantee

Among machines of the same kind, the differences that affect daily use are mostly about heat. A machine with one boiler brews and steams at different temperatures and makes you wait between the two. Machines with a heat exchanger or two boilers can do both at once. Electronic temperature control keeps the brew water steadier from shot to shot.

Steam power decides how easily milk can be textured. Warm-up time decides whether the machine suits a rushed morning. These features differ machine by machine and cannot be assumed from the category, which is why each is something to check in the specification of the model in front of you.

Common misunderstandings when buying

CoffeeHQ explanation

Expecting a higher pump pressure figure to mean better espresso

Usually because: Espresso is conventionally brewed at around nine bar. A larger number on the box describes what the pump can reach, not the pressure at the coffee.

Change first: Ignore the headline pressure figure when comparing machines.

What the pressure gauge is telling you

Assuming thick crema proves a good shot

Usually because: Pressurised baskets and capsules make foam mechanically, whatever the coffee underneath tastes like.

Change first: Judge by taste; treat crema as a clue at most.

Pressurised vs non-pressurised basket

Planning to use pre-ground coffee in a standard basket

Usually because: A standard basket relies on a grind matched to the machine, and pre-ground coffee cannot be adjusted.

Change first: Budget for a grinder, or choose a machine built around a pressurised basket.
