Finding an Espresso Machine: Six Questions Before You Buy

Most buying guides start with the machines. We start with your morning – because that's where the answer lives, not in the spec sheet.

Question 1: What Do You Actually Drink?

Not what you'd like to drink when guests are over. What you drink on an ordinary Tuesday.

• One to two espressos, black. A single boiler is enough. You save money, space, power, and heat-up time.
• One to two milk drinks a day. A heat exchanger takes the switching off your hands.
• Several drinks back to back, roasts that vary. Then a dual boiler is worth it.
• Filter coffee with the occasional espresso. You might not need a portafilter machine at all, just a good grinder and a hand filter.

What technically separates these machine types is covered in detail in Single Boiler, Heat Exchanger, or Dual Boiler. In short: a heat exchanger is not a dual boiler – that mix-up shows up in plenty of product descriptions and regularly leads people to the wrong machine.

Question 2: How Much Goes Into the Grinder?

This is the point where we most often talk people out of their original plan. If your budget is limited, the larger share belongs in the coffee grinder, not the machine.

The reason is simple: the machine can only extract what the grinder has prepared. Unevenly ground coffee creates channels in the puck – and water runs through those, no matter how stable the temperature is. A good grinder on a simple machine reliably beats the reverse combination.

Question 3: How Much Space Do You Actually Have?

Measure before you order:

• Height under the wall cabinet – including the clearance the water tank lid needs to open.
• Counter depth, including the gap to the wall for hoses and plugs.
• Width next to the grinder, the knock box, and the scale.

More purchases fail on this number than on budget. And it can't be negotiated afterward.

Question 4: What's Your Water Like?

Limescale is the most common reason machines end up in our workshop. Depending on the region, Swiss tap water is hard enough that treatment isn't optional. It costs little, extends the machine's life considerably – and, as a side effect, changes the taste, because water is the largest component of your coffee.

A direct plumbed connection, on the other hand, is rarely necessary at home. It's worth it if you pull a lot of shots or don't want to keep refilling the tank.

Question 5: How Much Time Do You Have in the Morning?

Machines with an E61 brew group need their time. As rough benchmarks from the technical literature: 20 to 25 minutes until ready to use, 30 to 40 minutes until truly stable. Single boilers are faster, thermoblock machines fastest of all.

If you don't have half an hour of lead time in the morning, the solution is a timer or an auto-on switch – not a different machine type. That's cheaper than any purchasing decision.

Question 6: What Is the Machine Worth to You – and for What?

Up to a certain point, you're buying taste: temperature stability and steam power make a noticeable difference. Beyond that, you're buying build quality, parts availability, looks, and the enjoyment of the machine itself. Those are good reasons – but they're not taste reasons, and it helps to be honest with yourself about that.

What we won't do: tell you which machine is "the best." There isn't one. There's one that fits your morning.

Frequently Asked Questions About Buying a Machine

What's the most important question when buying a machine?

What you actually drink. If you drink almost nothing but black espresso, you don't need a big steam boiler. If you make three milk drinks a day, choosing a single boiler saves money in the wrong place. Everything else – brand, looks, features – comes after that.

How much should I budget for the grinder?

More than most people think. If your budget is limited, the larger share goes to the grinder, not the machine. A good grinder on a simple machine delivers better espresso than the reverse – that hasn't changed.

Which machine type should I choose?

Single boiler for mostly black espresso, heat exchanger for daily milk drinks, dual boiler for multiple drinks back to back and degree-precise temperature control. Note: a heat exchanger is not a dual boiler, but a heat-exchanger machine.

How much space do I need?

Before buying, measure the height under the wall cabinet and the depth of the counter – including room for the water tank lid, which often opens upward. This measurement trips people up more often than budget does.

Do I need a direct plumbed water connection?

Usually not at home. It's worth it if you pull a lot of shots or don't want to keep refilling the tank. Water treatment matters more: limescale is the most common reason machines come to our workshop.

How long does heating up take?

It depends on the type and the brew group. Single boilers are fastest; machines with an E61 brew group need, as a rough benchmark, 20 to 25 minutes to become ready to use and 30 to 40 minutes to become truly stable. A timer solves this more elegantly than switching machine types.

Does a more expensive machine taste better?

Only up to a point. Temperature stability and steam power make a noticeable difference. Beyond a certain level, you're paying for build quality, parts availability, and looks – all legitimate reasons, but not taste reasons.

What about used machines?

Often a good idea, if the machine's history and maintenance record are clear. Watch out for limescale, gaskets, and parts availability. Brands with long-term parts support have a clear advantage here.

How much maintenance does a portafilter machine need?

Rinse it daily, backflush regularly, keep an eye on the gaskets, descale depending on water hardness. That's manageable – but it's not zero, and if you ignore it, you'll notice it in the taste before you notice it on the machine.

Can I try machines at your store?

Yes. In Bern at Gerberngasse 44 and in Zurich at Hagenholzstrasse 50b. For a thorough comparison, it's worth booking a consultation – that way, everything is set up and ready.
