Buying guide: how to choose a coffee machine

A coffee machine is chosen first on its water tank capacity and power, which shape daily comfort of use. Cup count and extraction pressure then refine the choice depending on how many people are served and the type of coffee sought.

What to check

Water tank capacity This criterion shows how much water the machine holds before needing a refill. Across recent market listings, values range from around 0.6 L for the most limited models to 2.5 L for the most generous, with a median near 1.2 L. A higher score means fewer refills, which matters for family use or repeated brewing throughout the day. A modest capacity suits occasional or single use, but quickly becomes limiting if several people rely on the machine. Market median: 1.2 L

Heating power Electrical power determines how fast the water heats and therefore how quickly the first cup is ready. Recorded benchmarks range from 700 W for the least powerful machines to 1,900 W for the fastest, with a median around 1,450 W. A high score signals quick heat up, useful in the morning or when brewing several cups in a row. Lower power does not prevent a good coffee, but it lengthens preparation time, especially with larger tanks. Market median: 1,450 W

Number of cups prepared This criterion measures how many cups the machine can prepare at once, a key point when several people are served together. Benchmarks range from one cup for individual models up to twelve cups for family machines, with a median of two cups. A higher score avoids restarting a brew for each serving. A model limited to one or two cups suits individual use well, but may fall short for families or entertaining. Market median: 2 cups

Extraction pressure The maximum pressure a machine can apply affects extraction and texture, notably for creamy preparations. Benchmarks sit between 15 bar for most models and up to 20 bar for the strongest performers, with the median staying at 15 bar. A higher score reflects deeper extraction capability, valued for strong coffee. This criterion matters most if the desired coffee style requires brewing under high pressure. Market median: 15 bar

Setup and everyday maintenance A coffee machine needs a stable surface, close to a power outlet and easy access to water if the tank is not simple to remove and refill. Regular descaling extends the appliance’s lifespan and preserves coffee flavour; how often depends on local water hardness. Cleaning the filter holder or steam wand after each use prevents residue build up. These simple habits are not reflected in the product score but shape how well the machine performs over time.

What you get for each budget

Under 130 €

At this price level, machines often show a more modest tank capacity and power, with a limited cup count, a sensible fit for individual or occasional use.

130 to 520 €

This range groups machines with a more balanced trade off between capacity, power and cup count, sometimes with higher extraction pressure.

Over 520 €

Beyond that, machines generally combine stronger scores across several criteria at once, notably higher capacity and power, suited to intensive or family use.
