Espresso at home: what to know about a La Pavoni lever machine

A traditional espresso machine at home follows a different logic from capsules or a bean-to-cup automatic. Here you are responsible for the grind, the dose, the tamp and the extraction time, which is exactly why the result can beat a coffee shop — or fall well short of it if the basics are skipped. This is what is worth understanding before buying rather than after.

The machine is half the kit

The other half is the grinder. On a traditional machine the taste shifts with the smallest change in grind, and no machine, however expensive, rescues unevenly ground coffee. If the budget is limited, a simpler machine with a decent burr grinder beats the opposite arrangement. Add to the list a tamper matched to the basket diameter, a scale that reads to a tenth of a gram, and a milk jug if cappuccino is on the plan.

Warm-up decides the shot

A cold group and a cold portafilter take temperature out of the water, and the first shot comes out sour even with the grind set correctly. So the machine is given time to heat, and the portafilter stays locked in the group. Wipe it dry before dosing: moisture in the basket changes how the puck behaves.

Water is the other factor that gets underestimated. Water that is too hard leaves scale in the boiler and a flat taste in the cup; water that is too soft makes the coffee sharp and hollow. The simplest answer is filtered water of drinking quality and descaling on the schedule in your machine's manual. Get into the habit of counting cups rather than months: a machine making two coffees every morning needs attention far sooner than one switched on at weekends. And keep the beans in a closed jar away from the hob, because freshness affects the cup more than any setting does.

What to adjust, and in what order

• the dose: weigh the coffee and keep the same weight from shot to shot;
• the grind: one change at a time, or you will never know what did it;
• distribution: break up the grounds in the basket before tamping so no channels form;
• the tamp: even pressure and a level puck matter more than force;
• yield and time: record the weight in the cup and the seconds, or there is nothing to compare;

Keeping it clean

After every shot knock out the puck, rinse the basket and wipe the group gasket. Once a week take the basket out and soak the portafilter in a coffee-oil cleaner: those oils are what turns the aftertaste bitter over time. Wipe the steam wand immediately after texturing milk, before it dries, and purge it so no milk is left inside. Every few months check the group gasket as well: hardened rubber starts letting water past the edge of the portafilter, and that shows long before an actual leak does.

A traditional machine rewards attention and punishes haste. If the process itself appeals to you, it is a fine choice and it will teach you more about coffee than any automatic. If what you want is a button in the morning and no ritual, an automatic machine is the honest answer, and we are happy to suggest where to start.
