A latte is a double espresso lengthened with silky steamed milk. Getting it right means nailing your espresso shot and steaming milk to microfoam consistency — velvety, glossy, and pourable. Here is the complete method.
A machine with a steam wand is essential. Even entry-level machines with a Panarello or Aeroccino wand can produce acceptable milk texture. A proper single-hole steam tip on a semi-automatic gives the most control.
Fresh-ground espresso is the foundation. A consistent burr grinder ensures even extraction. Blade grinders and pre-ground coffee will produce a weak or sour espresso base that no amount of milk can save.
A 350-500ml stainless steel milk pitcher with a pointed spout for pouring. The stainless steel lets you feel the temperature through the jug. A pitcher thermometer is recommended until you can judge temperature reliably by touch.
A 240-300ml ceramic cup is standard. Pre-warm it by filling with hot water from the machine and discarding before pulling your shot. A warm cup prevents the espresso from cooling too quickly while you steam milk.
Dose 18-20g, grind fine, tamp level, and extract a 36-40g double espresso in 25-30 seconds. Pour it into your pre-warmed cup. The espresso should show crema and be extracted evenly — if it pours too fast or too slow, adjust your grind before adding milk.
Fill a 350ml pitcher to just below the spout with cold whole milk. Cold milk gives you more time to texture it before it reaches serving temperature. Never overfill — you need headroom for the milk to expand as it aerates.
Open the steam valve briefly to purge condensed water from the wand. This prevents watery milk. Close it, submerge the wand tip just below the milk surface, then open fully. Position the tip slightly off-centre to create a vortex.
Lower the pitcher slightly for 2-3 seconds to introduce air — you will hear a soft tearing or hissing sound. Then raise the pitcher to submerge the tip and spin the milk without adding more air. You are incorporating the bubbles into a uniform texture.
Continue steaming until the pitcher bottom is too hot to hold comfortably with a flat palm — approximately 65 degrees Celsius. Remove the wand, purge it again, and wipe clean immediately. Tap the pitcher on the bench and swirl vigorously to pop any large surface bubbles.
Swirl the pitcher once more before pouring. Pour the milk from height into the centre of the espresso first to integrate the layers, then lower the pitcher close to the cup surface and pour the final stream to leave a small white circle or simple pattern on top. Serve immediately.
The espresso is getting lost in the milk and the drink tastes of hot milk with a coffee hint.
The milk tastes cooked, flat, or slightly sulphurous — the natural sweetness is gone.
The milk is bubbly and thick on top but watery underneath, or it all runs out at once without control.
