Lattes and espresso drinks at home

Milk drinks have two parts

Lattes, cappuccinos and flat whites are all strong coffee combined with heated milk. What changes from one to the next is the amount of coffee and milk and how thick the foam on top is. So at home you only need to learn two things, pulling strong coffee consistently and heating milk properly, and you can adapt that to most of the menu. You do not need an expensive machine to make a cup close to what a cafe serves. The names and differences of each drink are covered in detail in the menu terms guide.

With a machine: espresso starting values

Espresso is coffee made by forcing hot water through finely ground coffee under high pressure, giving a strong drink in a short time. Every machine differs, but these numbers are a common starting point. If it tastes sour, grind finer; if bitter, grind coarser, just as with pour-over. For the first few days, keep the beans, dose and yield fixed and change only the grind; that is the fastest way in.

• Dose about 18 grams for a double shot
• Aim for about twice that weight in the cup, around 36 grams
• Take around 25 to 30 seconds
• Fill the basket evenly and tamp it level

Strong coffee without a machine

Even without an espresso machine you can make coffee strong enough not to vanish under milk. It is not exactly espresso, but once milk goes in the difference shrinks a lot.

• Stovetop pot: brews strong coffee on the burner using steam pressure, heavy and intense
• Concentrated pour-over: use about half the usual water to make a strong brew
• Instant coffee: dissolve it strong in a little hot water and mix with milk

How hot to heat the milk

Milk tastes sweetest heated to about 60 to 65°C. Past 70°C the sweetness drops, a cooked or slightly off smell appears, and the foam collapses quickly. When the jug becomes too hot to hold comfortably for long, you are about there; a thermometer is far more accurate. Regular dairy milk has enough fat and protein to foam smoothly. Plant-based drinks vary by product and may not foam well, so versions labeled for baristas are easier to work with.

Frothing milk without a steamer

No steam wand is no problem. The goal is not big bubbles but a glossy surface with fine foam.

• Heat the milk in a pot or microwave to 60 to 65°C
• Pour it into a French press and pump the plunger quickly, or use a handheld frother
• Tap the container on the counter to pop large bubbles
• Swirl so the milk and foam do not separate, then pour over the coffee

Iced drinks and sweetness

For an iced latte it is easiest to fill the glass with ice and cold milk first, then pour the strong coffee on top. Hot coffee poured straight onto ice melts a lot of it and waters the drink down, so brew a little stronger than usual. If you want sweetness, dissolve equal amounts of sugar and water over heat to make a syrup that mixes easily into cold drinks. You can also stir flavors such as vanilla into that syrup. Keep the syrup in a clean bottle in the fridge and use it up soon.

Common mistakes

The most common mistake is overheating the milk. Hotter seems better, but the sweetness disappears and the foam turns coarse. Coffee that is too weak leaves only the taste of milk, so coffee for milk drinks needs to be stronger than ordinary coffee. Too much foam makes each sip feel like a mouthful of air, and foamed milk left sitting separates into milk and foam. Pour frothed milk right away.

Safety and hygiene

Steam wands and stovetop pots both involve hot steam and pressure. Wipe the steam wand with a damp cloth right after use and purge it briefly so milk does not dry and clog it. Fill a stovetop pot only up to the safety valve, do not pack the grounds down, and heat it over medium-low. A blocked pot on high heat can build up dangerous pressure. Avoid reheating milk that has already been heated or leaving it out at room temperature for long, and if milk drinks upset your stomach, try lactose-reduced milk or a different drink.
