How to Make a Classic Latte with an Espresso Machine

Making a great latte isn’t just about pouring steamed milk into espresso — it’s about controlling every variable, from cup warmth to milk texture. Whether you're aiming for a classic version or experimenting with syrups, nailing the steps ensures balanced flavour and velvety microfoam every time.

To make a standard latte, pull a 30ml (1oz) espresso shot over 20–25 seconds, then add 150–180ml of textured milk heated to below 90°C. Steam the milk to create a smooth microfoam layer, pour with control, and finish with optional syrup — usually 6–8ml for chocolate or flavoured versions.

What You Need to Make a Latte

You’ll need an espresso machine with a steam wand, freshly ground dark roast coffee beans, milk, and optionally, flavoured syrup like chocolate or vanilla. The typical dose is around 7ml (about 0.25oz) of finely ground coffee for a single shot. Use a cup — preferably a large mug — that holds at least 200ml.

Step 1: Preheat Your Cup

Start by warming your cup to maintain espresso and milk temperature. Pour hot water into the mug, let it sit for 30 seconds, then discard the water. Alternatively, place the cup on the espresso machine’s cup warming tray while you prepare the shot — the residual heat will bring it to the ideal serving temperature.

Step 2: Pull the Espresso Shot

Grind dark roasted coffee beans to a fine espresso-appropriate setting — roughly the texture of powdered sugar. Dose approximately 7ml (or about 0.25oz) of coffee into the portafilter, then tamp it evenly using a distribution tool and a firm press. Lock the portafilter into the machine and pull a 30ml shot over 20–25 seconds. For best results, position the portafilter spout close to the cup’s inner wall to help develop a rich, stable crema.

Step 3: Add Flavour (Optional)

If you’re making a flavoured latte — such as chocolate or vanilla — stir in 6–8ml of syrup directly into the espresso before adding milk. Chocolate syrup is common for a mocha-like profile, while vanilla works well for a creamy twist. Adjust to taste, but keep additions modest to preserve balance.

Step 4: Steam the Milk

Pour cold milk (whole milk preferred for texture) into a steaming pitcher. Position the steam wand just below the milk surface to create a whirlpool, introducing air to form microfoam. Once the volume increases slightly, submerge the wand deeper to heat the milk. Aim for a final temperature between 65–90°C — avoid going over 90°C to prevent scalding and ruining the foam structure.

Step 5: Texture and Texture Only

After steaming, tap the pitcher lightly on the counter to remove larger bubbles, then swirl the milk to integrate the foam with the liquid beneath. The ideal milk texture should be glossy and smooth, with a thin layer of microfoam on top for pouring.

Step 6: Pour the Latte

Pour the espresso (with syrup, if used) into your warmed cup. Hold back the foam with a spoon, then gently pour the steamed milk into the centre of the espresso. As the cup fills, gradually lift the spoon to allow a small amount of microfoam to float on top. For latte art, control the flow and angle of your pour.

Key Ratios and Temperatures

• Espresso: 30ml (1oz), extracted in 20–25 seconds
• Coffee dose: ~7ml (0.25oz) finely ground coffee
• Milk: 150–180ml total, textured not frothed
• Milk temp: 65–90°C (do not exceed 90°C)
• Syrup (optional): 6–8ml for flavour

Frequently Asked Questions

How much coffee do I use for a single latte shot?

Use around 7ml (approximately 0.25oz) of finely ground dark roast coffee for a standard single espresso shot. This yields roughly 30ml of extracted espresso used in a classic latte.

What’s the ideal milk temperature for a latte?

The optimal milk temperature is between 65–90°C. Going over 90°C can cause the milk to scorch, destroying the microfoam structure and creating a burnt flavour.

Do I need to use syrup in a latte?

No, syrup is optional. Classic lattes are made with just espresso and steamed milk. Flavoured syrups like chocolate or vanilla are added only if you’re making flavoured versions such as a mocha or vanilla latte.

How long should I pull the espresso shot?

Aim for a 30ml shot pulled over 20–25 seconds. This ensures proper extraction and crema development, crucial for flavour balance in the final latte.

Can I use any milk for steaming?

Whole milk is ideal for its fat content and ability to create stable microfoam. You can use skim or plant-based milks, but the texture and foam quality may differ.

What grind size is right for espresso in a latte?

Use a fine grind size, similar to powdered sugar. This is necessary to achieve the 20–25 second extraction window for a proper espresso shot with rich body and crema.
