2025-01-28

Making a latte isn’t as complicated as it seems. It’s all about combining a perfectly pulled shot of espresso with silky, velvety milk. Using a semi-automatic espresso machine not only gives you control over every step but also allows you to enjoy the process—especially when you start experimenting with latte art. Here’s a quick version for when you’re short on time, followed by detailed steps for those who want to go all in.

Quick Version: Latte in 5 Simple Steps

1. Prepare: Grind 18–20g of coffee beans and fill your milk pitcher halfway with milk.

2. Extract Espresso: Tamp the coffee grounds evenly, lock in the portafilter, and extract 30ml of espresso.

3. Steam Milk: Use the steam wand to froth the milk to 60–65°C, creating a smooth, silky texture.

4. Combine: Pour the milk into the espresso, starting with the liquid and finishing with the foam.

5. Finish: Swirl your milk pitcher and pour to create a simple latte art design, like a heart or leaf.

That’s it! If you want to dive into more detail, let’s go step by step.

Detailed Version: How to Make the Perfect Latte

1. Gather Your Ingredients and Tools

Before you start, make sure you have everything you need:

‧ Coffee beans: 18–20g of medium to dark roast beans work well for lattes.

‧ Milk: Use whole milk for better foam texture, or try oat milk designed for barista use.

‧ Tools: Semi-automatic espresso machine, tamper, milk pitcher, coffee scale, and a cup.

‧ Temperature goals: Brew water should be 90–96°C (195–205°F), and milk should be steamed to 60–65°C (140–150°F).

2. Preheat Your Machine and Tools

‧ Turn on your espresso machine and let it preheat for at least 10 minutes.

‧ Preheat your portafilter and cup by running hot water through them to ensure stable brewing temperature.

3. Pulling the Perfect Espresso Shot

1. Grind Your Coffee

‧ Grind your beans to a fine consistency, similar to granulated sugar.

‧ Measure 18–20g of grounds using a coffee scale for precision.

2. Tamp the Coffee Grounds

‧ Distribute the coffee grounds evenly in the portafilter.

‧ Use a tamper to apply firm, even pressure, ensuring the surface is flat.

3. Extract the Espresso

‧ Lock the portafilter into the machine and start brewing.

‧ Aim for a 25–30 second extraction that yields about 30ml of espresso.

‧ If it’s too fast or too slow, adjust the grind size or tamping pressure accordingly.

4. Steaming the Milk

1. Prepare the Milk

‧ Pour milk into your pitcher, filling it about halfway to allow room for frothing.

2. Purge the Steam Wand

‧ Turn on the steam wand briefly to purge any condensation and ensure strong, steady steam.

3. Froth the Milk

‧ Position the steam wand just below the surface of the milk to introduce air, creating a soft “hissing” sound.

‧ Once you’ve added enough air, submerge the wand slightly deeper to create a whirlpool effect, breaking down large bubbles and integrating the foam.

‧ Stop steaming when the milk reaches 60–65°C (140–150°F). The pitcher should feel hot to the touch but not burn your hand.

5. Combining Espresso and Milk

1. Tap and Swirl the Milk

‧ Gently tap the milk pitcher on the counter to pop any remaining bubbles, then swirl to mix the foam with the liquid milk.

2. Pour the Milk

‧ Start pouring from a higher position to mix the liquid milk with the espresso.

‧ As the cup fills, lower the pitcher and tilt it slightly to let the foam flow, creating a creamy surface.

‧ For latte art, practice simple designs like a heart or a leaf by controlling the pour speed and direction

Tips and Troubleshooting

‧ Espresso too bitter or weak? Adjust the grind size or tamping pressure.

‧ Milk foam too thick or thin? Adjust how much air you introduce and ensure the milk is spinning smoothly.

‧ Temperature issues? Use your hand to feel the milk pitcher; it should be hot but not scalding.
