How to Make a Cortado at Home: A Step-by-Step Guide for the Perfect Milk Coffee

If you’re a coffee lover who enjoys the rich, bold flavour of espresso but also appreciates a touch of creamy milk, the cortado might be your new favourite drink. Originating from Spain, this small but mighty beverage has gained a loyal following among home baristas and café enthusiasts alike. In this guide, we’ll show you how to make a perfect cortado at home, covering everything from the ideal espresso shot to the right milk texture.

The cortado is often confused with other milk coffees like the flat white or latte, but it has a distinct character. With a 1:1 ratio of espresso to steamed milk, it delivers a balanced, velvety texture without overwhelming the coffee’s natural flavours. Whether you’re new to home brewing or a seasoned pro, mastering the cortado is a rewarding skill that elevates your daily coffee ritual.

What is a Cortado?

A cortado is a Spanish coffee drink made with equal parts espresso and steamed milk. The name comes from the Spanish verb 'cortar,' meaning 'to cut,' as the milk cuts through the intensity of the espresso. Typically served in a small glass (around 150–200 ml), it’s a drink that prioritises coffee flavour over milk volume. Unlike a latte, which has a thick layer of foam, the cortado uses microfoam that is thin and silky, blending seamlessly with the espresso.

For home baristas, the cortado is an excellent choice because it requires minimal equipment—just a good espresso machine or a strong moka pot, fresh coffee beans, and a milk frother. It’s also a fantastic way to showcase high-quality beans, especially single-origin or washed espressos, whose nuanced notes can shine through the milk.

• Cortado vs Flat White: A flat white uses a double shot of espresso with a thin layer of microfoam, but the milk-to-coffee ratio is higher (around 1:2). The cortado is more balanced at 1:1, making it stronger in coffee flavour.
• Cortado vs Latte: A latte has a much higher milk-to-coffee ratio (1:3 or more) and a thick foam layer, while the cortado is smaller and more concentrated.
• Cortado vs Cappuccino: A cappuccino has equal parts espresso, steamed milk, and foam, whereas the cortado has only a small amount of microfoam.

Ingredients and Equipment You’ll Need

To make an authentic cortado at home, you’ll need a few key ingredients and tools. Start with freshly roasted coffee beans—ideally a medium to dark roast with chocolatey or nutty notes that complement the milk. For the espresso, you can use a dedicated espresso machine, a stovetop moka pot, or even an AeroPress with a fine filter. Fresh milk is essential; whole milk gives the creamiest texture, but oat or almond milk works well for dairy-free versions.

You’ll also need a milk frother or steam wand to create smooth microfoam. A small glass or ceramic cup (around 150 ml) is traditional for serving. If you’re using a moka pot, aim for a strong, concentrated brew that mimics espresso. For the best results, grind your beans just before brewing—a fine grind similar to table salt is ideal. At Square Mile, our The Filter Blend is a fantastic choice for a balanced, versatile coffee that works well in a cortado.

• Freshly roasted coffee beans (e.g., The Filter Blend)
• Espresso machine, moka pot, or AeroPress
• Whole milk or alternative milk (oat, almond)
• Milk frother or steam wand
• Small glass or ceramic cup (150 ml)
• Digital scale and timer for consistency

Step-by-Step Guide to Making a Cortado

Step 1: Prepare your espresso. Start by grinding your coffee beans to a fine consistency. For a single cortado, you’ll need a double shot of espresso (about 18–20 grams of coffee) yielding 36–40 grams of liquid. Brew your espresso into a small cup or shot glass. If you’re using a moka pot, brew a strong, concentrated batch and measure out 40–50 ml.

Step 2: Steam your milk. Pour cold milk into a frothing pitcher (about 100 ml for one cortado). Insert the steam wand just below the surface and turn it on, creating a gentle whirlpool. Heat until the milk reaches 60–65°C (140–150°F) and has a velvety, glossy microfoam—no large bubbles. If you don’t have a steam wand, use a handheld frother or shake the milk in a jar, then microwave for 30 seconds.

Step 3: Combine and serve. Pour the steamed milk directly into the espresso, holding back the foam with a spoon if needed. The final ratio should be roughly 1:1 espresso to milk. The drink should fill about two-thirds of your cup, leaving room for a thin layer of microfoam on top. Serve immediately and enjoy the balanced, smooth flavour.

• Use a digital scale to measure your espresso yield for consistency.
• Tap the milk pitcher on the counter to break any large bubbles before pouring.
• For a dairy-free cortado, oat milk froths beautifully and complements coffee’s natural sweetness.

Tips for the Perfect Cortado at Home

To elevate your cortado, focus on the quality of your espresso. Freshly roasted beans make a significant difference—stale beans will produce a flat, bitter shot. Experiment with different origins to find your favourite flavour profile. For example, washed espressos often have bright, fruity notes that pair wonderfully with milk. If you’re looking for a consistent, high-quality option, consider a subscription like Our Pick Washed Espresso Subscription - Gift, which delivers freshly roasted beans to your door.

Temperature control is also crucial. Overheated milk can scorch and taste burnt, while cold milk won’t integrate properly. Aim for 60–65°C (140–150°F) for the perfect balance. Finally, practice your pouring technique—a steady hand and a low pour will help the milk and espresso blend smoothly, creating that signature velvety texture.

• Preheat your cup with hot water to keep the cortado warm longer.
• Use filtered water for your espresso to avoid off-flavours from tap water.
• Clean your steam wand immediately after use to prevent milk residue buildup.

Why the Cortado is Perfect for Home Baristas

The cortado is an ideal drink for home baristas because it’s small, quick to make, and doesn’t require a lot of milk or coffee. It’s also a great way to practice your espresso and milk steaming skills without the pressure of a large latte. Plus, its balanced flavour profile makes it a crowd-pleaser—even non-coffee drinkers often enjoy its creamy yet bold taste.

If you’re new to home brewing, starting with a cortado can help you understand the importance of ratios and milk texture. It’s also a fantastic canvas for experimenting with different beans. For a truly special treat, pair your cortado with a piece of dark chocolate or a biscotti. And if you’re ever unsure about your technique, remember that practice makes perfect—each cortado you make will bring you closer to barista-level quality.

Now that you know how to make a cortado at home, it’s time to put your skills to the test. Start with freshly roasted beans like The Filter Blend for a balanced, delicious base, and enjoy the process of crafting this classic Spanish coffee. Whether you’re a seasoned home barista or just beginning your coffee journey, the cortado is a rewarding drink that showcases your brewing prowess.
