How to Make the Perfect Flat White at Home: A Home Barista Guide

The flat white is a beloved coffee classic—a velvety, rich espresso-based drink that originated in Australia and New Zealand. Unlike a latte, it features a thin layer of microfoam and a stronger coffee flavour, making it a favourite for those who appreciate a balanced, creamy cup without too much milk.

While it might look simple, achieving the perfect flat white at home requires a bit of technique and the right equipment. In this guide, we'll walk you through the essential steps, from pulling a flawless espresso shot to steaming milk to silky perfection. Whether you're a home barista or just starting out, you'll soon be brewing flat whites that rival your favourite café.

What Makes a Flat White Different?

At its core, a flat white is a double espresso topped with a thin layer of steamed milk and microfoam. The key difference from a latte is the milk texture: flat white foam is finer and less voluminous, creating a velvety mouthfeel. A cappuccino, on the other hand, has a thicker, drier foam layer.

The flat white also typically uses a smaller milk-to-coffee ratio than a latte, which means the coffee flavour shines through more prominently. This makes it an ideal drink for showcasing high-quality espresso beans—especially a well-balanced blend like our Red Brick Espresso, which offers notes of dark chocolate and stone fruit that pair beautifully with milk.

• Double espresso base (not single)
• Thin, velvety microfoam—not stiff or bubbly
• Smaller milk volume than a latte (usually 150–180ml)

Essential Equipment for a Home Flat White

To make a flat white at home, you need a few key pieces of equipment. First, a quality espresso machine that can produce consistent pressure and temperature. A machine like the Sage Barista Pro is an excellent choice for home baristas, offering a built-in grinder and precise temperature control. Alternatively, a manual espresso maker or a stovetop moka pot can work, though the results will differ.

You'll also need a good grinder for fresh coffee beans, a tamper, a milk pitcher, and a thermometer (or a steam wand with good control). Don't forget fresh, high-quality coffee—our Half Caff blend is a great option if you want a lower-caffeine flat white without sacrificing flavour.

• Espresso machine with a steam wand (e.g., Sage Barista Pro)
• Freshly roasted coffee beans (try Half Caff for a balanced option)
• Milk pitcher (preferably stainless steel with a spout)
• Digital thermometer (optional but helpful)

Step 1: Pull the Perfect Espresso Shot

The foundation of any great flat white is a well-extracted double espresso. Start by grinding your coffee beans to a fine consistency—similar to table salt. For a double shot, aim for 18–20 grams of coffee, yielding about 36–40 grams of liquid in 25–30 seconds. The water temperature should be around 93°C.

If you're using a subscription service like our Prepaid Red Brick Espresso Subscription Monthly 6 months, you'll always have fresh beans on hand. Red Brick's rich, chocolatey profile is ideal for milk-based drinks, giving your flat white a deep, satisfying flavour.

• Use 18–20g of coffee for a double shot
• Extract 36–40g of liquid in 25–30 seconds
• Aim for a golden-brown crema with no blonding

Step 2: Steam Milk to Silky Microfoam

Steaming milk for a flat white is all about creating a smooth, glossy microfoam without large bubbles. Start with cold milk (whole milk works best for texture, but oat or almond milk can also work). Submerge the steam wand tip just below the surface and turn it on. As the milk expands, lower the pitcher slightly to incorporate air, then submerge the wand deeper to heat the milk to 60–65°C.

The goal is a velvety, paint-like consistency—not stiff foam. Tap the pitcher on the counter to pop any large bubbles, then swirl it gently to integrate the foam. For best results, use fresh milk and a clean steam wand.

• Use cold milk (whole milk for best texture)
• Steam to 60–65°C—never overheat
• Aim for a glossy, paint-like microfoam

Step 3: Assemble Your Flat White

Once you have your espresso and steamed milk ready, it's time to combine them. Pour the milk into the centre of the espresso from a height of about 10–15 cm, allowing the milk to mix with the coffee. As the cup fills, lower the pitcher and pour more slowly to create a thin layer of foam on top.

A traditional flat white is served in a small ceramic cup (around 160–200ml) and doesn't have latte art—though a simple dot or heart is a nice touch. The key is balance: the coffee should be the star, with the milk adding creaminess without overwhelming.

• Pour milk from height to integrate, then lower for foam
• Serve in a small cup (160–200ml)
• No need for elaborate latte art—keep it simple

Tips for Perfecting Your Flat White

Practice makes perfect when it comes to flat whites. If your foam is too thick, you've incorporated too much air—try steaming with the wand deeper in the milk. If the drink tastes weak, adjust your coffee dose or grind finer. Freshness matters: use beans roasted within the last 2–4 weeks for the best flavour.

Experiment with different coffee blends to find your favourite. Our Red Brick Espresso is a classic choice, but The Filter Blend Subscription offers a lighter, fruitier profile that also works well. And if you prefer a caffeine-free option, our decaf subscriptions are just as delicious.

• Use fresh, high-quality coffee beans
• Adjust grind size and dose to taste
• Clean your equipment regularly to avoid off flavours
