How to Make Flat White: Step-by-Step Guide

The flat white stands as Australia's gift to the coffee world—a sophisticated espresso drink that delivers intense coffee flavor through a velvety milk texture. Unlike the foam-dominant cappuccino or the milk-heavy latte, the flat white achieves perfect harmony through its distinctive 1:2 ratio and signature microfoam integration.

Core Definition: What Is a Flat White?

A flat white is defined as an espresso-based beverage consisting of a double shot of espresso combined with steamed milk at a 1:2 ratio, topped with a thin layer of microfoam approximately 1-2 millimeters thick. The flat white originated in Australia and New Zealand during the 1980s and represents an evolution of the Italian cappuccino adapted to Antipodean coffee preferences.

The flat white differs from the cappuccino by its significantly reduced foam amount—the "flat" in flat white refers to the lack of a prominent foam dome that characterizes cappuccinos. The flat white also differs from the latte by its stronger espresso presence (less milk dilution) and smaller serving size. This composition creates a drink where espresso flavor remains dominant while milk adds creaminess and body.

Traditional flat white preparation demands precise microfoam texture—bubbles so fine they're barely visible, creating a glossy, paint-like consistency that integrates seamlessly with the espresso. The flat white is typically served in a 6-8 ounce ceramic cup or tulip-shaped bowl, smaller than standard latte vessels to maintain the concentrated flavor profile.

Flat White vs Latte vs Cappuccino: Complete Comparison

The flat white, latte, and cappuccino represent three distinct philosophies in milk-based espresso preparation. Understanding the differences between flat white and latte, and flat white vs cappuccino, helps you craft each beverage correctly and appreciate their unique characteristics.

Step-by-Step Flat White Recipe

Step 1: Extract Double Espresso

Begin by grinding 18-20 grams of freshly roasted espresso beans to a fine consistency—similar to powdered sugar or fine sand. The grind size is critical for proper extraction; too coarse produces weak, sour espresso, while too fine creates bitter, over-extracted shots.

Distribute the grounds evenly in your portafilter basket using a distribution tool or by tapping the portafilter sides. Tamp with approximately 30 pounds of pressure using a flat, level tamper. An uneven tamp leads to channeling, where water bypasses portions of the coffee puck, resulting in unbalanced extraction.

Lock the portafilter into your espresso machine group head and extract immediately. Target a double shot yield of 36-40 grams of liquid espresso over 25-30 seconds. The espresso should flow in a steady, mouse-tail stream with rich, golden-brown crema covering the surface. Pour into a preheated 6-8 oz cup.

Step 2: Create Velvety Microfoam

Pour 4-6 ounces of cold whole milk into a stainless steel milk pitcher. The cold temperature provides a longer steaming window before the milk overheats. Position the steam wand tip just below the milk surface at a 15-20 degree angle, with the steam holes partially exposed to air.

Open the steam valve fully. You should hear a subtle "tearing paper" or "kissing" sound as air incorporates into the milk—this is the stretching phase. For flat white microfoam, limit stretching to 2-3 seconds (less than cappuccino, more than latte). The goal is minimal air incorporation for the finest possible bubbles.

Immediately submerge the wand tip completely and angle the pitcher to create a whirlpool vortex. This vortex breaks down larger bubbles and integrates the foam throughout the milk. Continue steaming until the pitcher becomes too hot to hold comfortably—approximately 150-155°F (65-68°C).

Remove the wand, wipe immediately, and purge steam. Tap the pitcher firmly on the counter 2-3 times to pop any surface bubbles, then swirl vigorously to polish the milk. Properly textured flat white milk resembles glossy white paint with no visible bubbles—completely smooth and velvety.

Step 3: Pour and Integrate

Hold the milk pitcher low—approximately 1-2 inches above the espresso surface. Begin pouring slowly into the center of the cup, allowing the milk to sink beneath the crema and integrate with the espresso. The initial pour should be gentle to preserve the crema while beginning the mixing process.

As the cup fills, gradually raise the pitcher and increase pour speed. For latte art, bring the pitcher tip close to the surface when the cup is 2/3 full and wiggle gently to create patterns. The flat white's minimal foam allows for detailed art designs that showcase barista skill.

The finished flat white displays a uniform, light caramel color with a thin, glossy microfoam layer (1-2mm) on top. Unlike the cappuccino's foam dome, the flat white surface should be nearly level with the cup rim—hence "flat." The microfoam integrates completely with the espresso rather than floating separately.

The 1:2 Ratio: Flat White Foundation

The 1:2 espresso-to-milk ratio distinguishes the flat white from all other milk-based espresso beverages. This proportion means the flat white contains approximately 33% espresso and 67% milk—more concentrated than a latte but more diluted than a cortado.

This 1:2 ratio ensures the flat white delivers pronounced espresso flavor while maintaining the creamy, drinkable quality that milk provides. The ratio also enables latte art—the milk's fluidity from minimal foam allows detailed patterns impossible with cappuccino's thick foam layer.

Microfoam Mastery: The Flat White Signature

Microfoam is defined as steamed milk containing bubbles so small (microscopic) they create a glossy, paint-like texture without visible foam separation. The flat white's microfoam quality separates amateur attempts from professional execution.

Microfoam Characteristics by Drink

Achieving flat white microfoam requires specific technique: minimal air incorporation (2-3 seconds stretching), aggressive vortex creation to break down bubbles, and proper temperature control. The result should be milk so finely textured it pours like heavy cream and integrates completely with espresso.

Flat White Equipment and Setup Costs

Creating authentic flat whites at home requires investment in quality equipment. The flat white's microfoam demands are higher than cappuccinos, necessitating a machine with sufficient steam power.

Final Thoughts

The flat white represents the evolution of espresso milk drinks—born from Australian and New Zealand coffee culture's demand for espresso-forward beverages with refined texture. Its 1:2 ratio and microfoam texture create a drinking experience that honors the coffee while showcasing milk's ability to enhance rather than mask.

Mastering the flat white at home requires attention to detail: proper double espresso extraction, precise milk steaming technique, and accurate ratio measurement. The reward is a café-quality beverage that delivers intense coffee flavor in a silky, drinkable format.

Whether you prefer your flat white pure or adorned with latte art, the fundamentals remain constant—quality espresso, velvety microfoam, and the perfect balance between the two. Practice the technique, respect the ratio, and enjoy one of coffee's most harmonious creations.
