Definition and Origins of a Flat White

The flat white is a specialty coffee characterized by its velvety microfoam texture, balanced strength, and precise coffee-to-milk ratio. Originating in Australia and New Zealand, it distinguishes itself from other espresso-based drinks through its emphasis on a smooth, silky foam layer and a more concentrated coffee base. This drink exemplifies modern coffee culture’s shift toward refined techniques and flavor harmony, blending Italian espresso traditions with Pacific innovation.

The flat white’s identity rests on three core elements: a 1:1 coffee-to-milk ratio (by volume), a thin but dense layer of microfoam (typically 1–2 mm thick), and a serving size of 120–150 mL. Unlike its Italian counterparts, it prioritizes a single shot of espresso (18–22 g) rather than a double, ensuring a stronger, more nuanced flavor profile. Visually, it appears as a smooth, uniform surface with minimal contrast between the coffee and milk, reflecting its emphasis on texture over visual flair.

Core Components of a Flat White

The flat white’s defining characteristics stem from its technical execution and ingredient proportions. Below are the key elements that differentiate it from other espresso drinks:
    The coffee-to-milk ratio is strictly 1:1, meaning equal parts espresso and steamed milk by volume. This ensures a bold yet balanced flavor without overwhelming sweetness or acidity. For example, a 150 mL flat white consists of 75 mL espresso and 75 mL microfoam-infused milk, achieved through precise steaming techniques.

    The microfoam is the flat white’s signature texture, created by slowly incorporating air into the milk while heating it to 60–65°C. This results in a fine, velvety foam with tiny, evenly distributed bubbles (unlike the thicker foam of a cappuccino or the liquid-heavy texture of a latte). The foam’s silky consistency enhances the coffee’s body without masking its subtle notes.

    The serving vessel typically ranges from 120–150 mL, smaller than a latte but larger than a cappuccino. This size accommodates the single-shot espresso base, which is 18–22 g (or a double shot of 25–30 g in some variations). The use of a single shot intensifies the coffee’s aromatic complexity, making it ideal for high-quality beans.

    The visual presentation is minimalist: a smooth, unbroken surface with a barely perceptible foam layer (often no more than 1–2 mm thick). Unlike a latte (which may have a 1–2 cm foam layer) or a cappuccino (with a 1:1:1 coffee-steamed milk-foam ratio), the flat white’s subtle foam ensures the drink’s flavor and texture dominate over aesthetics.

Historical Origins and Evolution

The flat white emerged in the late 1980s to early 1990s in Australia and New Zealand, evolving from Italian espresso traditions adapted to local tastes. Its development reflects a cultural fusion between European coffee techniques and Pacific coffee culture, emphasizing simplicity, quality, and craftsmanship.
    The flat white’s direct precursor was the Italian cappuccino, which traditionally used a double shot of espresso with equal parts steamed milk and foam. Australian baristas, however, sought a stronger, more concentrated drink that retained the smoothness of milk without diluting the coffee’s intensity. This led to the adoption of a single shot and a reduced foam layer, creating a more potent yet velvety experience.

    The name "flat white" originated from its lack of a thick foam "head" (unlike a cappuccino’s pronounced foam) and its smooth, almost "flat" surface. The term was popularized in Sydney and Melbourne by baristas who refined the drink to highlight bean quality and brewing precision. By the mid-1990s, it had become a staple in Australian cafés, later gaining global recognition as a signature of specialty coffee culture.

    The flat white’s export to New Zealand followed shortly, where it was further refined to emphasize lighter roasts and brighter flavor profiles, aligning with the country’s artisan coffee movement. Today, it is a cornerstone of specialty coffee menus worldwide, often positioned as a mid-strength alternative between a ristretto (strong, short espresso) and a latte (milder, milk-forward).

Comparison with Similar Espresso-Based Drinks

The flat white shares foundational elements with lattes, cappuccinos, and macchiatos but differs in strength, texture, and milk incorporation. Below is a comparative analysis of its key distinguishing features:
Feature Flat White Latte Cappuccino Macchiato
Coffee Base Single shot (18–22 g) or double shot (25–30 g) Double shot (25–30 g) Double shot (25–30 g) Single shot (18–22 g) with minimal milk
Milk Ratio 1:1 coffee-to-milk (by volume) 1:3 coffee-to-milk (1/3 foam, 2/3 liquid) 1:1:1 coffee-steamed milk-foam 1:10 or less (espresso dominates)
Foam Texture Microfoam (1–2 mm, velvety) Thin foam layer (1–2 cm, slightly wet) Thick, dry foam (1/3 of drink) Minimal or no foam (often "dry" or "wet")
Serving Size 120–150 mL 240–360 mL 150–180 mL 30–60 mL
Strength Intensity Strong (single shot) but balanced Moderate (diluted by milk) Moderate (foam reduces concentration) Very strong (minimal milk)
Visual Appearance Smooth, uniform surface Liquid with thin foam layer Distinct foam "head" Espresso with milk "stain"
The flat white’s unique positioning lies in its balance of intensity and smoothness, making it a preferred choice for those seeking a stronger alternative to a latte without the bitterness of a straight espresso or the heaviness of a cappuccino’s foam. Its microfoam technique ensures the milk enhances rather than overwhelms the coffee’s natural flavors, a hallmark of specialty coffee preparation.

Coffee and Milk Preparation Techniques for the Flat White

The flat white achieves its signature balance of rich espresso and velvety microfoam through precise brewing and milk texturization. Mastery of these techniques ensures a harmonious flavor profile, where the espresso’s intensity is complemented—not overpowered—by the milk’s subtle sweetness. Below are the step-by-step protocols for crafting the ideal espresso base and achieving the signature microfoam consistency, along with a checklist to mitigate common preparation errors.

Espresso Base Preparation

The foundation of a flat white lies in a well-extracted espresso with a 1:2 ratio (18–22g of coffee to 36–44g of liquid) and a total extraction time of 25–30 seconds. Key variables include grind size, dose, yield, and water temperature, all of which influence extraction efficiency and flavor development.

Grind Size and Dose

  • Use a medium-fine grind, comparable to table salt, to achieve resistance of 9–10 bars (measured at the group head).
  • A 18–22g dose (standard for a double shot) ensures sufficient surface area for extraction while maintaining consistency.
  • Burr grinders are preferred over blade grinders to ensure uniformity; particle size variations lead to channeling and uneven extraction.

    • Extraction Parameters

  • Water temperature should be 90–96°C (194–205°F) to avoid over-extraction (bitterness) or under-extraction (sourness).
  • Yield should be 36–44g (double the dose) to maintain the 1:2 ratio, with a flow rate of 1–2 seconds per gram of coffee (e.g., 18g dose yields ~1 drop per second).
  • Pre-infusion (if available) saturates the coffee bed evenly, reducing channeling and improving extraction uniformity.

    • Post-Extraction Assessment

  • The espresso should exhibit a caramel-to-dark brown color with a thick, syrupy crema (1–2mm deep).
  • Taste profile should balance sweetness, acidity, and bitterness, with no dominant sour or burnt notes.
  • Blockquote:
    • > "A properly extracted espresso for a flat white should taste like a concentrated version of the coffee’s intended flavor—neither overly harsh nor muddled."

    Steaming Milk to Microfoam Consistency

    Microfoam is the defining characteristic of a flat white, achieved through controlled aeration and emulsification of milk. The process requires a steam wand with adjustable pressure (typically 1–1.5 bars) and a pitcher with a 300–400ml capacity (preferably stainless steel for heat retention).

    Equipment and Setup

  • Steam wand should be purge-free and capable of producing a tight, conical stream (not a wide spray).
  • Pitcher should be chilled (place in cold water for 1–2 minutes) to prevent overheating and scorching.
  • Milk choice is typically whole milk (3.5–4% fat) for optimal creaminess, though barista-style oat or 2% milk can substitute with adjusted technique.

    • Steaming Technique
    1. Submerge the wand 1–2cm below the milk’s surface at a 45° angle, creating a vortex to incorporate air.
    2. Listen for sound cues:

  • Initial "hiss" indicates air incorporation; maintain this for 2–3 seconds to create microbubbles.
  • Transition to a "paper-tearing" sound signals emulsification; reduce pitch slightly to avoid large bubbles.
    • 3. Stretch the milk to 50–60°C (122–140°F) by lowering the pitcher and adjusting wand depth to control heat transfer.
    4. Finish with a "whip" by briefly raising the pitcher to introduce small, even bubbles without over-foaming.

    Visual and Textural Targets

  • Final volume should increase by 30–50% (e.g., 100ml → 130–150ml).
  • Consistency should resemble wet paint or heavy cream, with no large bubbles or dry foam.
  • Temperature should not exceed 65°C (149°F) to preserve milk proteins and avoid a cooked flavor.

    • Common Mistakes in Flat White Preparation and Corrections

    Errors in technique often stem from equipment limitations, improper timing, or inconsistent measurements. Below is a checklist of frequent pitfalls and their solutions, categorized by preparation stage.

    Espresso-Related Errors

    "Uneven extraction is the primary cause of imbalanced flat whites; address it through grind adjustments and dose consistency."
  • Channeling (water bypassing coffee grounds):
  • Cause: Over-extraction, coarse grind, or uneven tamp.
  • Fix: Reduce grind size, increase dose, or use a WDT (weight distribution tool) for even tamping.
  • Over-extraction (bitter, burnt taste):
  • Cause: Too fine grind, high water temperature, or prolonged extraction.
  • Fix: Coarse grind, reduce temperature to 90–92°C, or aim for 25–28 seconds total.
  • Under-extraction (sour, weak flavor):
  • Cause: Too coarse grind, low water temperature, or insufficient yield.
  • Fix: Fine grind, increase temperature to 94–96°C, or extend extraction to 30 seconds.

    • Milk Steaming Errors

  • Large bubbles or dry foam:
  • Cause: Wand too deep, high pressure, or over-steaming.
  • Fix: Submerge wand 1–2cm, reduce pressure to 1 bar, and stop at 50–60°C.
  • Scorched or burnt milk:
  • Cause: Overheating due to prolonged steaming or poor pitcher chilling.
  • Fix: Use a chilled pitcher, steam for 10–15 seconds max, and monitor temperature with a thermometer.
  • Under-steamed milk (no aeration):
  • Cause: Wand too shallow, low pressure, or insufficient vortex.
  • Fix: Submerge wand deeper (3–4cm), increase pressure to 1.2–1.5 bars, and create a strong vortex initially.

    • Assembly and Serving Errors

  • Weak or watery flat white:
  • Cause: Insufficient espresso dose or over-diluted milk.
  • Fix: Use 18–22g espresso and 150–180ml steamed milk (ratio 1:7 to 1:8).
  • Layering (espresso and milk separate):
  • Cause: Milk poured too quickly or at an angle.
  • Fix: Pour milk slowly in a spiral, holding the pitcher 1–2cm above the cup to create a whirlpool effect.
  • Over-foamed top (dry, unstable):
  • Cause: Excessive aeration or high milk temperature.
  • Fix: Aim for 30–50% volume increase and cap temperature at 60°C.

      Equipment and Tools for Crafting the Perfect Flat White

      The preparation of a flat white demands precision in both coffee extraction and milk texturization, requiring specialized equipment to achieve consistency and quality. Professional-grade tools optimize performance, while budget-friendly alternatives offer accessible options for home baristas. This section examines the essential equipment—espresso machines, grinders, and milk frothers—along with selection criteria, troubleshooting techniques, and performance considerations to ensure a well-executed flat white.

      Essential Equipment for Flat White Preparation

      The foundation of a flat white lies in three core components: an espresso machine for extraction, a grinder for consistent particle size, and a milk frother or steam wand for silky microfoam. Each tool contributes uniquely to the drink’s balance of rich coffee and velvety milk.

      Espresso Machines
      Espresso machines are categorized by heat source (thermo-block, PID-controlled, or heat exchangers) and pressure systems (direct-piston or spring-driven). For flat whites, machines with stable temperature control (±0.5°C) and adjustable pressure (9–10 bars) are ideal. Home baristas often rely on semi-automatic machines (e.g., Breville Bambino, Gaggia Classic), while cafés use commercial dual-boiler models (e.g., La Marzocco Linea Mini, Rancilio Silvia).

      Grinders
      Grind consistency directly impacts extraction time and flavor. Burr grinders (conical or flat) are preferred for their precision. Key specifications include:

    • Grind size adjustment (fine for espresso, ~18–20 microns).
    • Material durability (ceramic for quiet operation, steel for longevity).
    • RPM range (higher RPMs reduce heat buildup, ideal for flat whites).

      Flavor Profiles and Pairings in the Flat White

      A well-crafted flat white is a symphony of sensory elements, where the precise balance of espresso and velvety microfoam creates a harmonious experience. Its flavor profile is defined by a delicate interplay of aroma, acidity, body, and aftertaste, each contributing to its distinct character. Understanding these attributes allows baristas and enthusiasts to refine preparation techniques and pair the coffee with complementary foods and beverages. Below, the sensory characteristics of a flat white are explored, followed by curated pairings and alternative milk options that enhance its complexity.

      Sensory Characteristics of a Flat White

      A flat white exhibits a refined and layered flavor profile that distinguishes it from other espresso-based drinks. The aroma is typically vibrant, with notes of caramelized sugars, toasted nuts, and subtle floral or fruity undertones, depending on the bean origin. For example, a flat white made with Ethiopian beans may present bright citrus or berry aromas, while a Colombian roast often delivers chocolatey and nutty scents.

      The acidity in a flat white is balanced yet perceptible, contributing to its liveliness without overpowering the sweetness. A well-extracted shot should exhibit a moderate body, neither syrupy nor watery, with a smooth texture facilitated by the fine microfoam. The aftertaste is where the flat white’s artistry shines—it lingers with a clean, slightly sweet finish, often echoing the initial aroma with a hint of lingering bitterness or complexity.

      A flat white’s ideal texture is described as "silky," where the microfoam integrates seamlessly with the espresso, creating a mouthfeel that is both rich and airy.
      The preparation method—particularly the use of double ristretto shots (1:1 or 1:2 coffee-to-water ratio) and fine, velvety microfoam—amplifies these qualities. A properly pulled shot should have a viscosity akin to heavy cream, allowing the flavors to unfold gradually rather than overwhelming the palate.

      Pairing Guide for Flat Whites

      The flat white’s balanced sweetness, moderate acidity, and velvety texture make it versatile for pairing with both sweet and savory accompaniments. Below is a structured guide to enhance its flavor profile through complementary foods and beverages.

      Fresh fruit tarts (e.g., raspberry or passionfruit) The tartness of the fruit cuts through the coffee’s richness, while the buttery crust provides a neutral base to highlight both flavors.
      Savory Pairings Ricotta and honey on toasted sourdough The tangy creaminess of ricotta and the subtle sweetness of honey mirror the flat white’s texture, while the sourdough’s crust adds a satisfying crunch.
      Smoked salmon with cream cheese The umami depth of smoked salmon and the mild richness of cream cheese provide a savory counterpoint to the flat white’s sweetness, ideal for breakfast pairings.
      For optimal pairing, consider the origin of the coffee beans:
    • African beans (e.g., Ethiopian, Kenyan) pair well with bright, citrusy pastries or fruity chocolates.
    • South American beans (e.g., Colombian, Brazilian) complement nutty, caramelized treats or spiced beverages.
    • Asian beans (e.g., Sumatran) harmonize with earthy, umami-rich pairings like matcha or dark chocolate.

      • Alternative Milk Options and Their Impact

      While whole milk is the traditional choice for a flat white, alternative milks can significantly alter the drink’s taste and texture. The selection of milk should align with the desired flavor profile and dietary preferences, with adjustments made to preparation techniques to maintain balance.
      The ideal milk for a flat white should integrate smoothly with the espresso, neither overwhelming its flavor nor diluting its intensity.
      The following list outlines alternative milks, their flavor contributions, and necessary preparation adjustments:
      • Oat Milk
      • Flavor/Texture: Naturally sweet with a creamy, slightly grainy mouthfeel. Lacks the richness of dairy but adds a subtle caramelized note.
      • Adjustments: Use a barista-style oat milk (higher fat content) to improve foam stability. Steam longer to achieve a thicker microfoam, as oat milk can be less stable. A ristretto shot (shorter extraction) may be preferable to avoid bitterness.
      • Best For: Flat whites with chocolatey or nutty beans, as the natural sweetness complements these profiles.
      • Almond Milk
      • Flavor/Texture: Light and nutty, with a thinner consistency that can make the flat white taste more watery if not prepared carefully. Often lacks the fat needed for proper foam.
      • Adjustments: Opt for unsweetened, high-fat almond milk (or blend with a splash of oat milk). Use a double ristretto to intensify the coffee’s flavor and add a dollop of whipped cream to compensate for the lack of foam. A slightly longer extraction (1:2 ratio) may help balance the drink.
      • Best For: Fruity or floral beans, where the nutty notes of almond milk can enhance the natural acidity.
      • Coconut Milk
      • Flavor/Texture: Rich and tropical, with a distinct coconut aroma that can overpower delicate coffee flavors. Thicker than dairy milk, requiring careful steaming.
      • Adjustments: Use light coconut milk (not cream) to avoid heaviness. Steam gently to create a smooth, glossy microfoam without breaking. A single ristretto shot may suffice, as the milk’s intensity can dominate.
      • Best For: Bold, dark-roasted beans with chocolatey or spiced notes, as the coconut’s sweetness harmonizes with these profiles.
      • Soy Milk
      • Flavor/Texture: Neutral yet slightly beany, with a creamy texture similar to dairy. Higher protein content allows for stable foam.
      • Adjustments: Steam aggressively to achieve a dense microfoam, as soy milk can be prone to splitting. A balanced extraction (

        • Visual and Textural Analysis of a Flat White

        The flat white stands as a masterclass in balance between espresso intensity and velvety milk integration, where visual and tactile elements define its identity. Unlike its more layered counterparts, such as the cappuccino or latte, the flat white prioritizes a harmonious fusion of coffee and milk, resulting in a dense yet silky texture and a distinct, almost monochromatic aesthetic. This analysis explores the ideal visual stratification, tactile nuances, and comparative textural distinctions that distinguish the flat white from other milk-based coffees, emphasizing the sensory precision achieved through barista technique and equipment.

        Visual Layers and Aesthetic Characteristics

        The flat white’s visual appeal lies in its minimalist yet deliberate composition, where each layer serves a functional and sensory purpose. The ideal presentation adheres to a three-tiered structure, though the boundaries between layers are intentionally blurred to create a cohesive appearance.

        - Espresso Layer (Base)
        The foundation consists of a single or double shot of espresso (30–40ml), extracted at a 1:2 ratio (18–22g of coffee to 36–44g of liquid). The espresso should exhibit a deep mahogany hue, with a smooth, glossy sheen—indicative of proper extraction and freshness. Microfoam integration begins immediately upon pouring, causing the espresso to lighten slightly at the edges without forming distinct streaks. A well-made flat white avoids the dark, concentrated "puddle" effect seen in under-extracted shots or the watery dilution of over-extracted ones.

        - Microfoam Transition Zone (Middle Layer)
        The microfoam—a fine, silky texture with a density of 30–40% air incorporation—should appear as a smooth gradient rather than a separate foam layer. Unlike cappuccino foam (which is drier and more structured), flat white microfoam is liquid-like yet aerated, allowing it to seamlessly blend with the espresso. The color shifts from dark brown at the bottom to a caramel or light tan at the top, with no visible white foam cap (a hallmark of latte art). The absence of a distinct foam layer distinguishes it from a latte, where foam is more pronounced and separate.

        - Surface Sheen and Latte Art Potential
        The surface of a flat white exhibits a velvety, satin-like finish, with minimal bubbles (diameter <1mm) that dissipate quickly upon stirring. While latte art is not the primary focus, subtle designs like a single leaf or heart can be achieved by pouring slowly in a spiral motion, leveraging the microfoam’s low viscosity. The key difference from other drinks lies in the lack of contrast: a flat white’s surface should appear uniform in tone, whereas a cortado may show more defined foam edges or a red eye may reveal espresso streaks through the milk.

        The flat white’s visual success depends on controlled pouring speed (3–5 seconds per shot) and microfoam consistency, where the milk’s surface tension is manipulated to create a single, seamless layer rather than distinct strata.

        Tactile Experience and Mouthfeel

        The tactile journey of a flat white begins with the cup temperature, progresses through the sip texture, and concludes with the mouthfeel’s evolution—each element influenced by brewing method, equipment, and milk preparation.

        - Cup Temperature and Initial Sensation
        The ideal serving temperature for a flat white ranges between 60–65°C (140–149°F), achieved by preheating the cup and saucer to 55–60°C (131–140°F). A properly heated cup ensures the drink retains heat for 10–15 minutes, preventing the milk from cooling too rapidly and losing its creamy mouthfeel. In contrast, a cold cup causes the milk to separate prematurely, resulting in a watery texture and bitter espresso dominance.

        - Sip Texture and Flow Dynamics
        The first sip of a barista-made flat white delivers a thick, almost syrupy consistency, with the microfoam providing a slight resistance before dissolving into a smooth, homogeneous liquid. The viscosity is higher than that of a latte (which feels lighter and more fluid) but less dense than a cappuccino (which has more structural foam). The lack of air pockets in the microfoam ensures a clean, uninterrupted sip, whereas home-brewed versions may exhibit larger bubbles due to whisking or frothing inconsistencies, leading to a grainier texture.

        Element Barista-Made Flat White Home-Brewed Flat White
        Microfoam Density 30–40% air incorporation, ultra-fine bubbles (<0.5mm) 40–50% air incorporation, visible bubbles (0.5–1.5mm)
        Sip Resistance Moderate (smooth, almost liquid-like) Higher (grainy, slightly aerated)
        Heat Retention 10–15 minutes (preheated cup) 5–10 minutes (inconsistent heating)
        Aftertaste Coating Even, creamy linger (no foam residue) Foamy or watery finish (incomplete integration)
      • Mouthfeel Evolution and Flavor Release
        • The initial mouthfeel is dominated by the microfoam’s lubricating effect, which softens the espresso’s acidity and amplifies sweetness. As the drink is consumed, the texture transitions from creamy to velvety, with the espresso’s body becoming more pronounced in the mid-palate. Unlike a cortado—where the espresso’s intensity is more abrupt—the flat white’s gradual flavor progression is due to its higher milk-to-coffee ratio (1:1 or 1:1.5), which dilutes harshness while preserving aromatic complexity.
        The flat white’s textural signature is its lack of foam separation: the drink should feel uniform in every sip, with no sudden shifts from creamy to foamy, unlike a latte or cappuccino.

        Comparative Textural Analysis: Flat White vs. Other Milk Coffees

        While the flat white shares similarities with cortados, lattes, and cappuccinos, its textural profile distinguishes it through milk integration, foam density, and structural cohesion. Below is a text-based illustration of how each drink’s texture differs upon consumption.

        The flat white stands as a testament to the marriage of simplicity and sophistication in coffee craftsmanship, where every sip reveals a story of precision, culture, and adaptation. From its humble origins in Melbourne cafés to its global dominance in specialty coffee menus, its allure lies in its ability to deliver a robust yet silky experience—one that challenges assumptions about milk-based coffees while remaining accessible to both baristas and home enthusiasts. As techniques evolve and palates diversify, the flat white continues to redefine standards, proving that even in an era of endless coffee variations, some classics endure not by standing still, but by mastering the art of balance.

        • FAQ

        What exactly is a flat white, and how does it differ from other coffee drinks?

        A flat white is an espresso-based coffee drink with velvety microfoam layered on top, served in a small cup (typically 150–180ml). It uses a double shot of espresso and a higher ratio of foam to milk compared to a cappuccino, creating a smoother, creamier texture with less froth.

        What kind of coffee is a flat white, and how is it prepared?

        A flat white is a type of espresso drink made with a double shot of espresso and steamed milk, topped with a thin layer of fine, silky microfoam. The milk is usually textured to a velvety consistency, distinct from the foamier top of a cappuccino or latte.

        What ingredients are used to make a flat white?

        A flat white is made with espresso (usually a double shot) and steamed milk, often whole milk, which is textured into a smooth microfoam. Some variations may include a touch of sweetener or flavored syrup, but the base ingredients remain espresso and milk.

        What is an iced flat white, and how is it different from a regular flat white?

        An iced flat white is a chilled version of the drink, made with espresso and cold milk (or milk poured over ice), topped with microfoam. The texture is less creamy than a hot flat white, and it’s served over ice to keep it cold, often with a straw for drinking.

        What is a flat white at Starbucks, and how does it compare to the traditional version?

        At Starbucks, a flat white is made with a double ristretto shot (a shorter, stronger espresso pull) and steamed milk, topped with a thin layer of foam. It’s sweeter and slightly stronger than a traditional flat white due to the ristretto and added vanilla or caramel syrup in some versions.

        Is a flat white stronger than a cappuccino, and why?

        Yes, a flat white is generally stronger than a cappuccino because it uses a double shot of espresso (like a latte) but with a higher milk-to-foam ratio, concentrating the coffee flavor. Cappuccinos have more foam and a milder espresso taste due to their larger milk volume.
