Cappuccino

Flat White

A cappuccino features equal parts espresso, steamed milk, and thick foam in a 150-180 ml (5-6 oz) serving, while a flat white contains double espresso shots with microfoam-textured milk in a 160-180 ml (5.4-6 oz) cup. The primary difference lies in foam thickness and espresso intensity—cappuccinos deliver airy, dry foam topping, whereas flat whites offer velvety microfoam throughout.

The cappuccino vs flat white debate centers on texture preference and caffeine content. Cappuccinos contain 63-126 mg caffeine from one espresso shot, compared to flat whites’ 126-252 mg from two shots. Milk ratios differ significantly: cappuccinos split milk and foam equally (1:1:1 ratio), while flat whites emphasize steamed milk with minimal foam (2:1 ratio).

In this cappuccino vs flat white guide, we’ll compare serving sizes, espresso strength, foam textures, taste profiles, and pricing. You’ll learn which drink suits your morning routine, whether you prefer bold espresso flavor or smooth milk texture, and how each beverage fits different café occasions.

What’s the Difference Between Cappuccino and Flat White?

The core distinction between these espresso drinks begins with their construction method. Cappuccinos follow the traditional Italian 1:1:1 formula—one part espresso (30 ml/1 oz), one part steamed milk (30 ml/1 oz), and one part aerated foam (30 ml/1 oz). Baristas create this thick foam layer by introducing more air during the milk steaming process, resulting in a dry, structured cap that sits prominently atop the drink.

Flat whites originated in Australia and New Zealand during the 1980s, emphasizing espresso strength through double shots (60 ml/2 oz total). The milk preparation differs fundamentally—baristas create microfoam by incorporating minimal air, producing silky-textured milk rather than separated foam layers. This technique yields a glossy surface with fine bubbles integrated throughout, similar to how a flat white vs latte comparison reveals different milk textures in espresso-based drinks.

Taste profiles diverge due to these structural differences. Cappuccinos deliver distinct layers you experience sequentially: foam first, then milk, finally espresso at the bottom. The thick foam insulates the drink, maintaining temperature longer while creating a lighter mouthfeel. Flat whites present a unified flavor from first sip to last—strong espresso balanced by creamy milk without foam interference. The higher espresso-to-milk ratio in flat whites produces more intense coffee flavor compared to cappuccinos’ mellower profile.

Serving traditions also vary. Cappuccinos appear in 150-180 ml (5-6 oz) cups, often with cocoa powder or cinnamon dusting on foam. Flat whites arrive in 160-180 ml (5.4-6 oz) ceramic cups without garnish, letting the latte art shine on the microfoam surface. Italian cafés typically serve cappuccinos only before 11 AM, while flat whites suit any time of day in Australian and global café culture.

Is a cappuccino stronger than a flat white?

No, flat whites contain stronger coffee flavor due to double espresso shots (60 ml/2 oz total) compared to cappuccinos’ single shot (30 ml/1 oz). Flat whites deliver 126-252 mg caffeine while cappuccinos provide 63-126 mg. The microfoam in flat whites doesn’t dilute espresso taste, whereas cappuccino foam creates lighter overall flavor.

Which has more milk: cappuccino or flat white?

Flat whites contain more steamed milk volume—approximately 100-120 ml (3.4-4 oz) compared to cappuccinos’ 60 ml (2 oz) milk plus 60 ml (2 oz) foam. However, cappuccinos have greater total dairy volume when foam is included. The cappuccino flat white latte comparison shows flat whites fall between cappuccinos and lattes in milk content.

Can you make a cappuccino or flat white with oat milk?

Yes, both drinks work with oat milk, though results vary. Oat milk froths well for cappuccino foam but produces slightly less volume than dairy. For flat whites, barista-blend oat milk creates acceptable microfoam texture, maintaining the drink’s characteristic silkiness. Temperature control becomes more critical—oat milk performs best at 55-60°C (131-140°F).

Why do flat whites cost more than cappuccinos?

Flat whites typically cost €0.40-0.50 / $0.45-0.55 more due to double espresso shots requiring twice the coffee beans and extraction time. Additional milk volume (40-60 ml/1.4-2 oz extra) and specialized barista technique for microfoam also contribute to higher pricing. Premium positioning in café menus reflects the drink’s specialty coffee culture origins.

What’s the calorie difference between cappuccino and flat white?

Cappuccinos contain 70-120 kcal while flat whites range 110-160 kcal when made with whole milk. The 40-50 kcal difference results from flat whites’ greater milk volume and double espresso shots, similar to how cold brew vs iced coffee comparisons reveal calorie variations in coffee preparations. Switching to skim milk reduces both drinks by approximately 40-50 kcal, similar to how cold brew vs iced coffee comparisons reveal calorie variations in coffee preparations.

Do cappuccinos and flat whites taste the same?

No, flavor profiles differ significantly. Cappuccinos taste milder with distinct foam, milk, and espresso layers creating varied texture experience. Flat whites deliver stronger, more uniform coffee flavor throughout due to integrated microfoam and double espresso concentration. The cappuccino flat white difference in espresso-to-milk ratios produces noticeably distinct taste experiences.

Which drink is better for latte art?

Flat whites offer superior latte art canvas due to glossy microfoam surface and minimal foam thickness (0.3-0.5 cm/0.1-0.2 in). Baristas can create intricate patterns—hearts, rosettas, tulips—that remain visible throughout drinking. Cappuccino foam (1.5-2 cm/0.6-0.8 in thick) accepts basic designs but the airy texture makes detailed patterns difficult, similar to how black tea vs green tea preparations require different steeping techniques for optimal results
