A cortado is a 1:1 ratio of espresso to warm milk (no foam), while a flat white uses more milk with microfoam and is larger overall. The cortado tastes stronger and more espresso-forward; the flat white is smoother and silkier.
Both are small espresso drinks that let the coffee speak — they just do it differently.
Quick Comparison Table
| Cortado | Flat White | |
|---|---|---|
| Espresso | 30–60 ml (double) | 30–60 ml (double, often ristretto) |
| Milk | 30–60 ml warm milk (1:1 ratio) | 100–130 ml microfoam |
| Total volume | ~60–120 ml (2–4 oz) | ~150–180 ml (5–6 oz) |
| Milk texture | Warm, minimal foam | Velvety microfoam (silky, no dry foam) |
| Strength | Strong — espresso-forward | Medium — balanced espresso and milk |
| Temperature | Slightly cooler (milk not fully steamed) | Hot (fully steamed microfoam) |
| Origin | Spain | Australia / New Zealand |
| Cup | Small glass (~4 oz) | Ceramic cup (~5–6 oz) |
What Is a Cortado?
A cortado (from the Spanish verb cortar — “to cut”) is espresso “cut” with an equal part of warm milk. The classic ratio is 1:1: 30 ml espresso to 30 ml milk, or 60 ml double shot to 60 ml milk.
The milk is steamed but not heavily textured — it’s warm and slightly velvety, but the goal isn’t microfoam. This keeps the cortado tasting primarily of espresso, with milk playing a supporting role to reduce acidity and soften bitterness.
Key cortado characteristics:
- Espresso:milk ratio = 1:1
- Minimal foam — milk is textured but not heavily frothed
- Served in a small glass (~4 oz / 120 ml)
- Strong, bold, espresso-forward flavor
- Less sweetness than a flat white
See our Cortado Recipe for step-by-step making instructions.
What Is a Flat White?
A flat white is espresso with a larger proportion of velvety microfoam milk, typically made with a double ristretto for a concentrated espresso base. The “flat” refers to the milk — it has a thin layer of microfoam that sits flat, without the thick dry foam cap of a cappuccino.
The flat white originated in Australia and New Zealand in the 1980s and is a defining drink of Antipodean coffee culture. It’s larger than a cortado and has a noticeably silkier, smoother texture.
Key flat white characteristics:
- More milk than a cortado — roughly 1:3 espresso to milk ratio
- Velvety microfoam steamed to about 60–65°C (140–150°F)
- Served in a 5–6 oz ceramic cup
- Balanced espresso-to-milk flavor
- Smoother and silkier than a latte (less milk) but less intense than a cortado

Key Differences Explained
1. Ratio Is Everything
The fundamental difference is how much milk each drink uses.
A cortado uses equal parts espresso and milk — if you have 60 ml espresso, you add 60 ml milk. The coffee dominates.
A flat white uses roughly 1 part espresso to 3 parts milk. With the same 60 ml espresso, you’d add about 100–130 ml of milk. The milk softens the coffee significantly.
2. Milk Texture Differs
Cortado milk is warm and lightly textured — you steam it gently to reduce acidity without creating foam. There should be minimal to no dry foam on top.
Flat white milk is microfoam — fully steamed with fine bubbles integrated throughout, creating a silky, glossy texture. A good flat white has a paint-like consistency to the milk, and baristas often use it to create latte art.
3. Size and Intensity
Cortados are smaller (60–120 ml total) and stronger. Flat whites are larger (150–180 ml total) and smoother. If you want an intense espresso experience with just a touch of milk, cortado. If you want a proper sit-down coffee that still lets espresso shine through, flat white.
Cortado vs Flat White vs Cappuccino: Three-Way Comparison
| Cortado | Flat White | Cappuccino | |
|---|---|---|---|
| Volume | 60–120 ml | 150–180 ml | 150–180 ml |
| Espresso | 30–60 ml | 30–60 ml | 30–60 ml |
| Milk ratio | 1:1 | ~1:3 | ~1:3 |
| Milk texture | Warm, minimal foam | Microfoam (velvety) | Microfoam + thick dry foam layer |
| Foam layer | Minimal | Thin flat microfoam | Thick dry foam (1–2 cm) |
| Strength | Strong | Medium | Medium |
| Best for | Espresso lovers who want a touch of milk | Milk and espresso balance | Creamy texture, foam experience |
Which Is Stronger — Cortado or Flat White?
The cortado is stronger. With a 1:1 ratio versus the flat white’s ~1:3, the cortado has significantly more espresso relative to milk. You taste the coffee more directly in a cortado.
That said, both use the same espresso dose (usually a double shot or double ristretto). The flat white isn’t weaker because it has less espresso — it’s diluted by more milk.
When to Choose Each
Choose a cortado if you:
- Love the flavor of espresso but find straight shots too intense
- Want a small, quick coffee with genuine espresso character
- Prefer minimal dairy
- Like drinks in the Spanish/European tradition
Choose a flat white if you:
- Want a balance of creamy milk and espresso
- Prefer a larger, slower-sipping coffee
- Enjoy velvety microfoam texture
- Like Antipodean-style coffee culture
How to Make Both at Home
Cortado
- Pull a 60 ml double shot into a small glass
- Steam 60 ml whole milk to 60–65°C (140–150°F) with minimal foam
- Pour the warm milk over the espresso
Flat White
- Pull a 60 ml double ristretto
- Steam 110–130 ml whole milk to 60–65°C with velvety microfoam
- Pour over the ristretto, pouring through the foam to integrate it

Frequently Asked Questions
Is cortado stronger than flat white? Yes. The cortado uses a 1:1 espresso-to-milk ratio, while the flat white uses roughly 1:3. With the same espresso dose, the cortado delivers a more concentrated, coffee-forward flavor.
Is a cortado just a small flat white? No — they differ in milk ratio and texture. A cortado isn’t just a mini flat white; it has proportionally much more espresso and less-textured milk. Reducing a flat white’s size doesn’t make a cortado.
Can I order a cortado at Starbucks? Starbucks has a cortado on some menus (particularly in select markets), made with two ristretto shots and steamed milk. It may be listed as “Starbucks Cortado” on their app.
What’s the difference between a cortado and a macchiato? See our Cortado vs Macchiato guide for the full comparison. The key: a macchiato is espresso “stained” with a very small amount of foam or milk, while a cortado uses equal-ratio warm milk.
Is flat white the same as latte? No — a flat white is smaller and more concentrated than a latte. See our Flat White vs Latte guide for details.
