A flat white is a 5–6 oz espresso drink with silky microfoam integrated throughout. A macchiato is a 1–2 oz espresso shot with just a small amount of milk foam on top — no steamed milk, no volume. The macchiato is one of the most concentrated, coffee-forward drinks you can order. The flat white is creamy and smooth while still being espresso-dominant.

What Is a Flat White?
A flat white originated in Australia and New Zealand in the 1980s. It’s a double shot of espresso with approximately 4 oz of whole milk textured into silky microfoam — no thick foam layer on top, just a thin, glossy surface.
What makes it different from a latte:
- Smaller (5–6 oz vs. 8–12 oz)
- Higher espresso-to-milk ratio
- Microfoam is fully integrated, not sitting on top
- Stronger-tasting than a latte despite similar ingredients
What makes it different from a cappuccino:
- No thick dry foam layer
- Microfoam is silky and thin, not airy and dry
- Similar size, but the flat white has a “flat” (smooth) top, not a raised foam dome
The flat white’s key characteristic is the microfoam — milk steamed to 140–150°F until it has a uniform, silky texture. This requires proper milk steaming technique. Without silky microfoam, you don’t have a flat white.

What Is a Macchiato?
“Macchiato” means “stained” or “marked” in Italian — the name describes what the drink is: espresso stained with a small mark of milk.
Traditional Italian macchiato construction:
- Pull 1–2 shots of espresso (1–2 oz)
- Add a tablespoon of milk foam or a small splash of steamed milk
- Serve immediately in a small demitasse cup
The milk’s purpose is to slightly soften the espresso’s acidity and bitterness — not to add creaminess, volume, or sweetness. A macchiato is still fundamentally an espresso drink. If you want coffee flavor with just the edge taken off, this is your drink.
Critical distinction — the Starbucks macchiato:
The Starbucks Caramel Macchiato and Latte Macchiato are completely different from a traditional espresso macchiato. Starbucks macchiatos are large (12–20 oz) milk-forward drinks with vanilla syrup, a full 8+ oz of steamed milk, and espresso poured on top. The name “macchiato” is used loosely. If you’re ordering at a specialty coffee shop expecting Starbucks, clarify which you want.

Milk: The Core Difference
The milk difference between a flat white and a macchiato is not a matter of degree — it’s a structural difference:
Flat white milk: ~4 oz of whole milk steamed to silky microfoam. The milk is fully integrated into the espresso, creating a unified creamy drink. The milk’s fat and protein round out the espresso flavor and add body.
Macchiato milk: ~1–2 tablespoons of milk foam. The foam floats on the espresso surface. It’s a “mark,” not an ingredient. The espresso remains dominant. The milk doesn’t add creaminess — just a slight textural contrast and a small reduction in bitterness.
This means:
- A flat white is a milk drink built on espresso
- A macchiato is an espresso drink with a milk accent
Strength Comparison
| Per oz (concentration) | Per serving (total caffeine) | |
|---|---|---|
| Flat white | ~21 mg/oz | ~128 mg (2 shots) |
| Macchiato (traditional) | ~42–64 mg/oz | ~64–128 mg (1–2 shots) |
| Espresso | ~64 mg/oz | ~64 mg (1 shot) |
Is a macchiato stronger than a flat white?
Yes, per ounce. A macchiato has almost no dilution — it’s near-pure espresso with trace milk. A flat white dilutes two shots across 5–6 oz of milk. But per serving, the total caffeine is similar (both use 1–2 shots). The macchiato just tastes significantly stronger because you’re drinking less milk.
The Starbucks Versions (vs. Traditional)
Starbucks sells “macchiato” drinks that differ substantially from the Italian original:
| Traditional Macchiato | Starbucks Macchiato (Tall) | |
|---|---|---|
| Size | 2–3 oz | 12 oz |
| Milk | Tablespoon of foam | 8–9 oz steamed milk |
| Syrup | None | Vanilla syrup |
| Espresso | 1–2 shots | 1 shot |
| Drizzle | None | Caramel drizzle |
The Starbucks flat white is closer to the original — a double shot with steamed whole milk in a 12 oz cup — though still larger than the Australian original (typically 5–6 oz).
When to Choose Each
Choose a flat white when:
- You want a creamy, espresso-forward drink that’s smaller and stronger than a latte
- You appreciate good microfoam texture and latte art
- You want something between a cortado and a latte in size and intensity
- You prefer coffee shop quality over a large volume drink
Choose a macchiato when:
- You want the flavor and intensity of espresso with just the bitterness slightly softened
- You’re not interested in a milky or creamy drink
- You want something quick and small
- You’ve had espresso straight and want just a touch of milk
Three-Way Comparison: Macchiato vs Flat White vs Cappuccino

| Milk | Dash of foam | 4 oz microfoam | 2 oz steamed + 2 oz foam |
| Foam | Minimal | Thin, silky | Thick, dry |
| Espresso shots | 1–2 | 2 | 2 |
| Strength feel | Intense | Rich | Balanced |
| Best for | Pure espresso fans | Milk + espresso balance | Classic café experience |

Frequently Asked Questions
Is macchiato stronger than flat white?
Per ounce, yes — significantly. A traditional macchiato is almost undiluted espresso (~64 mg caffeine in 2 oz). A flat white has the same caffeine spread over 6 oz of milk. Per serving, the caffeine is similar (both use 1–2 shots), but the macchiato feels much stronger because you’re drinking concentrated coffee with minimal milk.
What is the difference between a flat white and a macchiato at Starbucks?
At Starbucks, the difference is significant. The Starbucks flat white uses whole milk steamed to microfoam (similar to the original). The Starbucks macchiato (Caramel or regular) is made with vanilla syrup, steamed milk, espresso poured on top, and caramel drizzle — it’s more like a layered latte than a traditional macchiato. Both are 12 oz+ drinks. Neither matches the small-volume intensity of their traditional Italian counterparts.
What type of person orders a flat white?
Usually someone who finds lattes too milky but appreciates good espresso flavor with cream texture — common among specialty coffee drinkers who’ve worked their way through the menu. It’s also popular in Australia and New Zealand where it originated, and among people who want something smaller and stronger than the standard café latte.
What is the closest thing to a flat white?
A cortado — equal parts espresso and flat milk (no foam), served in 3–4 oz. The cortado is slightly smaller and less creamy than a flat white, with a 1:1 espresso-to-milk ratio vs. the flat white’s roughly 1:2. A wet cappuccino (extra milk, minimal foam) is another close alternative. → Cortado vs Flat White
