Cortado vs Flat White: Milk, Size, and What to Ask

A cortado is usually the smaller order, with less milk around the espresso. A flat white gives you a larger milk drink with a thin layer of fine foam.

Compare the drinks before you order

Use La Marzocco Home's drink guide as one pair of examples. Both drinks start with a double shot. The table shows what the maker specifies and what to ask at your café.

Check	La Marzocco cortado example	La Marzocco flat-white example	What to ask at a café
Coffee base	Double shot, about 2 U.S. fl oz liquid	Double shot	How many shots are in this size?
Milk named in recipe	About 2 fl oz to steam and combine	About 4 fl oz to steam and combine	How much milk reaches the finished cup?
Serving	4.5 fl oz glass	Cup size not specified in this example	What size cup will I receive?
Finished top	Smooth steamed milk	Fine foam about 0.5 cm or thinner	Is the top thin and smooth or thick and airy?

La Marzocco's 2 and 4 fl oz milk amounts are instructions to steam and combine. The guide does not measure how much reaches either cup. You cannot calculate the exact difference between the finished drinks from those numbers.

Why the milk changes the first sip

With the same coffee base, a shorter milk pour can leave espresso flavor more prominent. With more milk, the first sip can taste softer. Nescafé's comparison also presents the cortado as smaller and the flat white as larger with more textured milk.

A large, dry foam cap makes a different first sip from milk whose small bubbles blend into the liquid. If you dislike a thick cap, ask for a thin, smooth milk top. Latte art can appear on either cup without telling you the recipe underneath.

Temperature can change how you experience the drink, too. La Marzocco's cortado method steams milk to 130 to 140°F, while its flat-white method names 140 to 150°F. Those ranges belong to its examples. If you make either drink at home, use the safe instructions for your exact machine and milk vessel.

Choose by the café's recipe

Suppose a café tells you that both drinks use the same double espresso. Its cortado is a small glass with a short milk pour; its flat white fills a larger cup with thinly textured milk. This is a hypothetical café, used to show the decision.

Choose the cortado if you want the espresso to stay closer to the front of the sip. Choose the flat white if you want more warm milk around the same coffee base.

Now change one detail. Suppose the café makes its cortado with one shot and its flat white with two. You cannot use the first comparison to predict which drink has more caffeine or how strong each will taste.

Ask for the shot count and, if you care about caffeine, the café's own information. Milk changes flavor concentration in the cup; it does not remove caffeine from the espresso already added. Bean choice, shot recipe, and serving size can also differ.

You can order without reciting a ratio. Try: “I want a small espresso and milk drink with a short milk pour. How do you make your cortado?”

For a longer drink, ask: “Does your flat white use the same shots, and is the milk smooth with a thin top?” The answers let you compare that café's two cups. If the staff cannot give exact volumes, an approximate cup size and shot count still help.

If you need a dairy-free drink, ask which milk the café uses and check its allergen information. A different milk can change the taste and foam. Do not assume the photograph, menu name, or drink size tells you the ingredients. The two cups in the photograph have an unknown recipe and unknown volumes.

Compare them at home with one coffee base

If you already have the equipment and want to feel the difference, make two small cups from one repeatable coffee recipe. La Marzocco's guide gives a general double-shot starting point of 18 g dry coffee and about 28–36 g espresso. Your basket or capsule instructions may use another amount. Keep the coffee recipe the same for the comparison, and note the espresso mass or program used for each cup.

For the cortado direction, follow our measured cortado recipe or La Marzocco's cortado example. For the flat-white direction, follow our flat-white recipe and pour more smooth milk with only a thin foam top.

The published cortado recipe also shows a Nespresso method: 40 mL capsule coffee plus 20 mL warm milk and 2 spoonfuls of foam. Nespresso lists 100 mL cold milk for the frother; 20 mL warm milk goes into the cup.

Set a suitable cup with espresso on a scale that can hold a hot cup. Set the scale to zero, then pour milk and foam. Write down the grams added to the cup. Repeat for the second drink while keeping the coffee base steady.

Your note can say “same double shot; first cup 40 g poured milk; second cup 90 g poured milk.” Those masses are hypothetical examples, not source measurements or site test results. If no liquid spills, 32 g espresso plus 40 g poured milk gives a 72 g drink. The scale helps you repeat the cup you prefer.

Taste when both drinks are safe to sip. If the lower-milk cup feels too sharp, keep the espresso recipe fixed and add a little more milk next time. If the higher-milk cup hides the coffee flavor you want, use less milk on the next pour.

If the espresso tastes sharp or bitter before milk goes in, adjust the coffee base first. How to dial in espresso explains how to keep dose and drink weight steady while changing the grind. A milk comparison will be easier to judge once both cups start with coffee you like. The espresso ratio calculator can show a target drink mass from a dry dose; it does not calculate how much milk a café adds.

Steam, hot milk, and metal parts can burn you. Follow the exact manual for your machine or frother. Use its fill marks, stop and power-off controls, cleaning steps, and cooling time.

Do not apply a steam-wand position from an article to another model. If the equipment cannot safely texture milk, use a suitable frother under its own instructions or ask the café to make the comparison.

How published recipes vary

Breville's flat-white page lists one espresso shot, while La Marzocco's version starts with a double. Ask about the serving at the café where you will order.

We read the linked La Marzocco, Nespresso, Breville, and Nescafé pages on September 26, 2026. We did not prepare, taste, own, test, or measure these drinks. The table records source examples, and the home comparison is a procedure for you to try with your equipment. Milk is an allergen; check the product label and café information when that matters to you.

Ask how many shots each cup uses and which drink has the shorter milk pour. Those two answers will usually get you closer to the drink you want than the name alone.
