Types of Coffee Drinks: Every One, by Ratio and Family

By Coffee Studies Editorial·Published November 13, 2026·5 min read

Quick answer

Coffee drinks fall into five families: straight espresso (espresso, ristretto, lungo, Americano), espresso with milk (macchiato, cortado, flat white, cappuccino, latte, mocha), brewed coffee with milk (cafe au lait, egg coffee), cold (iced latte, espresso tonic, affogato) and coffee with a spirit (Irish, carajillo, Spanish). What separates drinks inside a family is the ratio and the cup: a cortado is espresso and milk in equal parts in a 4 oz glass, a flat white is a double shot under microfoam in 5 to 6 oz, a latte is one part espresso to three or four parts milk in 10 to 12 oz. The caffeine follows the shot count, about 63 mg a shot by USDA, not the size of the cup.

Every coffee drink you can order is a few ingredients in a ratio, served in a particular cup. Once you know the ratio, the names stop puzzling you: a cortado is espresso and milk in equal parts, a flat white is a double shot under thin foam, a latte is one part espresso to three or four parts milk. Here is every common drink you will meet, in five families, each with its ratio, its cup and its caffeine, and a link to the full page when you want more.

How much caffeine is in each drink?

Count the shots. A shot gives you about 63 mg by USDA, so a double-shot drink gives you about 126 mg whatever size the cup, and an 8 oz drip coffee at 95 mg gives you more than any single-shot drink. [1]

The chart is the reason a flat white feels stronger to you than a latte. It is not stronger per shot; it has two shots in less milk, so you taste the coffee more and you drink the same caffeine as a double latte.

Family 1: straight espresso

Coffee and water, nothing else. What changes is how much water you run through the same dose. [2] [3]

If you want more coffee flavour, go shorter; if you want more cup, go longer or add water. When you add water after the pull (Americano) you get a different taste from running more water through (lungo), because the lungo keeps extracting.

Family 2: espresso with milk

The same shot, with steamed milk in a rising ratio. Read this table top to bottom and you watch the milk go up and the coffee taste go down.

Mochaone or twoa latte with chocolate syrup or powder, often cream on top10 to 12 ozMocha
Breveone or twoa latte made with half-and-half instead of milk10 to 12 ozLatte

The three you are most likely to confuse are the middle three. You can tell them apart by the cup and the foam: cortado in a glass with almost none, flat white in a small cup under a thin shine, cappuccino in a small cup under a thick cap. The full comparison is on its own page: latte vs cappuccino vs flat white.

Family 3: brewed coffee with milk

Not espresso. These start from drip, French press or a phin filter, which is why you count the caffeine by the cup rather than the shot.

Family 4: cold

Espresso or brewed coffee over ice, with or without milk. The caffeine is whatever you put in; ice changes nothing for you but the volume.

Family 5: coffee with a spirit

Hot coffee, a measure of alcohol, usually sugar and cream. You are drinking a cocktail that happens to carry a coffee's worth of caffeine.

What to do

  • Want the coffee taste? Stay near the top of the milk table: espresso, macchiato, cortado, flat white.
  • Want a mild, milky cup? Latte or mocha, and ask for one shot.
  • Watching caffeine? Count shots, not ounces. One shot is about 63 mg; a drip coffee is about 95.
  • Ordering abroad? The ratio travels better than the name. Ask for "a double shot with a little milk" and you will get a cortado anywhere.

The short version

Five families, one rule: inside a family, the ratio and the cup define the drink you get, and the caffeine follows the shot count at about 63 mg a shot. Learn ten ratios and you can read any menu in the world.

Frequently asked questions

What are the 12 types of coffee drinks?
There is no official twelve, but the dozen you will meet on almost any menu are espresso, ristretto, lungo, Americano, macchiato, cortado, flat white, cappuccino, latte, mocha, iced latte and cold brew. Learn the first ten as ratios of espresso to milk and you can read any menu.
What are the top 10 coffee drinks?
By how often you will see them ordered: latte, cappuccino, Americano, flat white, espresso, mocha, iced latte, cortado, macchiato and cold brew. That is menu frequency, not a ranking by quality; the best drink is the one whose ratio matches how much milk you want.
Which coffee drink is the strongest?
Per sip, a ristretto or a straight espresso; per cup, whichever has the most shots. USDA puts restaurant espresso at about 63 mg of caffeine per 1 oz shot, so a double-shot flat white and a double-shot latte carry the same caffeine, about 126 mg, however different they taste. An 8 oz drip coffee is about 95 mg, more than a single-shot anything.
Which coffee drink has the least caffeine?
Among espresso drinks, anything built on one shot, about 63 mg: a single espresso, a macchiato, a traditional cappuccino, a single-shot latte. A cafe au lait made with half drip coffee is lower still, around 48 mg for 8 oz. Decaf versions of any of them drop to a few milligrams.
What is the difference between a latte, a cappuccino and a flat white?
Milk and foam. A cappuccino is a single shot with equal thirds of espresso, steamed milk and thick foam in 5 to 6 oz. A flat white is a double shot under thin, glossy microfoam in 5 to 6 oz, so it tastes stronger. A latte is one or two shots in 10 to 12 oz of steamed milk with a thin foam layer, the mildest of the three.
What is the difference between an Americano and drip coffee?
How the water meets the coffee. An Americano is espresso diluted with hot water to a drip-like volume; drip coffee is water passed through grounds under gravity. They land at similar strength in the cup but taste different, and a single-shot Americano has less caffeine than an 8 oz drip, about 63 mg against 95.
