The simplest version: coffee is the whole drink; a latte is an espresso + milk combination.
Latte vs Coffee: Side-by-Side Latte Drip Coffee Base Espresso (7–9 bars pressure) Brewed coffee (gravity/filter) Milk 4–6 oz steamed milk None (traditionally) Volume 8–12 oz typical 8–16 oz typical Caffeine (12 oz) ~75–150 mg (1–2 shots) ~120–165 mg Calories ~120 kcal (whole milk) ~5 kcal (black) Flavor Creamy, mild, slightly sweet More bitter, lighter-bodied Strength Weaker caffeine per oz Stronger caffeine per oz Espresso machine?
