A macchiato consists of espresso with what?

Traditionally, the macchiato is made by combining a shot of espresso with a small splash of milk. However, many other variations are available, including the latte macchiato, which is made by adding a shot of espresso to a glass of hot milk. Because the macchiato is usually made using just a small amount of milk, it has a much stronger flavor than other coffee drinks. It’s also much smaller than other drinks, with a standard serving clocking in at just 1 1/4 ounces.
