The word "macchiato" has become a bit of a red flag for baristas because many people don't know the difference between a true macchiato and something more akin to a sweet latte.
While Starbucks’ macchiato comes in a 12 to 20-ounce cup with vanilla syrup, milk, and caramel, real macchiatos come in a small glass with two ounces of espresso and a little milk.
Due to Starbucks’ departure from the actual beverage, customers ordering a macchiato has become a bit of a headache for baristas serving up espresso drinks at other coffee shops.
