A cortado is not dissimilar to a macchiato. Both contain the same amount of espresso, except the macchiato has a little less milk and is a bit smaller, which results in a slightly more bitter taste.
A cortado is generally smaller than a flat white and possesses a much stronger taste due to the lightly steamed milk. Additionally, the flat white can be likened to a small latte as it has textured milk, making it hotter with a much thicker taste.
