A short Macchiatto? Similar to a latte? I think youre confusing it with a top up long macchiatto.
A short macchiatto is just a shot of espresso with a cap of milk/foam. A traditional long macchiatto is a double shot with a cap of milk/foam. A top up long macchiatto is a double shot with milk topped up to the rim of the glass (150 - 200mL?) Not exactly sure on the amount.
And since you like milk why not try a flat white?
