If you have, you're more than likely from Melbourne, or visited Melbourne, or a just an absolute coffee lover, because this coffee born in Australia and affectionately named the 'Magic' won't appear on any menu board, and is more of a secret menu item!
Magic is a double shot ristretto, so just the first half and sweetest part of the espresso combined with flat white milk, served in a 5 ounce cup filled to 3/4 full. When you compare that to a Flat White which is made from a double shot of and a bit more milk, and a cappuccino which is made from a single shot, also with a bit more milk, the Magic kind of sits in the middle of these two, with the strength of a flat white, but with extra sweetness. Its usually served in a smaller cup and the milk temperature is a little cooler than standard to assist with enjoying coffee on the go.
Try it, let me know what you think of the Magic! If your barista gives you a blank stare, be confident and declare, a double shot ristretto with 130ml of milk (combined with the 30ml of espresso, you'll end up with a 160ml drink, so the cup wont be full to the brim in a standard 180ml cup, intentionally).
