To make a vanilla latte, combine espresso, steamed milk and vanilla flavoring. An espresso machine gives the best results both for coffee brewing and for steaming the milk, but other methods and equipment can be used.
Whatever equipment and methods you have available, a tasty vanilla latte is within your reach. Start by brewing your espresso or strong coffee using an espresso machine, vacuum pot, French press or your preferred method of brewing. You need about 1.5 to 2 ounces of brewed espresso for your latte.
While your coffee or espresso brews, make some warm, frothy milk. Do this by using the steamer wand on the espresso machine, by rapidly whisking air into the milk while heating on the stove or by vigorously shaking the milk in a container until frothy and then heating it in the microwave for a few seconds. It takes about 1 to 1 1/4 cups of milk. Add approximately 2 tablespoons of vanilla syrup to the milk, either before or after the heating and frothing step.
When both the espresso and vanilla flavored milk are ready, begin by adding the espresso to your cup. Then gently pour in the warm milk, withholding the froth with a spoon. Finally, spoon the milk froth onto the top of your latte. A proper latte should have a ratio of about 1/3 espresso and 2/3 milk, with a layer of froth on top. By comparison, a cappuccino should be 1/3 espresso, 1/3 steamed milk and 1/3 milk froth.
