To make a 16 ounce (grande) Starbucks drink, you’ll need 2 Nespresso espresso or ristretto capsules. You can also use 1 Vertuo double espresso.
With the Vertuo machine capsules, only use espresso capsules and not the coffee capsules that make 7.77 ounces.
Starbucks uses 2% milk for their Iced Lattes but you can use any milk you like including almond milk or oat milk.
To sweeten without adding flavors, use a simple syrup, which will mix into the drink the easiest. Use flavored simple syrups like vanilla to sweeten and flavor the drink.
If you don't have an espresso machine or a Nespresso, you can use instant coffee. Combine 1 tablespoon of instant coffee and 1/4 cup hot water to replace the 2 shots of espresso in the recipe.
Out of all espresso-based drinks, lattes are made with the most milk. If you want more of a coffee taste, use less milk or add another shot of espresso.
