There are several alternative ingredients that can be used to enhance the flavor of a matcha latte beyond just traditional milk. For those looking for added sweetness, honey or agave syrup can be incorporated into the drink. Vanilla extract or flavored syrups such as caramel or lavender can also provide unique twists on the classic matcha latte flavor profile. Additionally, spices like cinnamon or nutmeg can add warmth and depth to the beverage. Experimenting with different types of milk such as oat milk or coconut milk can introduce new flavors and textures into your homemade matcha latte.
