Making the Most of Your Signature Latte
When ordering, consider your taste preferences and nutritional goals. For a richer and creamier latte, oat milk adds calories and fat but reduces sugar, ideal for those seeking fullness and texture. Coconut milk offers a lighter option with fewer calories and fat. If you prefer to keep calories closer to the default, stick with standard milk. Adding syrups or extras enhances flavour but increases price without impacting calories as indicated.
Choosing the Small size keeps your calorie intake low at 117 kcal, while the Large serves up a more substantial 179 kcal. Pick accordingly based on hunger and calorie needs. For a bolder coffee hit, add an extra espresso shot, keeping in mind it increases cost but does not change nutrition values provided.
