What Makes Costa Coffee Flat White Special?
Costa's Flat White showcases expertly pulled espresso shots blended with velvety textured milk. The balance between intense coffee and creamy sweetness creates something truly special. Our baristas carefully steam the milk to achieve that signature smooth microfoam. This creates a rich mouthfeel that coffee lovers genuinely appreciate and savour.
Best Food Pairings with Costa Coffee Flat White
Pair your Flat White with our fresh croissants for a classic breakfast combination. Sweet pastries like chocolate twists complement the coffee's intensity beautifully. Savoury options such as toasted sandwiches work wonderfully too. The milk's sweetness balances perfectly with both sweet and savoury treats.
