Why isn't my coffee warm?
Firstly, the brew temperature of your machine has a negligible effect upon the temperature of your drink. Brew temperature will only effect flavour of your espresso. eg, colder for more acidity and warmer for more bitter sweetness.
Secondly, when steaming milk you should steam until the jug is hot to touch. Never overheat the milk as overheating will reduce the milk’s sweetness and it can even burn the milk.
The secret to a warm drink is to pre-warm the cups with boiling water. With pre-warmed cups you will get a warm drink to enjoy :)
