title_body: Bean to Cup cappuccino coffee is never hot enough
upvoted_answer: Many of these fully automatic machines heat the milk by combining steam and milk. In my experience, those machines do not take into account the temperature of the milk, they simply mix steam and milk at a fixed ratio. Assuming the steam has a fairly constant temperature, the temperature of the heated milk will mostly depend on the temperature of the cold milk. Simply stated, cooler milk will produce cooler heated milk.
  If you use milk straight from the fridge, it might be wise to heat it a bit yourself before passing it through the machine. Microwaving the milk you need to slightly below room temperature and then feeding it through the machine's frothing process should increase the temperature of the heated milk. By extension, the temperature of the final drink will be higher as well.
  Be careful not to pre-heat the milk too much, then the machine could heat it so that you get unwanted chemical reactions (e.g. lactose reacting with proteins) or that the final product comes out steaming.
