A device and method for preparing hot beverage while combining roasting the brewing in the same device. When non-roasted or semi roasted grinds or scrunched leaves are used, completion of the roasting is performed by the device to a desired level of roasting. Thereafter brewing is performed in a desired temperature and a controlled pressure. The grinds or scrunched leaves can be provided packed in a capsule.
