For people who like a sturdy and tasteful foam layer, choose a De'Longhi fully automatic machine with LatteCrema technology. The De'Longhi LatteCrema technology automatically froths milk. The milk reservoir mixes steam, air, and milk in the best ratio to a creamy foam. This goes straight from the reservoir into your cup. After use, the milk system cleans itself automatically. Is there still enough milk in the reservoir? Store it in the fridge for next time.
