What is the best coffee machine for one person?

Best overall for one person: Nespresso VertuoPlus if you want fast, low-effort coffee with minimal cleanup. It makes single servings reliably, takes little skill, and avoids brewing a whole pot.

If you care more about taste and lower long-term cost, choose the AeroPress Original. If you want true espresso-style drinks at home, choose the Breville Bambino Plus. If you want basic drip coffee and sometimes a travel mug, choose the Technivorm Moccamaster Cup-One.
