During working week I use a 10cup Stainless Steel stove top Bialetti und illy-Espresso.
Delivers one mug for breakfast, one for takeaway that keeps me awake until second breakfast break and gives me time to prepare my breakfast while "boiling up".

For more volume or on weekend I use a Melitta/Friesland porcelain cone with Melitta Gourmet bags and small batch Arabica from a local roaster or French small batch Arabica when I made my way to France few times a year.
