So you say:
IzzyAg whatever it takes to make good quality coffee. The title barista does not interest me, as coffee is not the main focus in my concept.
IzzyAg My target market is not coffee lovers. That said, I would still want something of a higher standard that people still taste the difference compared to a coffee at the station.
That feel contradictory to me. The coffee at the station is most likely provided by a bean to cup machine, (e.g.: you press a button, it grinds the coffee, and it makes the beverage you want) and that machine is periodically cleaned and maintained by a company which supplies those. There are quite a few of those out there.
You have no interest in learning to make coffee - therefore leave it to someone who has, or to a machine that’s programmed to do so. If you put a machine there and expect it to just make coffee without any care from you, the product will be to match.
If I were you, I’d simply get a bean to cup machine - a Delonghi Magnifica for example. How long will it last in your environment? Who knows.
