that said, myself and one other person are familiar with making espresso, the others are not. the plan is for me to dial in the grind for the espresso so that whoever is making it can just hit a button and get the correct amount of coffee, put in the portafilter and tamp it.
I have a Niche Zero and a Breville Smart Grinder Pro.
If I had to buy a grinder for the office I would buy the Breville.
Super easy to use, reliable time dosing and very clean.
I don't think that in my office single dosing would be a good solution, on the contrary.
If using two different blend is a must I would buy two of them
. The red model would be perfect for decaf
But that is my office.
