EDIT:
I’m new to this coffee drinking malarkey and haven’t really a clue about any of it.
I didnt got to Coffee school.
I’m in my early 40s and have only started to drink it, recently.
I usually get a coffee from a local Costa, once or twice a day.
A medium black.
This, I’m thinking, is Fresh coffee as opposed to instant, I’m guessing.
