I have recently bought an espresso machine and I was struggling with what coffee (the one I bought from the store tasted like it was boiled for hours) to use with it. I emailed Coffee Fool and the questions they asked me (how do I like my coffee to taste, what's my coffee routine) helped me realize what I actually want and them recommend the right products. The Vienna I use now (the other two in the picture wait their turn) tastes smooth, balanced, not bitter nor burned like the one from the store. I now feel that I am using the machine to its full potential providing me with daily enjoyment.
