I would like to second this solid advice.

I have a very nice grinder: a solis caffissima digital coffee grinder. It is available under a different brand name in the US I think.

I make filter coffee with a very basic earthenware filter holder with melitta high quality yet very normal filters and sometimes I mix it up with an aeropress which offers a different type of taste because of the low acidity way of making coffee. I just drip the coffee into a nice thermos so I can make 4 cups in one go and just pour from the thermos.

My coffee is much nicer than I get in most places, both professional and at homes and it doesn’t cost me a lot in effort, money and, very importantly, workspace footprint.

Espresso machines require a lot of space and maintenance and trouble to make.

Having said all this, I am quite intrigued about all the stories about the negative effects of coffee. I just thought it was about influencing sleep, but I had never thought about the memory and mood effects. I will study this some more in the coming months.
