I have a moka pot
I'm really happy with the coffee from this. However, after I've poured the first cup out, if I leave the heat on (however low), the coffee gets a metallic taste to it. If I turn the heat off then it goes cold.
So, my questions are: is this kind of coffee maker only good for the first cup? If not, how can I avoid either outcome? Also, can anyone tell me why it gets this metallic taste to it?
