The sound is amazing ! I'm fascinated because most stoves here are electrical so we don't have the hissing gas sound which i've always liked for some odd reason...
I use this same pot and I love it. It looks like you might be over-extracting though, unless you left it brewing just for the sake of the video. It's usually a good idea to take the pot off the burner right after that heavy flow starts.
i think its a Cuban coffee, espresso.
nice job.
