Tastes like coffee.

It's not bad if you actually pay attention and don't just leave it percolating forever like a madman.

It just has a bad rep because ~~people~~ psychos will let it keep percolating for way too long and it over extracts the beans and gets really bitter and gross. If you use it like you should it tastes fine, maybe not as good as other forms of coffee making but it isn't bad per se.
