Why do I think instant coffee tastes good

Instant coffee is mostly flavored and not so bitter. What is ground now is basically the taste of coffee itself. Just like photography, sometimes the effect of SLR is not as good as that of mobile phone or digital camera, because SLR only records the light and shadow at that time, and both mobile phone and digital camera adjust the photos, so sometimes the effect of mobile phone digital card machine is better than that of SLR.
